PURPOSE:To stably control a motor for a variation in a load by continuously sending a current at the initial of rotation for the prescribed time, and intermittently sending a current thereafter. CONSTITUTION:A microcomputer 107 continuously sends a current to a motor 102 until the counted value of a motor initial rotation power source synchronization signal becomes the prescribed number N0. When the counted value becomes the prescribed number N0, an initial FLG is set to '1', the counted value is reset to '0' at every prescribed value N1, the motor 102 is deenergized until becoming the value N1 when the counted value is N2 or lower, and the motor 102 is energized when N2 or higher. In other words, a current is continuously sent at the initial rotation for the prescribed time, and the motor 102 is thereafter energized intermittently synchronously with the synchronizing signal of power source. |
