Chip cleaner motor overload detection system

The invention relates to a chip cleaner motor overload detection system. The chip cleaner motor overload detection system comprises an induction module, and a control loop, an overload detection loop and a signal butt joint loop which are connected in sequence, the sensing module comprises a three-jaw metal plate arranged on the motor and a proximity switch fixedly arranged on the chip cleaner; the control loop controls the chip cleaner to operate or stop; the overload detection loop is connected with the proximity switch, two time relay normally open contacts are arranged in the overload detection loop, and whether the motor is overloaded or not is judged by judging whether the time relay normally open contacts are closed or not; the signal butt joint loop receives an overload signal of the overload detection loop and then sends out an alarm signal, and the control loop receives the overload signal and then controls the chip cleaner to stop running. Two time relay coils used for time delay are arranged in th
