Abstract
The invention provides a surface-mounted radial and embedded tangential permanent magnet steel drive motor, and belongs to the technical field of electric automobile motors and appliances. The drive motor is composed of a front end cover, a rear end cover, a case, a rotor, and a stator. The rotor of the drive motor is a permanent magnet rotor with a composite magnetic field which is composed of a radial magnetic field and a tangential magnetic field. The magnetic field is strong, and the power density is high. The structure is a rotor magnetic bypass structure, which can effectively prevent the problem that the permanent magnet steel pieces generate irreversible demagnetization under the armature reaction effect of impact current and ensure that the permanent magnet steel pieces do not lose magnetism. No electric excitation winding is needed, and there is less power consumption. There is neither carbon brush nor mechanical commutator, and the failure rate is low. The drive motor has a compact structure, and works reliably.

Background technology
Current and electric automobile matching used driving motor mostly uses the unidirectional current with carbon brush and mechanical commutator
Machine, although DC motor structure is simple, controllability is high, speed-regulating range width, control circuit are relatively easy, cost is relatively low, but
Owing to the magnetic field of direct-drive motor is produced by electrical excitation winding, power consumption is many, delivery efficiency is low, additionally, due to there is carbon brush
And mechanical commutator, not only limit driving motor overload ability and the raising of speed, and if long-play, Shi Bixu
Often to safeguard and to change carbon brush and diverter, therefore direct current generator energy consumption is big, fault rate is high, and its serviceability awaits into one
Step is improved.
Summary of the invention
It is an object of the invention to provide one and can overcome drawbacks described above, drive the magnetic field of motor to be provided by permanent-magnet steel, it is not necessary to

Adjacent peariform slot does not connects every magnetic air gap, is provided with and runs through rotor core thickness in the middle of the outer end of adjacent two radial direction rectangular channels
Circular hole, the center of circle of multiple circular holes, all on same circumference, does not connects between outer end and the cylindrical of rotor core of circular hole, circular hole
Diameter is more than the diameter of screw, and iron rivet is through the circular hole on rotor core fixed rotor iron core, by rectangle permanent-magnet steel by phase
The N pole of adjacent two panels rectangle permanent-magnet steel and N extremely relatively, S pole and S extremely relative to mode be sequentially arranged in radial direction rectangular channel, then
Tile permanent-magnet steel is pressed the identical mode of polarity that the polarity of the lateral surface rectangle permanent-magnet steel adjacent with two panels formed and by screw
Being sequentially fixed on the iron rivet in rotor core by pole shoe, rotor core is fitted on axle.
Operation principle: when permanent magnet drive motor is passed through by three-phase inverter after the three-phase alternating current of pulsewidth modulation, drives
Motor stator produces a space rotating magnetic field, and it is magnetic field interaction produced by with rotor permanent magnet steel, and rotor produces with fixed
The rotating torques that sub-winding rotating magnetic field direction is consistent, makes driving motor permanent magnetic rotor rotate, and then drives electric automobile to run.
Compared with prior art, tile magnet steel is fixed on the cylindrical of rotor core the present invention, rectangle permanent-magnet steel is embedded in
