Description
Technical field
The invention provides a kind of stealthy magnetic pole rare earth permanent magnet drive motors used for electric vehicle, belong to electric motor of automobile technical field of electric appliances.
Background technology
Current and the matching used drive motors of electric automobile mostly adopts the direct current machine with carbon brush and mechanical commutator, although DC motor structure is simple, controllability is high, speed-regulating range width, control circuit is relatively simple, cost is lower, but because the magnetic field of direct-drive motor is produced by electric excitation winding, power consumption is many, power output is little, in addition owing to having carbon brush and mechanical commutator, not only limited the raising of drive motors overload capacity and speed, if long-play, often maintenance be certainly will need and carbon brush and commutator changed, therefore direct current machine energy consumption is large, failure rate is high, its serviceability needs further improvement.
Summary of the invention
The object of this invention is to provide one and can overcome above-mentioned defect, the magnetic field of drive motors is provided by permanent-magnet steel, few without electric excitation winding, power consumption, there is no the used for electric vehicle stealthy magnetic pole rare earth permanent magnet drive motors of carbon brush and mechanical commutator, failure rate is low, its technology contents is:
The used for electric vehicle stealthy magnetic pole rare earth permanent magnet drive motors being comprised of front end housing, rear end cap, casing, rotor, stator, is characterized in that: drive motors rotor is stealthy magnetic pole rare-earth permanent magnet rotor;
Stealthy magnetic pole rare-earth permanent magnet rotor is comprised of garden arc permanent-magnet steel, rotor core, pole shoe, screw, axle, on rotor core, be evenly equipped with the long salient pole of even number and the short salient pole of even number, long salient pole and short salient pole space, long salient pole is than the long 4mm of short salient pole, intrados is S Ji garden arc permanent-magnet steel and by screw, is fixed in the external arc of the short salient pole of rotor core by pole shoe, the thickness of garden arc permanent-magnet steel and the thickness of pole shoe are 2mm, and rotor core is fixed on axle.
operation principle:when permanent magnet drive motor passes into by three-phase inverter after the three-phase alternating current of pulse-width modulation, drive motors stator produces a space rotating magnetic field, the magnetic field interaction that it and rotor permanent magnet steel produce, rotor produces the rotating torques consistent with stator winding rotating magnetic field direction, drive motors p-m rotor is rotated, and then drive electric automobile operation.
The present invention compared with prior art, rotor core periphery is evenly equipped with long salient pole and the short salient pole of even number space, intrados is S Ji garden arc permanent-magnet steel and is fixed in the external arc of short salient pole, pressing close to the S utmost point of the garden arc permanent-magnet steel intrados of short salient pole guides on long salient pole exterior arc surface by rotor core, form the N utmost point, the extremely spaced stealthy pole wheel of S, two polarity of garden arc permanent-magnet steel are all fully used, compact conformation, reliable operation.
