Worthington Magnetic Motor

Our first look into the Permanent Magnet Motor is this one shown here from the year 1929 invented and patented by H.L. Worthington.

Worthington's idea was to use a rotor consisting of permanent magnets, and a surrounding field also consisting of permanent magnets. The rotor magnets and the field magnets were to have like poles that would face each other at all times causing a repulsive magnetic force to push each magnet away from each other. By placing magnets into a position such as that shown in the drawing, with eight field magnets and four rotor magnets, the push from each magnet equals the push of all others and therefore the device would not rotate.

However, Worthington installed a set of two electric solenoids and a rocker arm at each set of two field magnets. Each rocker arm was to have a heavy iron roller attached to each end and was to be positioned so as to move the rollers into and out of the magnetic field of one magnet at strategic moments of rotation to cause the rotor magnets to be drawn toward the field magnets until they would pass a particular point wherein the roller would change positions,causing the rotor to rotate because of magnetic repulsion.

Each roller was to act as a shunt causing two north poles or two south poles to attract each other until the magnets were in position to continue rotation because of repulsion when the shunt was removed from the position that caused the attraction. Worthington's idea was to use electric solenoids to cause the rocker arm to insert and remove the shunt rollers from the magnetic field at strategic moments of the rotation, thus causing continued rotation.

The drawing shows what looks like bar magnets, but in reality his design used horseshoe magnets, and the drawing would not show south poles as they would also all be facing each other and would be hidden directly behind the north poles as seen in the particular view of the drawing. However, if the device were to actually work, either type of permanent magnet would suffice.

The one thing wrong with Worthington's theory of placing a shunt in the magnetic force field of two like poles to cause them to attract each other, is that placing a shunt between two like poles DOES NOT cause them to attract each other. They will each attract the shunt, but not each other — and if the shunt is of soft iron the two like poles will in fact move toward each other, but only once they are close to the shunt — close enough for the magnetic force of attraction toward the shunt to be stronger than the magnetic force of repulsion of the two like poles of the permanent magnets.

In my own experiments with permanent magnets I have found that you can cause two like poles to move toward each other, but again, only after they are close enough for the attraction to the shunt to be much stronger than the repulsion force. Up until that point the two like poles will repel each other. I have not yet been able to get two like poles to move toward each other to a point where upon removal of the shunt they would repel each other and keep the moving magnet going in the same direction rather than to reverse directions going back the same way it came from to get into the field.
