Abstract

PURPOSE:To reduce the eccentricity between a rotor and a ball bearing in a squirrel-cage induction motor by providing a bearing holder at the end ring part of the rotor to secure the ball bearing directly to th rotor. CONSTITUTION:A ball bearing 4 is inserted into the ball bearing holder 2b of the inner surface of an end ring 2 provided at the end face of a rotor 1, the end ring is then caulked, and the rotor 1 and the ball bearing 4 are secured by edge part 2a. Thereafter, a housing 5 integral in contact with the outer peripheral surface 3a of a stator core 3 is press-fitted into the inner peripheral surface 4a of the ball bearing 4 to secure the ball bearing 4 to the rotor 1 and the housing 5. In this manner, the eccentricity of the rotor and the ball bearing can be reduced, and a motor having low noise and long lifetime can be obtained.
