Putt Energy Conversion System

The 1976 patent of J.W. Putt shown here is not, as such, one of the many permanent magnet motors that have been designed and patented in this century. But it is presented here because it does in fact use permanent magnets, and according to the patent specifications, can be used as the power source for an automobile.

The device is a form of hydraulic pump. Figure two shows a set of magnets, ten in all, attached to piston-type hydraulic pumps and placed around a circular housing. Within the housing is a rotor of permanent magnets, and when this rotor is driven the magnetic force of attraction and repulsion against the surrounding magnets causes them to pump hydraulic fluid—in this particular case, according to the patent specification, at 1000 psi and 2400 cubic inches per minute. Yet the rotor must be driven by an outside source of power.

Figure one shows the device in configuration for the drive train of an automobile. Putt says in the patent specs that the device will produce enough hydraulic power to drive an automobile with the use of an ordinary hydraulic motor designed for such use (hydraulic drive motors are available on the open market).

Putt also says that the magnetic rotor is to be driven by the same means, a hydraulic motor. Putt specifies, more than once, in his patent specs that the device is designed with automotive drive as a use for the device. And since an automobile does not ordinarily carry on board any kind of source for hydraulic pressure and volume in enough capacity to drive the vehicle, it must be assumed that the closed hydraulic system pressure and volume must not only drive the vehicle but also drive the magnetic rotor.

The patent specs do not divulge the source of hydraulic power that drives the hydraulic motor driving the magnetic rotor. But since it would be ridiculous to design an automotive drive train that required an engine, such as a gasoline or diesel engine, to drive a hydraulic pump to drive a hydraulic motor that drives a magnetic rotor of the magnetic hydraulic pump to drive another hydraulic motor to ultimately drive the vehicle—again it must be assumed that the permanent magnet hydraulic puxiip must provide enough volume and pressure to drive both itself and the vehicle. Otherwise why spend the money on so many, many costly components and still end up using petroleum fuels?

The Putt patent also specifies that other means of power can also be derived from the device instead of hydraulic power—such as electrical generation through the use of linear generators at each of the surrounding field magnets, or by mechanical means from the up and down or back and forth motion of the field magnets as the rotor causes them to move upon its rotation.

However, the hydraulic type of power is gone into in detailed specs in the patent text, and is shown somewhat in these drawings. Putt's text says that the power required to drive the magnetic rotor is very small in comparison to the power output of the device because each of the rotor magnets moves into opposite magnetic fields at the same time with one moving into a magnetic attraction force at the same time as the other moves into a magnetic repulsion force, thus almost equalizing the force required to drive the rotor with the only power being required as the difference between attraction and repulsion.
