Abstract
A disc machine has a stator from which teeth and a central boss project axially in the same direction with the central boss projecting beyond the teeth. An AC winding is wound through the slots between the teeth while a DC winding surrounds the central boss. A bar-like rotor has a central aperture and is mounted for rotation so that the boss passes through the central aperture with an axial gap between the rotor and the teeth.
