Abstract
An electric rotary machine provided with a toroidal winding has a stator core made of annular punched seamless laminations. Insulation members, each having partition plates, are mounted on the stator core. Crossover conductor portions interconnecting unit coils of the toroidal winding are retained and guided by the partition plates. The unit coils in each of the slots formed in the stator core are wound by a single continuous electrical conductor, to yield a machine of highly improved performance.
