J.W. Putt PM/EM Motor-U.S. Patent No. 3,992,132 (Nov. 1976) The permanent magnet/-electromagnetic motor of J. W. Putt is based on converting primary motion in a given path to produce secondary motion in a transverse direction to the given path, as illustrated.

This ununual type of PM/EM energy conversion unit which utilizes radial displacement of permanent magnets to drive pistons for a pumping device should be considered as a hybrid type of arrangement, as noted.

The radial pistons are used as a hydraulic pumping means and are connected together to provide an output of pressurized fluid which may be stored under pressure for convenient usage. The fluid may be used to drive a hydraulic motor and then recirculated through a reservoir to the individual pump means for each of the secondary magnets.

The basic invention involves the balancing of the magnetic forces of attraction and repulsion. This is achieved by having a plurality of interconnected primary magnets with polarities which coact with the polarities of the transversely movable secondary magnets so that the force of magnetic attraction in one direction parallel to the given path of relative movement are substantially equal to the forces of magnetic repulsion in the opposite direction parallel to the given path. This arrangement results in a minimization of th energy required to produce relative movement in the given path between the primary and secondary magnets.

Worthington Magnetic Motor


With the 1972 patent of Tracy and Derouin we get a more recent look at the permanent magnet motor. This design holds with the same idea of placing a shunt at strategic points and at strategic moments of motor operation as does the previous Worthington design. However, a different approach is taken in that, instead of having the shunt roll into place alongside and touching the stationary magnet as with the Worthington design, the Tracy and Derouin design has the shunt moving in and out of the magnetic force field without actually touching the magnet AND also into the field directly between the stationary and the moving magnet.

This design, as with the Worthington design, uses electric solenoids to move the shunts in and out of position—and in addition two designs are given: a rotary design similar to any ordinary electric motor, and a reciprocating design similar in fashion to any ordinary internal combustion engine. The reciprocating design would, however, seem to be a waste of energy in overcoming friction of the many, many unnecessary reciprocating parts (upper drawing) such as connecting rods, insert bearings and piston-type sliding magnets. The rotary type would be considerably more efficient if in fact the device will work as claimed by the inventors.

Again, and as with the Worthington design, the idea is to insert a shunt (preferably of iron or iron alloy) between two like poles of a set of magnets, one stationary and one moveable, to cause the moveable magnet to move toward the stationary magnet, and then at a strategic point of operation to remove the shunt causing the magnets to repel each other. To move the shunts into and out of position an electric solenoid attached to each shunt, energized and de-energized at strategic moments of operation, causes the moveable magnets to be moved either toward or be repelled away from the stationary magnets and thus cause continuous operation of the motor.

As with the Worthington design, an outside source of current is required to operate the electric solenoids. However, the Worthington patent does not say specifically that the outside source of current is to be produced by the motor itself—only that a source such as a generator could be used«, The Tracy and Derouin patent does state in specific terms that the source (an alternator) is to be driven by the motor itself, that the battery (shown in the drawings) is used only for starting purposes and then regenerated by the alternator, and that the alternator (driven by the motor itself) is to supply the necessary current for normal operation, thereby causing continued operation of the motor with NO NEED FOR FUEL OF ANY KIND.

As previously stated, two like poles of two permanent magnets can be made to move toward one another by placing an iron shunt between them. This takes place because the magnetic force of attraction will be greater than the magnetic force of repulsion—AND since magnetic force of attraction IS GREATER than magnetic force of repulsion in the same magnet, these designs have not considered the amount of force required to remove the iron-based shunts from position.

Will the required energy to remove the shunts from position be of greater demand than the repulsive forces of each magnet provided for that purpose PLUS continue operation of the device itself?
