Abstract

A stator of a motor includes a stator core formed of a plurality of teeth and an annular yoke connecting the teeth to each other, and windings wound on the teeth. A rotor of the motor confronts the stator while supported rotatably, and includes a rotor magnet, a rotor core, and a position sensing magnet. The motor further includes a position sensor for sensing a rotational position of the rotor and a circuit board for supplying an electric current to the windings in response to the rotational position of the rotor. The rotor magnet, the rotor core, and the position sensing magnet are integrated into one unit, which is mounted on a shaft of the rotor.
