WINDING TYPE PERMANENT MAGNET SLIP CLUTCH AND APPLICATION

WIPO Patent Application WO/2016/015517

A1

A winding type permanent magnet slip clutch, comprising a permanent magnet rotor and a winding rotor coaxial with the permanent magnet rotor. An air gap is provided between the permanent magnet rotor and the winding rotor. The permanent magnet rotor is mounted on a first rotating shaft (2). The winding rotor is mounted on a second rotating shaft (8). A collector ring (7) and a carbon brush (6) are disposed on the second rotating shaft (8) and form a circuit together with a coil winding (5), wherein on and off of the circuit can be controlled by an electrical switch (K). An induced current is generated in the coil winding (5) by using the slip between the two rotors. The coil winding (5) with the current can be affected by the electromagnetic force in the magnetic field of a permanent magnet, and then transmission of torque can be achieved. The electrical switch (K) controls the on and off of the circuit so as to control engagement and disengagement of the permanent magnet slip clutch. The clutch has the overspeed protection function, the overload protection function, the soft start function and the speed regulation function and can serve as a brake free of frictional contact.
