ABSTRACT:
A magnetic motor wherein a piston mounted magnet is reciprocated through a predetermined stroke in timed relation to polarity reversal of a pair of electro-magnetic assemblies at opposite axial ends of the piston cylinder. Polarity reversal and the intensity of the magnetic field is varied as a function of piston movement through a distributor to control the output of the motor. Hysteresis and flux leakage is reduced by an arrangement of permanent magnets and magnetic spheroids associated with one of the electro-magnetic assemblies.
