Publication number: 20190115809Abstract: In a method for connecting an end ring to conductor strips of a rotor of a motor, a core is provided by stacking silicon steel sheets. Each of the silicon steel sheets comprises an aperture and slots. Conductor strips are made with a cross-sectional shape corresponding to the slots and a length larger than that of the core. The conductor strips is inserted in the slots while locating the ends thereof out of the core. Two end rings are cast by using mold to wrap the ends of the conductor strips while keeping the molds away from the core, filling molten copper in the molds so that the molten copper partially melts the ends of the conductor strips, and cooling the molten copper via the molds so that the molten copper is cooled and hardened to provide the end rings. Then, the end rings is polished.Type: ApplicationFiled: February 6, 2018Publication date: April 18, 2019Inventor: Chao-Chun Peng
