ABSTRACT:
An electric motor which includes in the stator or the armature or both one or more assemblies of an electromagnet and permanent magnet contained in the same a magnetic flux circuit. The electromagnet is periodically energized from a battery or other appropriate electric current source by switch means comprising a commutator or the like on the armature whereby the enclosed magnetic flux circuit is nullified or otherwise disrupted and the permanent magnet is caused to react and create relative movement with further magnetic means in the stator or armature, the armature being thereby rotated. The windings for the electromagnets may be located near the center of the armature, or in the stator, the windings may be substantially spaced from the armature if desired.
