Flexible Dynamometer System Testing for Hybrid and Electric Vehicles

Project Type: Testing motor and inverter designs for hybrid and electric vehicles

Customer: University of Houston’s Department of Electrical and Computer Engineering

Dynamometer: two 7.5 kW AccuDyne AC motoring Dynamometers

Control System: DynoLAB

Other Equipment: regenerative battery simulator system

SAKOR Technologies developed a dynamometer testing system for the University of Houston’s Department of Electrical and Computer Engineering designed to test motors and inverters for use in hybrid and electric vehicle applications. The system features dual opposing 7.5 kilowatt AccuDyne four-quadrant AC motoring dynamometer variable frequency drives, and a variety of subsystems configured for testing electrical machines. The dynamometers are capable of bi-directional loading and motoring, allowing researchers to test different algorithms and designs. One dynamometer will be used for testing permanent magnet motors and the other will be used to test induction motors. The dynamometers operate at up to 8,000 RPMs and offer up to 150% overload capacity, making them compatible with most small hybrid and electrical vehicle architectures.
