Control for convenience, in specific embodiments of the invention, described double-stator permanent magnet synchronous generator-electric motor also comprises the control device (not shown), described control device circuit respectively connects described first coil windings 4 and described second coil windings 7.
Operation principle of the present invention is: at first control device realizes that by the electronic switch power device battery is to the 4 energising actions of first coil windings, the rotating magnetic field that the stationary magnetic field that first permanent magnet 5 produces and first coil windings 4 produce interacts, driving rotor 2 rotates with synchronous speed, in this simultaneously, second coil windings 7 in the stationary magnetic field cutting external stator 6 that second permanent magnet 8 produces, because the principle of the law of electromagnetic induction, in second coil windings 7, produced three-phase current, and then rotating magnetic field and induced electromotive force have been produced, when rotor 2 rotating speeds greater than the agreement base value (being that induced electromotive force is greater than cell voltage) time, second coil windings, 7 feeds are given battery, carry out motoring condition in order to first coil windings 4 that continues supply internal stator 3, as the drive unit in the electric automobile.If think electronic or independent feed separately, only need to realize getting final product by the electronic power switch device in the control device.
Therefore, the invention provides the frame mode of a kind of feed simultaneously and electronic electric vehicle permagnetic synchronous motor.Because motor has external stator 6 and internal stator 3, therefore two cover magnetic circuits are arranged, for realize second coil windings 7 only with second permanent magnet, 8 linkages, first coil windings 4 only with first permanent magnet, 5 linkages, reduce linkage and brow leakage between them, need between them in addition every the magnetic magnetic stripe with every the magnetic magnetic patch, in order to improve the utilization ratio of permanent magnet.Secondly, according to different power grades, can adopt different cooling schemes, permagnetic synchronous motor as used for electric vehicle, usually require its power density bigger, therefore the existence in water route all should be arranged on machine shaft 1 and casing (not shown), and concrete condition need be made a concrete analysis of, up to satisfying the heat dissipation design requirement.Once more, this motor needs jockey that non-contacting rotor 2 and machine shaft 1 are coupled together, and material is used non-magnet material.At last, because the internal diameter of external stator 6 and the external diameter of internal stator 3 differ greatly, so internal stator 3 can adopt fractional-slot, reduces the torque ripple situation.All electric motor cars or industrially all can use this kind structure especially need the electric motor car industry of charging separately.
The present invention is by being provided with two cover stators: one be feed with and one be electronic usefulness, and in rotor 2 supporting two cover permanent magnets, between them every magnetic treatment, electronic and feed of while when making the motor operation.The present invention has following beneficial effect:
If 1, automobile needs feed and electronic simultaneously in the prior art, then need two cover electric machines, just and the present invention has only used a covering device to realize that electronic and feed is dual-purpose, thereby saved the installing space of electric automobile.
2, can realize the operation of electric automobile limit, the limit charges the battery, and having saved needs the specially charging interval.
3, this motor can be provided with inside and outside two cover water routes, and radiating effect is more obvious, can improve the power grade of motor.
To sum up, double-stator permanent magnet synchronous generator of the present invention-electric motor design is unique ingenious, can be in the process that the driving electric motor car travels, and feed condition simultaneously generates electricity, make and the problem that to worry operating range and F-Zero be suitable for large-scale promotion application.
