The micro electromagnetic clutch relies on the coil to control the coupling and separation of the clutch. Electromagnetic clutch can be divided into: dry monolithic electromagnetic clutch, dry multi-piece electromagnetic clutch, wet multi-piece electromagnetic clutch, magnetic powder clutch, slip electromagnetic clutch and so on. The working mode of electromagnetic clutch can be divided into: power combination and no power combination.

The micro electromagnetic clutch is a kind of dry monolithic micro electromagnetic clutch with electric working. It is characterized by small volume, quick response, large transfer torque, no no-load loss and long service life.
