Abstract
The utility model relates to a dual-hall structure of a wheel hub motor of an electric car, which comprises a wheel hub, an end cover, a hub cover, a stator, a rotor magnetic steel, a motor shaft and a leading-out wire. The end cover and the hub cover are respectively fixed on the two ends of the wheel hub. The rotor magnetic steel and the stator are oppositely arranged inside the wheel hub. The motor shaft passes through the wheel hub. The stator is fixedly arranged on the motor shaft. The stator is provided with six hall grooves in sets of threes and symmetrically distributed on the two end surfaces of the stator. The motor shaft is provided with a threading hole. The leading-out wire passes through the threading hole and is connected with the stator. The dual-hall structure of the wheel hub motor of the electric car is provided with hall grooves in two sets of threes, so that the structure can be provided with two sets of hall elements. When one set of hall elements is damaged, the other standby set of hall elements can be utilized to enable the motor to work normally, without the need of dismounting and maintaining the motor. Thus, the dual-hall structure is in favor of the after-sale maintenance of electric cars.
Description
Technical field
The utility model relates to a kind of structural improvement of wheel hub electric motor of electric vehicle, is specifically related to the two Hall structures of a kind of wheel hub electric motor of electric vehicle, belongs to the vehicle technology field.
