Problems solved by technology

[0002] At present, the DC frequency conversion floor fan motors on the market are magnetized by opening positioning holes on the rotor shell to position the magnetic poles. However, when the magnetic strips are rolled into a ring, the circumferential positioning requires high accuracy, and deviations are prone to occur, which will damage the permanent magnets. The magnetization process has a significant impact on

Abstract

The invention provides a rotor and a motor. The rotor comprises a rotor shell and a permanent magnet sleeved in the rotor shell; the rotor shell is provided with a concave part which is concave towards the center of the rotor shell; the permanent magnet is provided with a groove recessed towards the center of the permanent magnet. Wherein the concave part is matched with the groove, the permanentmagnet is provided with a splicing seam, the splicing seam is located at the groove, and when the concave part is matched with the groove, the deviation angle of the splicing seam is controlled withinthe preset deviation angle range of the splicing seam. The magnetizing process of the permanent magnet can be simplified, the magnetizing structure of the permanent magnet is improved, and the deviation angle of a splicing seam is controlled.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a rotor and a motor. Background technique [0002] At present, the DC frequency conversion floor fan motors on the market are magnetized by opening positioning holes on the rotor shell to position the magnetic poles. However, when the magnetic strips are rolled into a ring, the circumferential positioning requires high accuracy, and deviations are prone to occur, which will damage the permanent magnets. The magnetization process has a significant impact. In view of the above problems, it is necessary to design a rotor and a motor that can simplify the magnetization process of the permanent magnet, improve the magnetization structure of the permanent magnet, and control the deviation angle of the splicing seam. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present application proposes a rotor and a motor, which can simpli...
