ABSTRACT:
A motor includes two reciprocating electromagnets. The magnets are energized at positions when the total repulsive forces of the electromagnets can be applied to a single crankshaft. The electromagnets are energized when the crankshaft is 90.degree. past top dead center, in a position to provide maximum torque. One of the electromagnets is positioned by a groove follower which rides in a cam groove cut in a face of a camshaft. The camshaft is connected by a connecting linkage to the crankshaft to follow it. The cam moves the second electromagnet such that the air gap between the two electromagnets is reduced to zero when the first electromagnet is 90.degree. past top dead center.
