Abstract

The invention provides a manufacturing method of a mouse cage assembly, and relates to the field of electric appliances. The manufacturing method of the squirrel cage assembly comprises the following steps: processing to obtain a conducting bar and a rotor core, wherein the rotor core is provided with two opposite end surfaces in a first direction; enabling the conducting bars to penetrate through the rotor core in the first direction and protrude outwards out of the two end faces; obtaining corresponding end rings close to the end faces through additive manufacturing, wherein the end rings are fixedly connected with the guide bars; and in the first direction, the distance between each end face and the corresponding end ring is less than a preset value. According to the manufacturing method of the squirrel cage assembly, the integrality of the squirrel cage assembly is improved, the inherent frequency of the squirrel cage assembly is optimized, then the squirrel cage assembly is not prone to resonance with external excitation in the operation process, vibration is reduced, and the service life of the squirrel cage assembly is prolonged.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a method for manufacturing a squirrel cage assembly and the squirrel cage assembly. Background technique [0002] The motor rotor is the rotating part of the motor. The rotor of the squirrel-cage motor generally includes a motor shaft and a squirrel cage assembly, and the squirrel cage assembly is sleeved on the outside of the motor shaft. Relevant squirrel cage assemblies are generally spliced ​​by multiple parts. By controlling the dimensional tolerance of each part of the squirrel cage assembly and controlling the assembly dimension chain during the assembly process, each component of the squirrel cage assembly after splicing is controlled. Part spacing. Such a squirrel cage assembly will generate relatively large vibrations when rotating, which shortens the service life of the squirrel cage assembly. Contents of the invention [0003] The invention provides a manufact...
