Abstract
PURPOSE: To simplify the working of short-circuit ring and to obtain a rotor of high reliability by making up the short-circuit ring by piling plural thin plate rings wherein grooves to insert the rotor bar end are formed by punching.
CONSTITUTION: The groove 7a in which the rotor bar end 2 is insered is punched in the thin plate ring 7, plural rings 7 are piled up to form the short-circuit ring 1 so that the cross-sectional area is a required value. The end of rotor bar attached to the rotor core 3 is inserted into the groove 7a of the short-circuit ring 1, and the fit part is secured by silver soldering to obtain a cage rotor. In this way, the manufacturing process of the short-circuit ring 1 is economized, the flexibility of the short- circuit ring itself is increased, the stress applied to the rotor bar due to a thermal deformation of the rotor bar 2 at starting is reduced, and a break of the rotor bar can be prevented.
