Richard B. Hackenberger, Sr., vice-president in engineering for EvGray, explains how the EMA motor system operates. The spikes are transferred to a small control unit, which in turn operates the major motor unit. The electro-magnets are located on both the rotor and stator of the large motor. Attraction and repulsion between the two sets of magnets causes the motor to operate and generate horsepower. To prevent condensation in the main cylinder, a half-pound of air pressure has to be maintained.
Air is routed through the programmer for functional purposes.
When the ambient temperature is 90 degrees, the motor operates at 170 degrees. In short, the principle of the engine is to create electricity and recycle energy by the fact that every time magnets are energized off the peak of transients, a charge goes back into the battery. The batteries for the EMA motor are furnished by McCulloch Electronic Corporation of Los Angeles. After extensive research and testing, EvGray chose the model 110-75 Energy Center, which is said to produce maximum power for its weight and volume over an exceptionally long life span. Two of the 6-volt batteries are used for operation, while the other two serve as a reservoir.
