Rectangular teeth or T shape tooth that described armature core 4 circumferential surfaces are provided with, its along the teeth directional of X-X ' line and Y-Y ' line or groove to, can be straight shape tooth (groove) along Y-axis, also can be to tilt less than the oblique tooth (groove) of 15 ° of mechanical angles along Y-axis.The described wire casing that is arranged between armature core circumferential surface tooth and the tooth, its cross section along rotor shaft direction exists two corners (rectangular teeth) or four corners (T shape tooth), this corner can be 90 ° of right angles or angle of collimation, fillet preferably, the radian of the radian of fillet and winding coil conductor cross-section is all optimum value mutually.This designing requirement adapts around the structure that tooth 6 connects up continuously in wire casing 5 with winding coil lead provided by the invention, and winding wire forms around the tooth wiring and produces the major reason that magnetic swashs resonance when coil windings is rotor and armature core relative motion.
The wire structures of conventional armature iron core winding coil is characterized as: the effect of wire casing is used to place winding coil in groups, the series connection of the coil of different slots is connected to the winding of same phase by connecting line.Winding construction provided by the invention is characterized as: the effect of wire casing is not the winding coil that is used to place in groups, but as passage around the tooth wiring, the lead of winding coil connects up formation around tooth trace circle winding continuously around n tooth in wire casing, n is the positive integer less than m.In the relative motion of tooth trace circle and magnetic pole, effectively cutting magnetic line is around the line segment of tooth trace circle in groove.This winding coil can be regarded the solenoid of an equivalent deformation as, and tooth becomes the built-in iron core of this solenoid.When the relative armature core rotating operation of rotor of P permanent-magnet pole 7 of band, be inspired stronger induced current around the tooth trace circle, so the tooth surface of motor when moving becomes a dynamic little magnetic pole.Because around the little magnetic pole of tooth surface that the tooth trace circle is inducted when the rotor permanent-magnet pole is moved relatively, can be in operation influences the variation of the Distribution of Magnetic Field on rotor permanent-magnet pole surface conversely.This Distribution of Magnetic Field rate of change is big more, and the induced current around the tooth trace circle in the armature core is big more, and little magnetic pole field intensity that tooth surface excites is big more, will further aggravate the variation rate of magnetic flux in magnetic space in the motor relative the in service of rotor.The dynamic chain action and reaction of this rotor and stator, afterwards moment enters the sharp mutually resonance condition in a kind of magnetic field in the operation beginning to make motor, should swash resonance condition mutually owing to the magnetic saturation value that is restricted in magnetic material, thereby enter dynamic equilibrium rapidly, formed the sharp resonant tank of the metastable magnetic in magnetic space in the motor, made motor be able in the sharp mutually resonance equilibrium state in magnetic field, move.Above-mentioned this magnetic swashs the variation rate of magnetic flux that resonant tank has been strengthened magnetic space in the motor greatly, therefore use this magnetic to swash the motor that resonance principle is produced, can obtain the energy more much higher, use the motor of this principle and foundation structure, can be referred to as the magnetically excited resonant motor than conventional motor.
Above-described motor be in operation rotor permanent-magnet pole magnetic field and armature core around the little magnetic pole and magnetic field of tooth swash the resonance degree mutually, count the population size of P and armature core number of teeth m with rotor magnetic pole and structure that magnetic pole is arranged closely related.When rotor speed one timing, P is big more, and m is big more, and rotor magnetic pole and armature core influencing each other between the little magnetic pole of tooth trace circle is big more, therefore the magnetic pole P of big number more helps dynamically swashing mutually of primary and moving magnetisation field in the motor, and the magnetic pole arrangement is selected more to help magnetic to swash resonance formation when suitable.In the actual design of motor, number of teeth m be provided with can with number of magnetic poles P in rotor permanent-magnet component benchmark each other, m=1-9P, and P is greater than 16 even numbers less than m.For example select m=120, P=40.
A kind of rotor 2 provided by the invention is different with conventional motor towards magnetic pole 7 arrangements on armature core 4 surfaces, the rotor NS magnetic pole of conventional motor P=4 is alternately arranged and is seen accompanying drawing 1 and accompanying drawing 2, characteristics are that the spacing between the N utmost point and the S utmost point are alternately arranged is not done special provision, and the magnetic flux period profile schematic diagram of its armature core 4 is seen accompanying drawing 7.The rotor field structure section distribution map that a kind of number of magnetic poles provided by the invention is P, along X-X ' and Y-Y ' line expanded view and armature core magnetic flux period profile figure thereof shown in accompanying drawing 8-a, b and c.P=60 in the diagram, its structure is: P magnetic pole alternately arranged by the N utmost point and the S utmost point, but specific between the magnetic pole be space D, the range of choice of D is a benchmark with armature core 4 adjacent two space width W, D=0.3-0.8W.
The armature core 4 of circumferential surface band rectangular teeth of the present invention or T shape tooth both had been applicable to external rotor electric machine, also was applicable to inner rotor motor.When making an inner rotor motor, the rectangular teeth of armature core 4 or T shape tooth are arranged on the inner circumferential surface of armature core in the face of rotor 2, shown in accompanying drawing 8-a; The rectangular teeth of external rotor electric machine or T shape tooth are arranged on the external peripheral surface of armature core 4 in the face of rotor 2, as shown in Figure 9.
Armature core and P the rotor that magnetic pole NS alternate intervals is arranged of adopting a kind of circumferential surface band rectangular teeth provided by the invention or T shape tooth, winding coil to connect up continuously around tooth, the winding coil of the same number of turn can obtain bigger induced electromotive force with the relative rotor magnetic pole motion of phase same rate, or can make rotor obtain bigger moment of torsion under same electric energy input condition.Therefore, utilization the present invention can obtain bigger output energy in the motor of equal volume, weight.Because winding coil characteristics of the present invention are to be big number around continuous wiring of tooth and number of teeth m, bring diversified thus around the tooth wire structures, for example both can form winding along armature core circumferential surface wiring, also can be after tooth forms coil several of more different teeth be formed same phase winding around the series connection of tooth trace circle around tooth.
The simplest a kind of single-phase winding of the present invention around tooth along the continuous wire structures of armature core 4 circumference, as shown in figure 10, expression be the expansion diagrammatic sketch of this winding along X-X ' line and Y-Y ' line.The characteristics that winding wire connects up continuously around tooth 6 are around tooth 1/2 circle, oppositely enclose around tooth 1/2 along next tooth, when winding conducting wire ring armature core 4 circumference around full when a week getting back to the initial point groove, can continue around the 2nd, 3 ... week, till expiring line or having reached designed coil turn, the proportional relation of coil turn and induced electromotive force is identical with the multiplication principle of conventional motor up to the wire casing mouth.
A kind of two phase windings provided by the invention are around the continuous wiring method expanded view of tooth 6 along armature core 4 circumference, as shown in figure 11, characteristics are: winding wire around tooth 3/4 circle, two grooves of being separated by (or 3 teeth) more in the same way around tooth 3/4 circle along the armature core 4 circumferential surfaces formation coil windings that connects up continuously.
A kind of three phase windings provided by the invention are around the continuous wiring method expanded view of tooth 6 along armature core 4 circumference, as shown in figure 12, characteristics are: winding wire around tooth 3/4 circle, 4 grooves of being separated by (or 5 teeth) more in the same way around tooth 3/4 circle along the armature core 4 circumferential surfaces formation coil windings that connects up continuously.So analogize the coil windings of forming polyphase machine.
Described winding coil structure also comprises a kind of two, three or k root wire-wound group around the continuous wire structures of tooth along armature core 4 circumference, and its expanded view is shown in Figure 13,14.Wherein two-wire is parallel along the continuous wire structures expanded view of armature core 4 circumferential surfaces around the single-phase winding of tooth 6 formation, as shown in figure 13; Two-wire is parallel along the continuous wire structures expanded view of armature core 4 circumferential surfaces around tooth 6 formation two-phase windings, as shown in figure 14, so analogizes the parallel polyphase winding winding around tooth of formation k line, and k is generally the positive integer of 2-30.
Winding coil of the present invention comprises that also another kind of wherein form around the L circle around certain tooth 6 should be around the tooth trace circle for conductor loop around tooth trace circle series connection winding construction as shown in figure 15, with several of G the tooth of being separated by equally around the tooth trace circle same phase coil winding of formation of connecting.This series coil winding construction is identical with the principle that the wire casing coil series connection of conventional motor forms winding, so analogizes the composition polyphase windings.Described L=1-200, G are 0 or less than the positive integer of m.
The invention has the advantages that: because the rotor permanent magnetic field of motor of the present invention and the mutually sharp resonance effect that excites magnetic field around the tooth trace circle, its output energy is generally big more than 30% than conventional motor.Simultaneously, because armature core 4 circumferential surface number of teeth m and the N, the S alternating poles that cooperate magnetic to swash resonance are counted P and are exceeded one or two order of magnitude more than conventional motor, therefore use generator that the present invention makes under same rotor speed situation, what export at the coil windings two ends is the high-frequency alternating current that the conventional motor of frequency ratio exceeds one or two order of magnitude, and this output current frequency feature is different with the generator in 50 weeks of conventional output.For example as number of magnetic poles P=60, when motor speed is 3000 rev/mins (50 revolutions per seconds), output be that frequency is the alternating current in 1500 weeks, thereby effectively adapt to the demand of a lot of applications to high-frequency current and special waveform electric current.When practical such as non-application high-frequency alternating current, can be by circuit built-in or that join outward, be transformed to the electric current of practical required direct current, square wave, sine wave or other optional frequency and waveform by conventional electrical circuit methods such as rectification, filtering, frequency conversions, reduce the instrumentation cost of attaching troops to a unit of the unconventional 50 all alternating currents of acquisition.
Compare with the motor of conventional 50 all frequencies, because the built-in rotor magnetic pole of motor of the present invention counts P and armature core number of teeth T all exceeds one or two order of magnitude, can form by the different structure of winding wiring than the more colourful PHASE DISTRIBUTION of conventional motor, for conventional electrical circuit control motor operating state provides more simple and practical numerous controlling schemes, this Electric Machine Control direction is the focus of the technology of electric motor car development in recent years.
