PURPOSE:To provide the functions of operating frequently switching, low and high speed switching actuations of one universal motor by using an inverter for controlling the motor for controlling a process. CONSTITUTION:An inverter 8 oscillates an output signal of the voltage and frequency set in the inverter 8 by a switching pulse signal from a pulse width output regulator 1. The output signal of the inverter 8 is oscillated when the switching pulse signal is continuously ON, and becomes zero when the signal is OFF. The output signal of the inverter 8 is altered in the phase sequence by a drive circuit in the inverter 8 by a switching signal to alter the rotating direction of a motor. The output signal of the inverter 8 is supplied to a motor actuator 3, which is driven to switch by the output signal. |
