A rotor for a squirrel cage rotor - motor and a squirrel-cage rotor - motor

摘要

A rotor for a squirrel cage rotor - motor has a plurality of feeding rail (4), which, in regular intervals along the circumferential direction of a rotor core (1) are arranged; short-circuit rings (5) which, with the ends of the feeding rail (4) are connected; and reinforcing - covers (6), the axially direction - have areas which, in contact with an axially directional - end faces of the short-circuit rings (5) are. The reinforcing - covers (6) are formed by casting in the short-circuit rings (5) are enclosed. Retaining rings (7), on the outer circumferential surfaces of the flange areas (6b) of the reinforcement - covers (6) and the outer circumferential surface of the short-circuit rings (5) mounted by means of a press fit.
