ABSTRACT:
Underlying the present invention is the recognition that a conventional electric motor, which has its rotor move only in passing relation to the stator magnetic field-producing coils, is the significant source of inefficiency delaying the development of an effective use of electrical energy. That is said conventional electric motor's ineffective use of the motive power available from the electrical source, rather than any nominal extent thereof, is what primarily restricts the efficient use of existing electric motors and contributes to unpredictable electrical consumption, short circuits when in a stalled position, loss of directional power when starting with a load that causes a counter-rotation, inability to readily change speed and horsepower output, excessive costs of repair, inefficiencies caused by back EMF and other current losses which may amount to 20% of applied current, poor magnetic design, and other such problems, all of which are solved or obviated by the within improved electric motor. Thus, the within invention, which is directed to effective use of electric energy is therefore concerned with an improved electric motor which, as a substitute for the conventional operative arrangement of rotor and field coils as noted above, instead has the rotor urged through movement centrally of, rather than merely past, the field coils, thus obtaining maximum prime mover drive for any electrically powered motor.
