The contents of these applications are hereby incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-phase brushless motor 'more particularly, a multi-phase arrangement of its paste armature members, which are associated with each other with the pole pole faces of the field magnet members and the corresponding pole faces of the corresponding armature members. Skewed for use in brushless motors. [Prior Art] In the case of a general-purpose rotating electrical machine, regardless of the operation of a DC motor or an AC motor, the magnetic principle of the rotor and the stator (4) is mutually exclusive and repulsive. For the production of - linear force, the mosquito and rotor surfaces are replaced by stators and movers of linear motors, but the principle of operation is the same.

Kawai g, in U.S. Patent No. 5,435,518, teaches that each magnetic circuit of a plurality of electromagnets of a power generation, placement & Since the electromagnets are arranged, the respective magnetic circuits are independent of each other so that the decomposition is magnetized to be independent. The electromagnets are irrelevant and the electromagnets are sequentially excited to control the rotor motion in a predetermined direction. By treating the magnets independently of each other, the processing of the 1333311 interference effect is processed, so that the energy applied to the electromagnet can be utilized most effectively to minimize the interference force that hinders the rotor motion. In the case of Maslov #人 in US Patent Licensing No. 679ΐ222, _〇ν et al. in US Patent Licensing Bulletin No. 6891306, Lu Weiting in the Republic of China Patent Grant No. 1272284 and the above-mentioned photo shoot, Lu Weiting, L et al. The brush motor 'is arranged by the independent electromagnetic ball arrangement on the armature to handle the magnetic flux switching interference effect between the moth lines, and is provided by the field magnetic pole magnetic iron and the armature electromagnet pole pair turned in the axial direction A very concentrated flux distribution allows the flux to be concentrated on a relatively large surface to promote high torque. And the sensor detects the relative position of the magnetic poles and the magnetic field at different times, and conveniently controls the armature electromagnetic body poles at different times. The coil current on the upper side causes the smooth running of the motor. In order to obtain a larger total effective air gap surface area, the surface of the pole pair of the electromagnet of the motor and the field pole magnet should be increased to provide a larger magnetic flux distribution, and by the concentration of the magnetic flux The distribution of the magnetic flux is improved. The construction of the motor architecture allows the motor structure to provide greater between the field pole magnet and the armature electromagnet by increasing the surface area of the field pole magnets and the opposing electromagnets that pass through the plurality of air gaps. The continuous magnetic flux creates a path to promote the concentration of Wei on the surface of the large surface, and further enhances the high torque capability of the motor.

Kawai, Masl〇v, Lu Weiting et al. in the patent confirmed the concentration of magnetic flux and the maximum utilization of magnetic flux, and the minimization of magnetic flux loss and interference effect, and the larger total effective air gap surface area 'and the motor in A better geometric balance is obtained in the space, 6 z has the power to reduce the force _ 附崎·, has been described 5 = coffee towel. _, in the balance, the coil of the electric piece is connected to the core of the magnetically conductive part, but the electromagnet can be isolated to isolate the torque, but when the permanent magnet passes through the electromagnet, a plurality of magnetic electromagnet elements are formed. Taking the external torque and causing the pulsation of the output torque will have an adverse effect on the operation of the motor. In a brushless motor, the torque is the main cause of the motor's control performance degradation = the saddle force (four) erection group, and the rate of change of the magnetoresistance between the control rotor and the scorpion. Torque == Technique: Use:: Less torque due to the presence of an electromagnet. But reducing the flux of the motor will cause a drop in output. The interelectrode gap along the multi-moving one-sequence electromagnet wheel thinks that each _, ===: for each parent phase phase group makes the armature current control of the motor more complicated. In a two-phase electro-optical with two sets of phase coils, the two phase currents are all one, , seven sine waves and are mutually offset by a 90 degree phase. In a three-phase motor having three sets of phase coils, the three phase currents are all an alternating current sine wave and are phase shifted from each other by -12G degrees. For simplicity, the present invention is directed to the three-phase operation of the most common three-phase motors, and all of the statements of the present invention are also effective for motors that are more or less than three phases. A-A is a conventional plan view of the electromagnetic force in a conventional three-axis linear motor. In the figure, the Ding Chuan, and the 4-phase motor are arranged at various positions in the moving direction, and the plane development map of each phase electromagnetic force Fa, Fb, and Fc, which is scheduled to act in the moving direction, is due to the three of the three-phase armature of the armature. (4) _, the resultant force f of each phase electromagnetic force Fa, (3), & is a Tao value, and is shown in the figure. As mentioned above, the correct operation of the three-phase motor is suitable. 'For three phases, the beans consist of at least one induction coil per phase and must be formed along the direction of motion until a row of coils is formed; when all phases are When assigned, it means that a considerable amount of space is occupied in the direction of motion of the motor itself. Although traditionally, three-phase motors have taken into account the balance (4) considerations, but for the need for high torques, and the direction of movement is ,, can be overcome by adding more parallel air gaps to further increase the effective air gap surface area; Provides higher torque with limited space. Figure-B shows the arrangement of the basic components of a three-phase linear motor in accordance with conventional techniques. In the US Patent Licensing Bulletin No. 667_, b is resistant. _ et al. propose a kind of eve phase line!·sheng motor' shows how to arrange in three-phase linear motor in the first B picture; = machine _ 5a, 5b, 5e, and 120 degree phase deviation in each phase _ circle Jiang Wu is very close to the effect of green.

Among them, the strip 8 of ferromagnetic material can serve as a magnetic flux return path of her adjacent magnet arranged along the shift β, but this structure causes the arrangement of the magnetic flux to be affected by the adjacent magnetic pole. "In addition, the variation rate of the rotor-rotating mosquito pre-existing has a face-to-face variation; wherein, by changing the shape of the pole surface of the dipole pole or the rotor pole, and arranging the stator pole surface geometry and the rotor magnetic age geometry to be mutually skewed Μ 衡 衡 不 不 不 不 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 1 will not be detrimental to the original flux concentration performance of the brushless motor. In view of the above-mentioned tracing problems, the present invention has been improved, improved, and applied to the motor of the present invention. Therefore, in the various brushless motors of the above related applications, there is a need to reduce the pulsation of the output torque by the reduction torque.

The arrangement of a plurality of pole pairs on the shaft as a motor organization has been described in the above patent application. • S-step improvement. The fourth B picture is a change structure similar to the fourth a picture. The detailed sectional view of P is combined with the three parts of the brushless motor of the Republic of China. By increasing the surface area of the two magnetic poles of the |^: _ element and the opposing electromagnet element, the magnetic flux is concentrated on a relatively large surface, and the magnetic flux distribution can be improved to be more balanced. On the field magnet member as the rotor, the pole faces of the two magnetic poles 51cl, 52cl, 51c2, 52c2, 51c3, 52c3 of each magnetic element are not only arranged opposite each other in the first direction to be substantially opposite, and each of the magnetic elements Each magnetic pole of the magnetic pole 15 丄 33 3311 pole face has a corresponding pole face 65c2, 65c3 in the second direction.

Separated

Corresponding to the two magnetic poles of the respective magnetic components corresponding to the gas. Therefore, each of the permanent faces of the magnetic 7C member has three pole faces of magnetic field polarity, so that each of the magnetic pole faces of the magnetic 7G member is separated by an air gap slave. A part of the detailed cross-sectional view of the modified structure of the fourth embodiment of Fig. 4, which is a combination of three parts of the preferred embodiment of the brushless motor of the Republic of China Application No. 47394, which is arranged in the axial direction. The magnetic flux is concentrated on a relatively large surface by increasing the surface area of the magnetic poles of the magnetic element passing through the air gap and the opposing electromagnet elements. On the scene of the rotor as a rotor, the pole faces of the two magnetic poles 51d, 52d of each magnetic element are not only arranged in the first direction but opposite each other on the solid shell, and each magnetic pole of the two magnetic poles of the parent magnetic element The pole faces have corresponding pole faces in the second direction. The opposite poles of the pair of poles 61d, 62d of the magnet elements are divided by the respective air gaps and the two magnetic waves of the corresponding magnetic elements in the axial direction. Therefore, each of the permanent magnet poles of the miscellaneous element has three magnetic field poles of the same type, so that the pole faces of each of the magnetic poles interact with the corresponding poles of the paired poles of the stator via the air gap. In the fourth and fourth graphs, the electromagnet elements have approximately the same 1333311 pole face area, and the two elements of the magnetic element also have a pole face area of about _. In spite of the lack of magnetic conductive (4), the material has a polar surface area of an electromagnet element having a polar surface area of about _ size, and a magnetic element having a pole surface area of about the same size as the two magnetic poles of the rotor. The pole surface area is not the same—but the pole surface area of the pair of poles of an electromagnet 7L of the stator is about the same as the area of the two pole faces of the magnetic element of the rotor, which can promote the poles of the stator electromagnet tree. Rotor magnet

The magnetic flux distribution on the two poles of the sexual element is more balanced, and due to the balancing effect, a further geometrical balance of the motor can be achieved. This arrangement is beneficial to the almost no additional space and weight due to the better geometric balance of the motor in the m-cap and the increase in the wire area through the gas-magnetic element and the power-reducing element. Used in the environment and with further improvements in the flexible and safe operating characteristics of the motor. The fifth figure is the field pole of the brushless motor according to the fourth request. The magnetic poles of the two magnetic poles of the magnetic poles and the corresponding armature member electromagnet elements are opposite poles. Figure. Among the magnetic pole faces of the financial components, the corresponding pole parts of the electromagnet elements are illustrated as an example; the upper half shows the pole faces of the pair of poles of the three electromagnet trees of the complement. A planar layout along the moving direction; the lower half shows five sets of three adjacent magnetic elements = a planar layout of the permanent magnet pole faces 51 in the direction of movement, and the adjacent magnetic elements in the moving direction are separated by a gap 32. In the fifth figure, the permanent magnet pole faces of the magnetic elements above the pair of pole poles of the upper electromagnet element are corresponding, and the 1333311 of the middle_electromagnet element

In this structure, in order to drive the = member crane as a mover, in the moving direction, it is necessary to arrange a plurality of sets of electromagnetic ones of the phase, and sequentially excite the electromagnets in the moving direction to control the rotor motion. A predetermined direction; but when the money is running, the permanent magnets cause an additional torque due to the rhyme. She is in a money motor, the torque of the three brushless motor structures is accumulated; the motor has to leave a lot of space in the moving direction to arrange the necessary electromagnets, causing the motor to move in the direction = many spaces The side is unfavorable for the individual in which the motor is moving in the moving direction and the female volleyballs are connected in series and each independently moves. The first/A diagram is a field magnet member magnetic component of the multiphase brushless motor according to the first embodiment of the present invention, wherein the magnetic poles of the two magnetic poles are opposite to the corresponding pole faces of the corresponding armature member electromagnet components. Schematic diagram of the surface layout of the surface. In order to make the members of the armature of the fifth fiscal genus only the group of three adjacent electromagnet elements can move smoothly, the magnetic _ surface 61 of the hybrid component and the corresponding electromagnet τ are shown in the sixth figure. The corresponding pole face 51 is how to change the structure of the magnetic element and the corresponding electromagnet element in the fifth figure to achieve the effect described in the Figure-A. In the figure, the multi-phase brushless motor contains a magnet member and a member. The field magnetizer contains a pair of miscellaneous components with permanent magnets with two magnetic poles, and each of the miscellaneous components has only 1333311 per pole pole surface, showing a single-magnetic field polarity and a magnetic field with another magnetic pole face. The opposite polarity; the armature member contains multiphase electromagnet elements that are magnetically isolated from each other, and each pole of the coil-containing electromagnet element having a pair of poles has its own pole face; wherein the multiphase electromagnet element Arranged side by side with the magnetic element, and the two pole faces of each magnetic element are arranged in the first direction opposite to each other in the first direction, and each pole of the pair of poles of the Wei body element is divided along the moving direction The respective air gaps correspond to the two magnetic poles of the magnetic elements. The magnetic track moved by the electromagnet elements of each phase has no mechanical relationship with the electromagnet elements of the other phases, so that the electromagnet elements of one phase of the county do not interact with all the magnetic elements; and each magnetic element The two permanent magnets are separated from each other by a gap perpendicular to the (four) direction, and each magnetic pole of the plurality of magnetic elements is arranged in a moving direction along the moving direction magnetic pole, and the magnetic pole polarity is alternately arranged. The field magnet members of the stator are offset from each other by the impurity planes of the adjacent three magnetic elements in a direction perpendicular to the sense direction, and a three-phase current is added to the coils of a group of three adjacent electromagnet elements. The current waveform of each phase is - sinusoidal _, so that the motor obtains a substantially synthetic force, and only a set of adjacent three (four) magnet elements can control the member and the field magnet member to move in the moving direction. Square (10) - relative displacement. Although this offset can reduce the interference of the torsion torque to some extent; however, the extra torque generated by the permanent magnet through the electromagnet will still interfere with the motor operation. 6B is a surface of a corresponding pole surface of a pair of poles of a magnetic component of a field magnet member of a multiphase brushless motor according to a second embodiment of the present invention, wherein the magnetic pole faces are opposite to the corresponding electromagnet elements 1333311. A schematic diagram of a partial layout. Fig. 6B is a schematic view showing the planar layout of the surface portion of the corresponding pole face 51 of one of the two magnetic poles of the magnetic structure of the second embodiment having the magnetic pole faces 61 and the corresponding electromagnet components. In the figure, the multiphase brushless motor contains a field magnet member and an armature member. The field magnet member includes a plurality of magnetic elements including permanent magnets having two magnetic poles arranged in the moving direction, and each of the magnetic pole faces of each magnetic element exhibits only a single magnetic field polarity and is opposite to the other magnetic pole surface. The magnetic field has the opposite polarity; Lai Chengyu contains a plurality of coil-containing electromagnet elements having a pair of poles magnetically isolated from each other in the moving direction, and each pole of each pair of electromagnet elements has its own pole face . Wherein, each magnetic pole of the plurality of magnetic elements is alternately arranged with magnetic pole polarity N/s in the magnetic poles adjacent to the magnetic elements arranged in the moving direction, and the two magnetic pole faces of each magnetic element are arranged in the first direction In contrast to the shell, each pole of the pair of poles of the electromagnet element corresponds to one of the two magnetic poles of the magnetic element via a respective air gap in the direction of movement. Although the gaps 32 between the magnetic elements adjacent in the moving direction need not be identical, the gaps 33 between the electromagnet elements adjacent to each other in the moving direction need not be identical, so as to properly cooperate with each other, and the arrangement is preferably reduced. The torque ripple of the brushless motor. However, the pole faces of each pole of the pair of poles of the electromagnet element and the pole faces of the respective poles of the magnetic element are mutually offset in a predetermined position in space, with a gap 33 between the same electromagnet elements, The gap 32 between the same magnetic elements, and by the flow of multi-phase alternating current in the coils of the plurality of electromagnet elements, the current wave 20 of each phase is shaped as a sinusoidal drawing, so that the magnetic element and the electric β /, 罨The magnet elements interact, causing a relative movement of the thunder and the field magnet members in the moving direction in the predetermined direction to achieve the first-in-one discussion. _物 = control simplification. Here, three phases are taken as an example. Electric machine

In the second embodiment, in order to drive the field magnet member to move, in the moving direction, it is necessary to have a good-sequence-phase electromagnet element, and thus, the motor has to leave a lot of space in the moving direction to arrange the necessary electromagnets. This condition causes the motor to be occupied in the Hefang (10) empty space, and it is unfavorable to arrange multiple connections at the same time in the space in the direction of the chicken.

Figure 7 is a plan view showing the corresponding poles of the two poles of the magnetic component of the field magnet member of the multiphase brushless motor according to the third embodiment of the present invention, the pole pole face and the corresponding (four) pivot member electromagnet component. The demonstration. The fourth embodiment is a schematic diagram of a partial planar layout of a modified structure similar to the schematic diagram of the planar layout in the seventh embodiment of the present invention. The figure shows that the impurity planes 61al of the three impurity elements adjacent to each other in the direction of the movement are offset from each other by the ore in the direction of the vertical direction, and also have a skew relationship with the corresponding pole faces 51 of the corresponding electromagnet elements. The skew arrangement can suppress the change of the magnitude of the torque (4) to further reduce the interference of the torque on the motor. In the seventh and eighth figures, when the pole face edge of the electromagnet is near or away from the pole face edge of the permanent magnet, the _ interaction (four) pole face edges are skewed to each other, so that the extra action on the electromagnet and the permanent magnet The change of the torque will not be abrupt, and the phase 21 丄 333311 will reduce the degree of electricity caused by the external moment. This kind of skew arrangement can alleviate the variation of the extra torque of the electromagnet and the permanent magnet. The adjacent three electromagnet elements cause the pole faces of the adjacent three magnetic elements to be offset from each other in a direction perpendicular to the moving direction, so that the torsional moments can cancel the fluctuation of the torsional moment by canceling each other. As in the third and fourth embodiments, the addition of a two-phase current to the coils of the adjacent three electromagnet elements allows the motor to obtain a substantially constant resultant resultant force. This condition facilitates the simultaneous arrangement of a plurality of in-line and independently moving individuals in the space in the direction of movement of the motor. Fig. 9 is a view showing a partial plan layout of another modification structure of the center map of the plan layout in the eighth embodiment of the present invention. The figure shows that the pole faces 51 of the adjacent three electromagnet elements are arranged to be mutually offset perpendicular to the moving direction, and the pole faces 6iai of the adjacent two magnetic elements are arranged perpendicular to the moving direction and Corresponding pole faces of the corresponding electromagnet elements are skewed. The eighth-phase and ninth embodiments provide a multi-phase brushless motor in which the electromagnet elements adjacent to each other in the moving direction Btb are not ferromagnetically contacted with each other. (4) The interference effect is changed; and the _32 between the magnetic elements adjacent to the moving direction causes the magnetic elements of the rotation to be magnetically isolated from each other' to make the magnetic flux distribution flatter. Wherein, the plurality of sets of electromagnet elements having the paired poles arranged in the multi-directional direction are magnetically isolated from each other, and the magnetism of the electromagnet elements each having the coils is different from the electromagnet elements of the other phase-containing coils. 22 1333311 moves the track 'so that the electromagnet elements of each phase containing the coil do not interact with all of the magnetic elements. The fourth and fifth embodiments obtain the same output characteristics at the same input. Moreover, for many applications where high torque is required, space is limited in any case, and this arrangement allows the motor to provide a higher and smoother output with the same space constraints. Fig. 10 is a view showing a partial plan layout of a modified structure of a sixth embodiment of the present invention which is similar to the plan layout of the seventh embodiment. The paired pole faces of the electromagnet elements of the third embodiment are changed to such a geometric configuration mode of the sixth embodiment as an alternative to smoothing and changing the rate of change of magnetoresistance between the electromagnet elements and the magnetic elements. As exemplified in the tenth figure, one pole face HU of the pair of poles of the electromagnet element and one pole face 61 of the two poles of the magnetic element have their respective geometric arrangement patterns on their respective surfaces facing the air gap. In the sixth embodiment, the two pole faces of the pair of poles of each electromagnet element and the pole faces of the two poles of each of the magnetic elements have the same geometric arrangement pattern (not shown) on their surfaces facing the air gap, The two pole faces of the two magnetic poles of the magnetic element and the respective pole faces of the respective electromagnet elements have a different skew relationship than the previous embodiment. The skew correlation change of this different condition still has the effect of smoothing the rate of change of the torsional moment between the electromagnet element and the magnetic element, and has a different rate of change of the torsional moment from the foregoing embodiment.
