Abstract

The invention provides a rotor and a motor. The rotor comprises an iron core and a limiting structure, the iron core is formed by stacking a plurality of punching sheets, the iron core is provided with an insertion hole penetrating through the plurality of punching sheets, the maximum size of the insertion hole in the radial direction of the iron core is A, the minimum size of the insertion hole in the circumferential direction of the iron core is B, and A is smaller than B; the limiting structure comprises a plug connector, and the plug connector is arranged in the insertion hole in a penetrating mode; and on the radial cross section of the iron core, the shape of the plug connector is matched with the shape of the jack. By the adoption of the scheme, the insertion hole in the iron core is arranged to be of the structure with the radial size smaller than the circumferential size, the cross section of the plug connector of the limiting structure is arranged to be of the structure matched with the shape of the insertion hole, and the scheme can also be understood that the insertion hole and the plug connector are both made flat, so that occupation of the insertion hole and the insertion piece on the radial size of the iron core is reduced, and the rotor with a small punching sheet area can be limited by using the plug connector. Compared with glue fixation, the manufacturing process difficulty of the rotor is reduced, and the structural reliability is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotor and a motor. Background technique [0002] The motor is mainly composed of a stator and a rotor. The rotor includes an iron core and accessories. The accessories mainly include rivets and counterweights. Among them, the iron core is formed by laminating multiple punching sheets. Generally, the rivets are penetrated into the punching sheets, and then the rivets are locked at the rivet holes to realize the compression of the punching sheets. [0003] When the punching area is sufficient, generally a plurality of rivet holes are set on the iron core, and the punching pieces are pressed together with the rivets. When the punching area is small, it is not enough to open the rivet hole with the smallest diameter to ensure the rotor’s own structural strength, then only glue is used to assemble with lamination tooling, and then the glue is dried to finalize the punching. The use...
