Abstract

The magnet core of an electromagnetic clutch is substantially J-shaped in radial cross-section and includes an outer pole ring which is spaced radially outwardly from and which only partially surrounds the outer pole ring of the rotor of the clutch. The controlled transfer of flux between the core and the rotor occurs both in a radial direction and in an axial direction.
