Problems solved by technology

[0002] The rotor in the related art will generate torque pulsation during operation, which will affect the working performance of the rotor. The rotor needs to be equipped with structural parts such as rubber parts or injection molded parts with vibration damping functions, resulting in a complicated structure of the rotor. The production efficiency is low, and the production cost of the rotor is high

Abstract

The invention discloses a rotor and a motor thereof, the rotor includes: an iron core, the iron core includes a first punching piece and a second punching piece, the first punching piece and the second punching piece are The iron cores are stacked axially, and the first punching sheet includes an inner punching sheet, an outer punching sheet located outside the inner punching sheet, and a connecting portion connecting the inner punching sheet and the outer punching sheet, At least a part of the connecting part is an elastic member for reducing the influence of the torque pulsation on the outer punch on the inner punch, and the iron core is provided with a shaft hole; the rotating shaft is fitted on the inner punch inside the shaft hole. The rotor according to the embodiment of the present invention has the advantages of simple structure, low cost, good vibration damping effect and the like.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a rotor and a motor with the rotor. Background technique [0002] The rotor in the related art will generate torque pulsation during operation, which will affect the working performance of the rotor. The rotor needs to be equipped with structural parts such as rubber parts or injection molded parts with vibration damping functions, resulting in a complicated structure of the rotor. The production efficiency is low, and the production cost of the rotor is high. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a rotor, which has the advantages of simple structure, low cost and good vibration damping effect. [0004] The invention also proposes an electric machine with the rotor. [0005] In order to achieve the above object, a rotor is p...
