A brushless motor for an electric power steering device that assists a steering operation includes: a stator having a plurality of winding sets for a plurality of systems respectively; and a rotator having a ferrite magnet. In the motor, a maximum current flowing without any demagnetization at high temperature is large. Hence, the torque of the motor is easily ensured at high temperature. In particular, when a failure occurs in one system, it is easy to ensure the torque of the normal system even at high temperature.
