During the invention process, 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 all adopts effectively compensate function when low frequency, as voltage compensation, can satisfy the requirement of starting and low speed driving.The present invention adopts frequency conversion to realize the speed change adjusting of electronlmobil in conjunction with the mode of motor pole-changing, its principle is to exchange threephase asynchronous machine, torque is bigger during many magnetic poles slow speed of revolution, when electronlmobil starting or low speed driving, less axle shaft motor is adjusted to the running of many magnetic poles slow speed of revolution, and frequency converter need not be transferred to low frequency.Can reduce the decay of power, make the starting of electrocar and low-speed performance better.Wheel hub motor adopts the normal speed running 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 was lower than right side wheels, corresponding the alleviating of load meeting of its left side wheel hub motor just can be improved rotating speed automatically, and corresponding the increasing the weight of of wheel hub motor load meeting on right side, also rev down automatically up to reaching balance, also is like this between the front and back wheel.If the rotating speed difference is excessive, certainly will cause the overload of inboard motor, when turning to as wide-angle, this situation wheel is to the inside 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.
