Abstract
A novel magnetic friction clutch is disclosed which is capable of relatively high torque transfer for friction discs of a given diameter, compared to prior art magnetic clutches. A friction coating with good magnetic permeability, such as Ferrous Aluminide or the like, is applied to inner and outer annular regions of the three friction discs and increases the frictional coefficient of the discs with little reduction in the clamping force developed through the clutch.
