PURPOSE:To stop a motor or an internal combustion engine which is a power driving part by interlocking a small-sized generator with an output shaft of an overload detecting and automatic stopping device and actuating a relay switch to on and off with electricity generated by the generator as a power source. CONSTITUTION:In case the motor is made the power source, when the motor is started pushing a starting switch by the hand and it starts to be rotated, the generator interlocked with the output side of an overload protective device is rotated and the electricity generated by the generator is made the power source and the relay switch is made on and the motor continues to be rotated even if the hand is released. On the contrary, when an over-torque state occurs, since a clutch slips and the generator does not generate the electricity, the relay switch does not function and the rotation of the motor is stopped. When the cause of the over-torque is eliminated, the motor can be again rotated without tampering with the device especially and the electricity generated by the generator is made the power source only by interlocking the small- sized generator with the rotating shaft at the output side of a slip device and the motor which is the power driving part can be simply stopped by releasing the relay switch. |
