ABSTRACT:
Disclosed is a motor apparatus in which the rotation speed of the rotor is controlled by pulse width changes of drive currents which provide a rotating magnetic field around the rotor. A non-saturated type amplifier with poor efficiency can be removed from the motor power supply circuit, thus enabling the motor power supply circuit to be formed only by a circuit having a switching operation.
