Parallel Path Magnetic Technology for High Efficiency Power Generators and Motor Drives

Parallel Path Magnetic Technology (PPMT) is an advanced magnetic force control technology that is applicable to motors, rotary actuators, linear actuators, and generators. PPMT uses permanent magnets controlled with a field coil in parallel magnetic circuits. PPMT is a simple but revolutionary concept that has been demonstrated in a wide variety of prototype devices. PPMT devices allow the control of a given amount of magnetic flux for less energy input compared to a conventional device. PPMT devices are smaller, lighter, run cooler, and are more energy efficient than their conventional counterparts.
