Electromagnetic clutch works by using electromagnetic force to form a surface friction or engagement, and the use of electromagnetic induction between the drive shaft and the driven shaft cut off or electromagnetic torque transmission mechanism. Electromagnetic clutch in operation and under load conditions, for various mechanical actuator drive shaft and the driven shaft to achieve rapid connection, separation, or on the brake output torque of the driven shaft, steering adjustment, both can be successively separated the two coaxial drive shafts, in turn be connected to separate drive shafts in which the idler gear member. If the side of the fixed part of the electromagnetic mechanical clutch is connected to the electromagnetic clutch may also be used as the brake. 

    Simple structure of the electromagnetic clutch, so it is also very easy to install and maintain them. However, in the course of the electromagnetic clutch may occur due to various factors different fault, then the electromagnetic clutch common faults are generally what type it? The following is a brief introduction of common faults and causes an electromagnetic clutch. 

    Electromagnetic clutch and more general failure occurred in the start, idle and load time, but in a higher incidence of startup period, mainly as unable to start, or enter through the bottom voltage electromagnetic clutch, the conventional input voltage is DC24V. And dynamic instability, slipping or the temperature is too high. But there are special circumstances, so pay attention when the input voltage requirements, exclusion method is to detect whether the input voltage requirements for electromagnetic clutch voltage. Coil shorted encounter this failure are usually replaced or repaired, it is recommended to replace or modify the electromagnetic clutch circuit transformation. 

    Unstable operation, the input voltage is likely to be unstable, testing the power of power is greater than about 1.5 times the rated power of the electromagnetic clutch, voltage fluctuations within + -5% range. Solve the unstable operation method is to check the voltage, the voltage stability. Then there is friction and heat up a situation, due to the heat cause the coil to burn out or short circuit.
