ABSTRACT:
An integral bearing type electric motor is disclosed, which comprises a bearing body including a spindle, a sleeve surrounding the spindle, an inner or outer ring fitted in or on the spindle, and balls provided between the spindle and sleeve, between the spindle and outer ring or between the inner ring and sleeve. A hub for the rotor of the motor, a flange for the base of the motor or a stator yoke holder is formed by molding together with the sleeve, spindle or inner ring of the bearing body. The number of components is reduced, the number of assembling steps can be reduced, and reduction of the cost of manufacture can be expected.
