Abstract
The electric power steering apparatus includes a brushless motor as an electric motor. The motor has a rotor and a stator 34. The stator 34 includes: a back core BY; a plurality of teeth TS disposed along the circumference of the back core protruding from the back core BY toward its radial center and forming slots SL therebetween; and an exciting coil 38 wound around each of the teeth TS. Each of the slots SL is filled with a resin material. The back core BY is partially press-fitted into a yoke 21 so that the outer surface of the back core BY comes partially into contact with the inner surface of the yoke 21 along their circumferences.
