Abstract

PURPOSE: To enable to perform the start and stop of the rotating magnetic field at the application and interruption of external power supply, by controlling the driving of the rotating magnetic field generating circuit with the output of the monitor circuit.
CONSTITUTION: After alternating current from the external power supply connected to the connection terminal 1 is converted into DC with the AC-DC converter 2, required operating power supply having necessary polarity of plus and minus can be inverted with the DC-AC inverter 3. In this case, the monitor circuit 4, 5 and 6 monitor the output of the converter, input power supply, and operating power supplies 7, 7', outputting the monitor outputs 12...14. Further, the output of the monitor circuits 4...6 control the driving of the rotating magnetic field generating circuit 9, enabling the start and stop of the rotating magnetic field moderately at the application and interruption of external power supply.
