Title:
MOTOR COMPONENT PREPARED BY ELECTROLYTIC COPPER AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/087896
Kind Code:
A1
Abstract:
The present invention relates to the technical field of motor assemblies, and relates to a motor component prepared by electrolytic copper and a motor. The motor component comprises: a core, conducting bars, and end rings. The conducting bars are disposed in grooves of the outer circumference of the core, the end rings are disposed at both ends of the core to enable the conducting bars to be short-circuited, and the conducting bars and the end rings form an integral squirrel cage; the conducting bars and the end rings are prepared by an electrolytic copper method. Conventional manufacturing processes of melting and pouring refined copper are omitted, so that the energy efficiency of a motor manufacturing process is greatly reduced, and energy saving of the manufacturing process is implemented; a welding process as in a re-welding manufacturing process of a motor component into which copper bars are inserted is not present, such that a welding point caused by welding with copper is avoided, and the reliability of the motor component is improved.
