The utility model can adopt f-w-d, back-wheel drive or front and back four wheel drive multiple choices.Under to starting and the less demanding situation of low-speed performance, can adopt the mode of frequency converter frequency conversion to realize the speed change adjusting of electrocar separately.
When the utility model is implemented, need the problem of explanation:
1, speed change is regulated and frequency converter
Under the general situation, frequency control can be satisfied the speed governing requirement of electronlmobil fully, because automobile-used frequency converter adopts effectively compensate function when low frequency is controlled, as voltage compensation.The utility model adopts frequency conversion to realize the speed change adjusting of electronlmobil in conjunction with the mode of motor pole-changing, its principle be when exchanging many magnetic poles of threephase asynchronous machine slow speed of revolution during than high rotating speed torque bigger, when electrocar starting or heavy-duty low-speed travel, wheel hub motor is transferred to many magnetic poles low-speed running, frequency converter need not transfer to low frequency, can reduce the decay of power, make the starting of electrocar and heavy-duty low-speed performance better.Wheel hub motor adopts high rotation speed operation during cruising.
The interior supporting inverter that has of common automobile-used frequency converter does not need to establish separately inverter.
2, the speed discrepancy between the wheel
When the relation between phase asynchronous alternating current dynamo rotating speed and the load is the motor load increase, rotating speed can descend relatively, can rise relatively during load reduction, with this principle, but the just rotating speed difference between the automatic compensation wheel, for example: when the vehicle wheel rotational speed in left side is lower than right side wheels, the load meeting of its wheel hub motor is corresponding to alleviate automatic raising rotating speed, increase the weight of automatic rev down and the wheel hub motor load meeting on right side is corresponding, until reaching balance, the relation of front and back wheel also is like this.If the rotating speed difference is excessive, certainly will cause the overload of wheel hub motor, when turning to as wide-angle, this situation wheel hub motor is laterally implemented automatic rotating speed compensation, to improve rotating speed.
3, the overload of wheel hub motor
Employing is carried out maximum running current limiting protecting to wheel hub motor, and overload time surpasses certain limit and is provided with signal caution and overload power-off protection.
