PURPOSE:To improve the using perfomance by displaying the speed set of a motor by the input of a speed display signal and providing a display unit for displaying the excess rise of the motor by the input of the excess rise display signal of the motor temperature. CONSTITUTION:Processing means 5a of a microcomputer 5 outputs a control signal to a voltage supply controller 9 through a motor control means 5b on the basis of a speed set signal from an operating key unit 7. A temperature detector 10 detects the temperature of a motor 8, and when a temperature detection signal rises to the temperature to stop the energization of the motor, the excess rise flag of excess rise flag setting means 5c is set to 1, thereby stopping the motor 8. A speed set signal is displayed normally on a display unit 11, and when the excess rise is set to ''1'', the excess rise display signal is displayed. |
