New system provided for testing of aircraft starter/generators

The 18kW AccuDyne AC Dynamometer is capable of operating at up to 14,000 RPM. This dynamometer, along with the inverter provided by SAKOR, is designed to test a new starter/generator product for aircraft applications, in both starter and generator mode.

The DynoLAB Test Cell Control System can also perform a wide variety of load profiles and simulations, and is designed to make it easy for engineers and technicians to create their own test sequences in minimal time.

“This test system provides high precision, three-phase monitoring of electrical power in and out of the starter/generator, as well as accurately measuring torque, speed, and mechanical power in or out of the unit. We can effectively test all aspects of this product in both operating modes with a single test system,” said Randal Beattie, President of SAKOR.

“The AccuDyne’s regenerative design allows it to simulate the engine, as a load, during the start phase, as well as the main driver during the generation phase of operation. It also allows for recapture of absorbed power. This significantly improves system efficiency, and reduces power consumption and overall testing costs.”

By creating an effective, efficient SGU, as tested by this new system, the customer will be able to provide significant benefits of reduced weight and therefore fuel costs in aviation applications.

The SGU offers the same performance as separate starters and generators in aircraft, though combined into a single, lighter weight, package.
