Motor Control and Power Conversion Technologies Using FLEXMOD

There is a market need for an efficient, modular motor controller capable of operating with a range of motor sizes and types. The wide applicability and low cost could result in substantial energy savings in industry, residential and hybrid vehicle markets. Under this project, Raser Technologies developed the FlexMod™ controller using Symetron™ technology. This motor controller design uses adaptive tuning to optimize performance based upon unique motor characteristics. The prototype drive can use various power modules and different IGBT designs. Advanced Energy tested the FlexMod™ controller and a comparable, commercially available controller on a 5 hp and a 20 hp AC induction motor. The tests produced a system efficiency map over 300 to 1800 rpm and 25% to 125% rated torque. The tests demonstrated that the FlexMod™ design was 2 to 10% more energy efficient on average
