Embodiment
Below in conjunction with accompanying drawing, explain technical scheme of the present invention.
According to shown in Figure 3, the invention has the advantages that: the magnetic flux that flows through each permanent magnet is except that the magnetic flux that self produces, also has magnetic flux from two permanent magnets on its adjacent both sides each half, thereby make the magnetic flux that flows through each permanent magnet increase one times, also make the magnetic flux that flows through magnetic conductor and solenoid increase one times, and motor torque and main magnetic flux (or magnetic flux density) are proportional, thereby have improved motor efficiency significantly.
Shown in Fig. 1,2,8,9, the invention is characterized in: 1, solenoid winding quantity is half of permanent magnet number; Each winding interior loop is arranged as shown in Figure 8, parallel being staggered between the coil, nearly half the coil (as the electromagnetic wire of the left side vertical line direction of loop A, B, C, D among Fig. 8) of each winding is over against the N utmost point of permanent magnet, and near in addition half coil (as the electromagnetic wire of the right vertical line direction of loop A, B, C, D among Fig. 8) is over against the S utmost point of permanent magnet; The coil number is decided by factors such as magnetic conductor size, motor power (output)s, there is not specific (special) requirements, and general DC Brushless Motor is different, its number has specific (special) requirements, manufacturing process is higher relatively, and difficulty is bigger, and the relative requirement of manufacturing process of the present invention is lower, make easily, reduced manufacturing cost.2, electromotor control circuit is that example describes with the loop A; Place two Hall element HA1, HA2 respectively at the loop A two ends, its position just is the N utmost point of HA1 over against permanent magnet, and HA2 is over against the S utmost point of permanent magnet; Hall element is after energized, and it produces signal and is controlled by epitrochanterian permanent magnet, needn't add the control magnet in addition; Utilize Hall element generation signal controlling power switch pipe conducting or close power switch pipe available horsepower switch triode, also available controllable silicon diode and other power switch pipe; During over against the N utmost point of permanent magnet, HA1 produces a forward voltage signal, makes K1 and K3 conducting at HA1, and HA2 is over against the S utmost point of permanent magnet, and HA2 does not have the forward voltage signal and produces K2 and not conducting of K4, there is not electric current to flow through, be equivalent to open circuit, electric current flows through K1 from dc power anode like this, enters the A1 end of loop A, flow out from the A2 end, flow through K3, enter power cathode, produce moment this moment and impel rotor to counterclockwise rotating; After rotor turned over the A1 position, HA1 was over against the S utmost point of permanent magnet, and HA2 is over against the N utmost point of permanent magnet, in like manner, Hall element HA2 produces a forward voltage signal, makes K2 and K4 conducting, and HA1 is over against the S utmost point of permanent magnet, and HA1 does not have the forward voltage signal and produces K1 and not conducting of K3, be equivalent to open circuit, electric current flows through K2 from dc power anode like this, enters the A2 end of loop A, flow out from the A1 end, flow through K4, enter power cathode, produce moment this moment and impel rotor to continue to counterclockwise rotating; To with loop A parallel coils B, C, D or the like, its control principle is identical with A, like this, no matter permanent magnet forwards what direction (or when starting) to, electric current is controlled through control circuit, its direction is to make the direction in the magnetic field that electric current produces vertical with the permanent magnet magnetic field direction all the time, and the torque of generation makes rotor rotate to same direction at any time; As previously mentioned, motor efficiency is very high, remove and need a determining deviation (the middle non-magnetizer of placing between the adjacent permanent magnet, have only very a spot of magnetic line of force to pass through therebetween) outside, produce magnetic field interaction generation torque at all the other position magnetic field of permanent magnet and coil current, make motor efficiency up to about 90%; As previously mentioned, the motor starting torque is very big, when starting, deducts power switch tube voltage drop (this voltage drop is very little), and the effective voltage that acts on the coil approximates supply voltage; And when rotating, because the coil cutting permanent magnet magnetic line of force can produce reverse induced electromotive force, effective voltage is that supply voltage deducts voltage drop on induced electromotive force and the power switch pipe, the effective voltage that acts on the coil has reduced, and torque this moment is less than the torque of when starting.3, can make rotor counter-rotating by following way: first kind, in Fig. 9, the loop A wiring is inverted, in control circuit, meet the A1 place and change into and meet A2, meet the A2 place and change into and meet A1, all the other coils are the method reconfiguration according to this, all the other element connection and invariant positions; Second kind, in loop A, the invariant position of Hall element, with signal controlling K2 and the K4 of HA1, with signal controlling K1 and the K3 of HA2, all the other coils are equally changed; As previously mentioned, in control circuit, increase corresponding switch, just can control rotor and impeller direction of rotation easily, twitched fluid flow direction thereby can control easily.4, turn to difference to two and fluid flow direction is identical, power is identical product of the present invention is fixed together stator by fixed part, the torque of two stators is cancelled out each other, not only can reduce vibrations and noise, and not need product of the present invention is fixed on other mounting article.5, rotor speed can reach very high, and the weight of rotating speed and supply voltage, load, rotor and impeller and size are also relevant with air drag, sound barrier or the like factor in the time of in air, and rotating speed can be up to more than 10000 rev/mins in theory.
Because the present invention is placed in the fluid of being twitched usually, so need good sealing, sealing 11 places in Fig. 2, position, i.e. place, slit sealing between stator end and rotor magnetic conductor end, both available mechanical seal, also available magnetic fluid sealing, mechanical seal is owing to friction is easy to generate heat, and magnetic fluid sealing produces heat seldom, and sealing property is also fine.
In stator magnetizer owing to changes of magnetic field produces heat, in solenoid, there is electric current to flow through also and can produces heat, these two kinds of origin of heat are the main heats that produce among the present invention, what the present invention adopted is the inner loop type of cooling of external cooling water pipe: the metal tube of using good heat conductivity is as cooling water pipe, the cooling water pipe two ends are inserted from end, stator two ends, and the space is connected between stator and the rotor, around stator a plurality of cooling water pipes is installed, as shown in Fig. 1,2; Some slanted bars (as shown in fig. 1, its rising height is significantly smaller than gap width between stator and the rotor) of projection are slightly being arranged on the rotor non-magnetizer; Be full of cooling fluid or cold gas in gap between rotor and stator and the cooling water pipe, when rotor rotates, because the effect of slanted bar on the non-magnetizer, make cooling fluid or cold gas flow into cooling water pipe one end, outwards dispel the heat through cooling water pipe, flow into gap between stator and the rotor, because protecting sheathing is not airtight (as shown in fig. 1) from the other end, so cooling water pipe can have thermolysis preferably being dispelled the heat by in the fluid of twitching; If San Re efficient does not reach requirement like this, can also cool off cooling water pipe from the outside, to strengthen radiating effect.Twitched fluid when flowing through pump, contacted, also can be taken away a part of heat with parts such as rotor magnetic conductor and impeller blades.
The outside movement-less part of the present invention generally can not damage organism in water as the power of power-driven vessel (or ship) time.But the impeller high speed rotating is arranged in the rotor cylinder, biology may damage in the liquid to flowing through, the present invention has added a separation net, separation net is made of the higher hard lines (as bonding jumper) of intensity, its two ends are connected with the stator two ends, like this, pass through, can not hurt greater than the intermediate void that the biology of grid can form when impeller rotates.If an end end that flows at fluid adds separation net, the present invention also can be without the internal insulation net.Therefore the present invention generally can convection cell in biology damage, thereby play the effect of environmental protection.
The present invention will consider the resistance that external form of the present invention causes in the power time spent as movable machineries such as ship or ships, for reducing resistance, can respectively add a circle hard bullet (shown among Fig. 2 12) around stator at both ends.
The present invention both can be used as suction pump and had used, and the power that also can be used as movable machineries such as ship, submarine uses, can also use as hydraulic giant that produces high pressure, high-speed jet or air gun, or the like, purposes is comparatively extensive; The present invention is simple in structure, compares with general pump, has reduced a lot of parts, has alleviated weight, and also time and manpower is saved, saves manufacturing cost at least more than 20%; Owing to has reduced moving component, and saved electric power, and noise is also lower more than 20%.Therefore, the present invention has great practical value and vast market prospect.
