Abstract

The invention discloses an outer rotor assembly and a motor. The outer rotor assembly comprises a rotor support and a plurality of magnetic steel assemblies arranged on the rotor support in a circumferential array manner, and each magnetic steel assembly comprises first magnetic steel and second magnetic steel which are oppositely arranged, wherein the first magnetic steel is located in the rotor support, and the second magnetic steel is attached to the inner wall face of the rotor support. According to the present invention, the use amount of magnetic steel can be reduced, the production cost is reduced, and the performance of the motor is improved.

Description

Technical field [0001] In addition to the rotor assembly and electric motor of the present application, specifically, a foreign rotor assembly and an electric motor are involved. Background technique [0002] The electric motor is a device that converts electrical energy into mechanical energy. It produces a rotating magnetic field using a power coil (that is, the stator winding) and acts on the rotor (such as a rock closing aluminum frame or inline magnet) to form a magnetoal power rotation torque. [0003] The motor typically includes an inner rotor motor and an outer rotor motor, and the inner rotor motor is a stator, and the rotor rotation generates power. The outer rotor motor is the opposite structure, the stator is in the middle of the motor, and the rotor is outside. The outer rotor motor has the characteristics of high efficiency, low noise, light weight, compact structure, convenient installation and maintenance, and extensive applications in the field of electric vehic...
