Abstract
Disclosed is a motor rotor, comprising a rotor core and two end rings respectively arranged at two ends of the rotor core, wherein the end rings are composed of a main end ring fixedly connected with the rotor core and an auxiliary end ring cooperating with the main end ring via concave-convex cooperation; and the assembling structure of the main end ring and the auxiliary end ring is a circular ring structure. According to the technical scheme of the utility model, the main end ring is an asymmetric end ring. After the magnet is installed in the magnetic steel groove, the auxiliary end ring and the main end ring are made to cooperate in a concave-convex manner. As the assembling structure of the main end ring and the auxiliary end ring is a circular ring structure and is a symmetric structure relative to the axle center of the rotor, the motor starting capability and the rotation stability of the rotor during the starting process are improved. The auxiliary end ring prevents the magnet from slipping from the magnetic steel groove, thereby making it unnecessary to arrange a baffle plate, reducing the additional devices of the motor rotor, and decreasing the weight of the motor rotor. Therefore, the energy consumption amount of the motor driving the motor rotor is also reduced. The utility model also provides a motor equipped with the motor rotor.
