用電源装置。 A power supply device that drives a large number of hysteresis motors, a control circuit that opens and closes an individual switch provided for each of the motors at a desired cycle at the output of the power supply device, and a control circuit that controls the back electromotive force of the motor when the switch is open. In a power supply device that inputs the voltage rotation speed and the output frequency of the power supply device, calculates the slip from both, and inputs this slip into the control circuit, an overload occurs during operation among multiple hysteresis motors, A power source for driving a hysteresis motor, characterized in that a specific slippery hysteresis motor is provided with a detector for detecting the rotation speed of a back electromotive force, and the output frequency and output voltage of the power supply device are controlled to follow the rotation speed. Device.
