Abstract
A stator and armature assemblyis provided for a permanent magnet DC motor. The assembly includes an armaturehaving a lamination coreand windings, and a stator structureassociated with the armature. The armature is constructed and arranged to rotate with respect to the stator structure. The stator structure includes at least one permanent magnetproviding a certain flux, and at least one wound core structurehaving a coreand a coilwound about the core so as to define an alternate pole with respect to the permanent magnet. When current to the coil is controlled, flux of the stator structurecan be increased or decreased relative to the certain flux. In this way a motor can operate at different speeds.
