Abstract
PURPOSE: To provide an emergency operation apparatus which enables smooth control of the motor at the power failure utilizing a battery with a chopper circuit having an element connected to a switching thyristor composing an armature switching thyristor composing an armature switching static Leonard device.
CONSTITUTION: This emergency operation apparatus includes a thyristor bridge employing a switching thyristors 14a to 14d which is connected to a three-phase AC power source 10 through a converter 11 for converting AC to DC and an armature switching static Leonard device provided with an armature 8 of a cage driving DC motor connected diagonally thereto. In addition, a battery 20 is provided to supply DC power to the thyristor bridge in case of failure of the power source 10. In this case, the DC power is fed to the motor through a chopper circuit comprising diodes 15a and 15b, thyristor 16a and 16b, reactors 18a and 18b, capacitors 19a and 19b and the thyristors 14a and 14b.
