Motor Loading Performance Testing Under Simulated Challenging Environments
Using variable frequency drive (VFD) direct torque control technology, the AC electric dynamometer achieves precise torque control. When operating in generator mode, the electric dynamometer transfers energy back to the power grid or dissipates it through a resistor box. In motor mode, it drives the test subject. This system boasts exceptional reliability and fast response times. From zero speed to the rated speed, it maintains constant torque characteristics, and from the rated speed to the maximum speed, it operates with constant power characteristics.
