Abstract

A hysteresis clutch, more particularly for cooling fans 5 of motor vehicles, has an energising part 7, 8 carried by a rotor 9, and a hysteresis part 3 connected to the fan 5. The energising part comprises two concentric rings 7, 8 which are rotationally fast with one another and axially nondisplaceable. The soft magnetic rings 7, 8 are polarised by a coil 13 and have impressed poles of the same number which are peripherally offset in relation to one another. The hysteresis part 3 is constructed as a ring of permanent magnetic material and is rotatably guided between the energising rings 7, 8. <IMAGE>
