Abstract
A rotating electromagnetic apparatus has a stator frame supporting spaced apart pairs of permanent magnets which are arranged with like magnetic poles mutually facing. A toroidally shaped rotor frame is radially wound with a plurality of wire coils immersed within slots in the in rotor frame, the slots positioned adjacent to the opposing magnets. An electromechanical commutator is used to direct current between an outside source or sink through brushes to rotating multiple contacts simultaneously. The brushes are triangular in cross section. The coils may be connected in series or parallel interconnection.
