Abstract: An electromagnetic motor apparatus is used for converting electrical energy into rotary motion and includes a housing having a crankshaft rotably mounted therein. A plurality of stators form cylinders and are mounted onto the housing. A plurality of armatures form the pistons and are movably mounted to slide in the stators. Each armature has an armature piston rod connected to each armature and to the crankshaft for turning the crankshaft responsive to the movement of the armatures in a timed sequence. A distributor is operatively connected to the crankshaft for distributing electrical energy applied to the distributor from the distributor to the stator windings. The distributor has at least one pair of electrical contacts moving in a liquid bath responsive to the rotation of the crankshaft to direct electrical energy to the stator in timed sequence so that electrical arcing is reduced in the distribution of the electrical energy in an electromagnetic motor.
