A permanent magnet rotational motor employs the use of a rotating iron band member which absorbs the magnetic flux of both of the opposing magnet flux fields from stator and rotor magnets. This causes mutually opposing, interacting magnetic flux fields of the rotor and stator magnets to enter in close proximity to one another without opposition. This results in the two interacting fields remaining totally one within the other, until the iron band member between the two interacting fields is rotably extracted, compelling the two interacting opposing flux fields to repel each other and causing the rotor assembly to push the power assembly crankshaft in the desired direction. In this manner the aforementioned repelling and attracting effects between the interacting fields experienced in the prior art, which negates rotation in permanent magnet motors, is eliminated. The present invention also provides a device to maintain the necessary coactive relationship between the opposing magnetic fields of rotor and stator magnets throughout a complete rotational cycle of the permanent magnet motor.
