Abstract:
A stepping motor in which the rotation of a rotor (22) composed of a permanent magnet can be suppressed in an excellent state even when no drive signal is supplied to exciting coils and which is provided with open loop-like exciting coils (201 and 202) which impress rotating magnetic fields upon the rotor (22) upon receiving excite signals and a closed loop-like braking coil (210) which applies a braking force to the rotor (22) around the rotor (22) in the direction of rotation.
