Abstract

A rotary motor including the combination of an electromagnetically powered first motor and an electrically powered second motor. The first motor and the second motor being mechanically coupled to each other via a common drive shaft for delivery of produced rotary power. The first motor member includes at least one radially disposed electronically pulsed ON/OFF electromagnet member that magnetically couples to a rotatable permanent magnet member disposed on a flywheel member attached to the common drive shaft. The second motor member being electrically coupled to the first motor member for receiving secondary electrical energy produced from back-emf and/or electric power generated by induction at the electromagnet member. The second motor member is adapted with a flywheel member having embedded permanent magnets that influence the flux fields that surround the rotating armature and stator poles to enhance performance of the second motor. The rotary motor may be mechanically coupled to a vehicle via the common drive shaft to propel the vehicle.
