Reducing costs over off-the-shelf solutions, SAKOR Technologies’ dynamometer testing system is in the hands of a major original equipment manufacturer (OEM) for testing starter/alternators for hybrid/electric vehicle (H/EV) applications. The dynamometer test system consists of a 42 kW AccuDyne AC motoring dynamometer and features SAKOR’s DynoLAB test automation controller. AccuDyne dynamometers offer full four-quadrant operation with seamless transition between loading and motoring modes. The system communicates with the user’s ECU via CAN bus technology.
Â
This testing system is capable of operating at speeds as high as 18,000 rpm and as low as 0 RPM, providing full torque in a stall condition. Furthermore, the dynamometer can run in motoring or loading modes at maximum rated torque/power in either direction at any time and can switch between these modes instantaneously. As a result, the test system can expose starter/alternators to all possible conditions they may undergo in actual vehicle use.
Â
This test system offers the ability to test the maximum power, speed, and generator capacity of starter/alternators. In addition, the system allows operators to run road load cycles to simulate real world conditions, including starting the engine, dynamic braking, power assist, and battery charging modes.
Â
Other features include two battery simulators that are also regenerative dc-power supplies. One simulator can supply power at up to 120V and 400 amps; the other unit can supply up to 40V and 1200A. As a result, the system can test the full range of components, while keeping costs relatively low. For more details, visit SAKOR Technologies, call 989-720-2700, and/or email [email protected].
