ABSTRACT:
Electric motors which utilize a combination of electromagnets and permanent magnets to effect relative rotation of motor components and have the following characteristics: (1) all of the magnets incorporated in one of the relatively rotatable motor components are permanent magnets, which are provided with power boost windings and are thus optionally convertible to electromagnets, and all of the magnets incorporated in the other of those components are electromagnets; (2) all of the convertible permanent magnets are oriented so that the same pole of each magnet (north or south) faces the air gap between that motor component which includes the convertible permanent magnets and the motor component in which the electromagnets of the motor are incorporated, whether functioning as a permanent magnet or as an electromagnet; (3) the relationship between the number of electromagnets (EM) and convertible permanent magnets (PM) is defined by the equation EM=PM+/-1, but where EM > or equal 3 and PM> or equal 3; (4) the electromagnets are wired in such a way that the poles facing the air gap can be either north or south and are varied in accordance with the predetermined sequences in the operator controlled programs; (5) the energization of the wirings in the electromagnets and in the convertible permanent magnets is controlled by switching electronics and an angle of rotation encoder to achieve predetermined rotational movement; and (6) the number of energized convertible permanent magnets and the number (and polarity) of energized electromagnets is varied to increase or decrease the amount of power output.
