Abstract
PURPOSE: To exactly stop a motor in emergency when the motor disabled itself from controlling by providing a switch mechanism for breaking a current flowing through the motor when the movable contact for controlling the motor is fusion secured to a stationary contact and the motor disabled itself from controlling.
CONSTITUTION: A motor is rotated normally or reversely or stopped by operating a normal and reverse change-over switch 13 and an accelerator switch 14 to energize one of or deenergize both of solenoids 11 and 12. When a contact fusion accident occurs, for example, between the movable contact 10 and the stationary contacts 8, 6 in the state that the right side solenoid 12 is energized, an emergency stop switch 16 is operated to be closed. Then, both the solenoids 11 and 12 are energized through an emergency energizing circuit 15, and the left side movable contact 9 makes contact with the stationary contacts 8, 6. Accordingly, both the terminals of the field coil 3 are connected to the rotor 4 side. Thus, no current is flown through the motor to stop the motor.
