Abstract

PURPOSE:To obtain a controller which stops a main device with a simple structure and a ready maintenance by supplying by frequency conversion or the like a regenerative power of a main motor caused by an inertial rotation to a sub device at the time of power source interruption, thereby enabling to supply electric power to necessary sub device until the main device stops. CONSTITUTION:A switch 113 is closed, a switch 116 is opened at a normal time, electric powers are respectively supplied through main and sub power source systems 106 to main and sub motors 102 and 104, thereby operating a main device 101 and a sub device 103. When a power supply is stopped from a power supply bus 105 due to power interruption or the like, the switch 113 is opened, and the switch 116 is closed. In this case, an induced electromotive force generated by the inertia of the motor 102 is frequency-converted via an inverter 115 of a regenerative circuit 114, is regenerated at the motor 104 of the device 103, and the device 103 is supplied with the power while the motor 104 is rotated, thereby maintaining necessary function.
