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 current generator is produced by electrical excitation winding, power consumption is many, output is little, additionally, due to there is carbon brush and machine
Tool diverter, not only limits the raising of direct current generator overload capacity and speed, and if long-play, certainly will need through
Often safeguarding and change carbon brush and diverter, therefore direct current generator energy consumption is big, fault rate is high, and its serviceability awaits changing further
Enter.
Summary of the invention
It is an object of the invention to provide one and can overcome drawbacks described above, the magnetic field of hub driven motor is provided by permanent-magnet steel,
