Abstract
A solenoid motor comprising a crankshaft with a plurality of solenoid means positioned adjacent thereto. Each solenoid means comprises a cylindrical core with an electrical coil wound therearound. A piston means is slidably mounted in each of said cores and is longitudinally movably responsive to the polarity of the coils. Connecting rods are pivotally connected by their opposite ends to the piston means and the crankshaft. An electrical control means is operatively connected to the coils to sequentially control the electrical polarity of the coils wherein longitudinal movement of the piston means is sequentially induced to impart rotational motion to the crankshaft.
