The present invention includes an electromagnetic motor having an asymmetric field stator. An aluminum rotor 6 includes a gorup 26 of permanent magnets that occupy a 153 DEG segment of the rotor 6 and are counterbalanced mechanically by brass counterweights 28 on the other side of the rotor 6. An aluminum stator housing 42 includes a large segment 48 of permanent magnets 54 separated by an electromagnet segment 50 from a small segment 52 of permanent magnets 54. The large segment 48 subtends an angle of 122 DEG , the small segment 52 an angle of 22 DEG 50' and the electromagnets 43 DEG . The permanent magnets 54 and electromagnets 56 and 58 of the staotr 42 produce a magnetic field that can have its center shifted from a first position or equator C by 32 DEG 25' to a second position or second equator C'. As the rotor 6 spins the shifting of the center of the magnet field created by the stator 42 imparts momentum to the rotor 6 as it tries to align with the stator magnetic field. The momentum carries the rotor 6 around until the field can be shifted back to its original position C. A magnetic switch 66 controls the timing of the change in the current direction in the electromagnets 56 and 58 to shift the magnetic field at angles of 87 DEG 15' and 119 DEG 40' from the nearest in segment 48.
