The micro-controller based Dynamic Parameter Motor Controller utilizes state of the art power management components from leading semiconductor companies, the latest IGBT and Power MOSFET technology and low loss accurate current sensing techniques. These components coupled with proprietary conditioned high power switching techniques result in a low loss controller that monitors and dynamically measures and flawlessly adjusts every motor parameter for optimum performance for motor operation using batteries or generator power sources. 6/28/06 1 KW TYPE C PPMT Motor Prototypes are completed. Two TYPE C PPMT prototype motors were completed and are presently undergoing extensive testing in preparation for independent lab testing. The preliminary testing of the TYPE C motors suggest the same superior performance as the TYPE A motors but with different performance characteristics to address a different market need. The Type C motor is scheduled to be transferred to Flynn Motor Technology Corp during the last quarter 2006 for commercialization. 5/31/2006 74 KVA High Power Density 4 Pole 3 phase 400 HZ PPMT-T2 Generator Design is Completed. A scaled down version of the high power density PPMT-T2 generator is being prototyped for testing at an independent test lab. This generator is designed to replace existing rotorcraft and military/commercial aircraft generators and APUs that currently use a compounded loss, self excited generator. This new design requires no rotor cooling and the use of an innovative high field energy design results in high efficiency at the base rating, not just at the nominal load, and reduces heat losses by several thousands of watts less than the currently used generators at the base rating. The PPMT-T2 generator decreases fuel consumption wasted for producing excessive generator/APU heat losses, thereby increasing the travel range and system reliability. The only way an existing self excited generator can compete with the PPMT-T2 is to operate the self excited generator in an overload condition using increased cooling methods to prevent catastrophic heat failure. This will make the PPMT-T2 the correct generator choice for aerospace system designers, setting a new standard for generator design. The laws of physics will confirm the best design produces the least heat, unless you are designing a heater. Companies that use cooling solutions to improve generator performance are not producing a better generator, but are just applying a bandage, no real performance improvement exists when evaluated against a complete system energy loss calculation, coupled with an increased failure risk.
