Method for manufacturing rotor of induction motor

The present invention relates to a method for manufacturing a rotor of an induction motor, and more particularly, to a method for manufacturing a rotor in which a rotor bar and an end ring of a rotor are integrally manufactured by using copper powder. According to the present invention, the rotor bar and the end ring of the rotor are integrally manufactured by using copper powder, so that it is possible to reduce a manufacturing time and manufacturing cost, to simplify a manufacturing process, and to expand mass productivity, as well as improve the performance of an induction motor. 본 발명은 유도 전동기의 회전자 제조방법으로서, 보다 구체적으로는 구리 분말을 이용하여 회전자의 로터바와 엔드링을 일체로 제조하는 회전자 제조 방법에 관한 것이다.
