Sakor Technologies, Inc. recently introduced its Accudyne family of AC Motoring Dynamometers. The Accudyne offers an extremely flexible dynamometer system that is readily compatible with a broad range of testing applications, including conventional engine and powertrain systems, hybrid vehicle drives, electric motors and rotary components, such as alternators, generators, pumps, compressors and much more. Available in sizes ranging from fractional to over 2,000 hp, and speeds in excess of 30,000 rpm, Accudyne dynamometers are appropriate for almost any rotational testing need. Modern vector drive technology allows the Accudyne system to provide true 4-quadrant capability, with completely seamless crossover between motoring and loading modes. It also offers the most precise speed and torque control available, especially in low speed applications where full torque can be applied all the way to stall (zero speed). For more sophisticated testing requirements, the Accudyne dynamometer family offers advanced features, such as inertia simulation, engine simulation and NVH Testing.
