AC electric dynamometer is used to test the output power of engine and motor, with high accuracy and fast response speed, and can be used for dynamic test. It can also be used as the simulated load at the output end of the reducer, gearbox and gearbox to carry out the loading test. The AC electric dynamometer has excellent low-speed loading performance. The torque loading range from zero speed to rated speed is: zero torque to rated torque.

交流电力测功机主要特点
1. Direct torque control technology implements torque control for AC electric dynamometer;
2. When the AC electric dynamometer is in the state of generating electricity, the electric energy is sent back to the power grid (or consumed by the chopper resistance cabinet), which can drive the test piece to run in the electric state
3. No water cooling system is required
4. Constant torque characteristic from zero speed to rated speed, and constant power characteristic from rated speed to maximum speed
For example, a 110kW AC electric dynamometer can provide test (load) 700Nm (or less than 700Nm) at any speed between 0-1500r/min;, Any speed value between 1500-3000r/min can test (load) the power of 110kW (also can be less than 110kW)
