PURPOSE:To eliminate a switching element of a large rated value for an arma ture coil driver by providing a switching element to energize or deenergize a controller for controlling the armature coil driver. CONSTITUTION:When a start switch 28 is closed, a transistor 27 is turned ON to energize a controller 24. As a result, a rotating position detector 25 and a rotating speed controller 26 operate to control an armature coil driver 20. An armature coil 13 is controlled to be energized or deenergized by the driver 20 to rotate a rotor 1 as prescribed. When the switch 28 is opened, the operation of the motor is stopped. |
