Abstract

The invention provides a rotor structure and a motor, and the rotor structure comprises a body structure which comprises an outer iron core, a magnet, and a supporting frame, wherein the supporting frame is provided with a through hole and a plurality of first connecting holes formed in the direction surrounding the preset axis at intervals, and the plurality of first connecting holes, the outer iron core and the magnet are arranged at intervals; an inner iron core used for being connected with a shaft of the motor, wherein the inner iron core is installed in the through hole and is spaced from the body structure, and the inner iron core is provided with a plurality of second connecting holes which are formed at intervals in the direction surrounding the preset axis; a damping piece which is made of a deformable material, and comprises a damping part located in a gap between the inner iron core and the body structure, wherein the damping piece comprises a first connecting part and a second connecting part, the first connecting part is arranged in the first connecting hole in a penetrating mode, and the second connecting part is arranged in the second connecting hole in a penetrating mode. According to the rotor structure, the problem that the damping effect and the structural strength of a rotor structure in the prior art are difficult to consider is solved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor structure and a motor. Background technique [0002] During the working process of permanent magnet synchronous motor, it is easy to cause motor vibration due to torque ripple. [0003] In the motor in the related art, shock-absorbing rubber is arranged between the inner iron core and the outer iron core of the rotor structure to reduce torque ripple output vibration, thereby reducing the noise of the motor. In the motor with structural design, the connection between the inner iron core and the outer iron core relies on shock-absorbing rubber, which makes it difficult to ensure the stability of the connection between the inner iron core and the outer iron core, resulting in a poor ability of the motor rotor structure to withstand shear stress , which has a great impact on the structural strength of the motor rotor.
