Abstract
An electromagnetic motor includes a stator assembly having a stator body with at least one pole, a primary coil associated with the stator body and electrically interconnected with a power supply such that electric current is the primary coil creates a magnetic field in the pole, a secondary coil associated with the stator body and magnetically coupled with the body and primary coil, and a permanent magnet armature positioned so that there is a working air gap between the armature and the pole. Termination of current flow to the primary coil results in a collapsing magnetic field that induces an electric current in the secondary coil to reverse the magnetic polarity at the stator pole, and thereby reverse magnetic attractive propulsion force in the armature.
