ABSTRACT:
A capstan motor which includes: a stator yoke having a multiple number of coils provided on a circle centered about a rotational shaft; and a rotor yoke having an annular magnet opposing the multiple number of coils and rotating integrally with the rotational shaft, and is constructed such that a hysteresis plate is provided opposing the rotor yoke on the side opposite the multiple number of coils for receiving leakage of the magnetic flux from the magnet and is attached rotatably relative to the rotary shaft; and driving force for rotation is extracted from the hysteresis plate, and a tape driving system using it.
