Abstract
An induction and universal (commutator) motor combination which share a common lamination core and are supplied by a single-phase line. The stator and rotor are provided with multiple poles and phase windings. A winding system for at least one rotor phase winding is common to commutator motor as well as induction motor operation. A lap winding is connected to a commutator, said lap winding having a coil span corresponding approximately to a single pole pitch of the commutator motor stator winding and corresponding as well to an uneven integral multiple of the coil span of the multi-pole induction motor stator winding. The invention finds particular application in regard to drives for automatic washing machines.
