Abstract:
1. A motor for electric power steering, comprising: a motor main body for outputting an assist torque to a steering wheel of a vehicle; a resolver provided to one end portion of a shaft of the motor main body, for detecting a rotational position of a rotor provided to another end portion of the shaft; a controller provided between the resolver and the motor main body so as to be shielded from the resolver, for controlling supply of a current from a battery mounted in the vehicle to the motor main body so as to control driving of the motor main body; and terminals for electrically connecting the resolver and the controller, for transmitting an output voltage from the resolver to the controller, the resolver including a stator core having teeth, an insulator covering the stator core, and coils wound around the teeth through the insulator, wherein the motor includes a sealing means that is provided between a housing separating the controller from the resolver and the insulator that is opposed to the housing, and that surrounds a fixing portion for fixing base end portions of the terminals, for preventing a foreign substance from entering an interior of the controller.
