Abstract

The invention discloses a motor, a rotor and an installation method of the rotor. The rotor comprises an inner rotor iron core (1) and an outer rotor iron core (2), wherein a plurality of inner rotor bosses (11) distributed uniformly are arranged on the outer wall of the inner rotor iron core (1), first positioning holes (12) are formed in the inner rotor bosses (11), outer rotor bosses (21) are arranged on the inner wall of the outer rotor iron core (2) and are in one-to-one correspondence to the inner rotor bosses (11), the outer rotor bosses (21) and the inner rotor bosses (11) are staggered in an axial direction, and second positioning holes (22) are formed in the outer rotor bosses (21) and arranged corresponding to the first positioning holes. With the rotor provided by the invention, the inner rotor bosses and the outer rotor bosses are prevented from being mismatched, the rotor dynamic balance performance is ensured, and the running reliability of the rotor is ensured.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a motor, a rotor and a method for installing the rotor. Background technique [0002] In order to weaken the torque ripple of the motor and improve the sound quality of the load, the damping rotor uses rubber and other elastic buffer materials to inject the inner rotor core and the outer rotor core into one body, and reduces the impact of load torque ripple on the load through the buffer material. impact, thereby improving load sound quality. [0003] At present, the vibration damping structure cannot guarantee the accurate alignment of the inner rotor core and the outer rotor core during injection molding. During the injection process, the inner and outer rotor cores are prone to misalignment, resulting in poor dynamic balance of the rotor and poor reliability. reduce. [0004] Therefore, how to avoid misalignment and ensure the operational reliability of the rotor is ...
