Abstract
PURPOSE:To stop an electric motor by detecting rapid change from normal current by utilizing a characteristic that the power supply current of the motor for opening and closing a switch makes a small change upon the normal operation of a switching body and increases when if any human body is caught in. CONSTITUTION:If an overload applied to an electric motor 4 with any obstacle such as haman body contacting with a switching body, the output B os a filter . amplifying circuit 10 and the passage current C of a variable resistor 13 follows up the change of the power supply current A. The signal D of an integration circuit consisting of a resistor 16 and a capacitor 17 rises slowly. When the signal C is at a higher level than the signal D, the output of a comparing circuit 14 comes up to a high level and due to the output of the circuit 14 and the output signal of a timer 19 the output of an NAND circuit 18 comes to a low level. The output of a comparing circuit 9 is kept at a high level in accordance with the signal not exceeding the setting reference voltage and therefore the output of a NAND circuit 20 comes to a high level. Consequently, a transistor 22 turns on and a relay works to open a contact 12a so that the motor 4 stops revolution.
