Title: MOTOR ASSEMBLING METHOD, MOTOR ROTOR, AND MOTOR
Abstract:
Disclosed are a motor rotor, motor, and motor assembling method. The motor assembling method comprises a rotor assembling process, the rotor assembling process comprises: sleeving elastic rings (3) onto shaft shoulders (12) on two sides of a magnet ring installation position (11) (102); sleeving a magnet ring (4) into the magnet ring installation position (11) such that the magnet ring (4) is pressed against the elastic rings (3) (104); and installing balance rings (2) on two sides of the magnet ring (4) respectively (106). Due to the elasticity of the elastic rings (3), the magnetic attraction of the magnet ring (4) in the radial direction is canceled such that the magnet ring (4) cannot move in the radial direction, thus enabling a small concentricity deviation between the magnet ring (4) and an axis (1), that is, central alignment, reducing the concentricity deviation and increasing the rotational stability of the motor.
