Abstract: PURPOSE:To largely decrease a vibration and a noise by forming a core for forming a rotor of a pulse motor in a solid state, and driving the motor by a commutation drive circuit. CONSTITUTION:A rotor 5 is composed of solid cores 61, 62. When transistors (Tr) 72A, 72B are ON, currents are flowed from a DC power source 71 to windings 3A, 3B. When the Tr72A then becomes OFF and the Tr72A bar becomes ON, a current flowed to the winding 3A is interrupted, but since the windings 3A, 3B bars are inductively coupled, a DC power source 71 is commutated through a diode 74A in a direction of an arrow X as shown to the winding 3A bar. After the current of this direction becomes zero, the winding 3A bar is excited by flowing a current through the Tr72A. This operation is performed whenever the phases are switched, and a motor is rotated.
