Electric dynamometers are used for testing the output power of engines and motors, featuring high precision and fast response, suitable for dynamic testing. They can also serve as simulated loads at the output end of reducers, gearboxes, and transmission systems for loading tests. The AC electric dynamometers excel in low-speed loading performance, with a torque loading range from zero to rated torque, covering zero speed to rated speed.

Primary Features of the Communication Power Dynamometer

1. Direct torque control technology for AC dynamometers to implement torque control.

2. The交流power dynamometer sends electrical energy back to the power grid (or consumes it via a chopper resistor cabinet) when it is in the power generation state, and in the electric mode, it can drive the test piece to operate.

3. No water cooling system required

4. Torque constant from zero to rated speed, power constant from rated to high speed

For the 110kW AC dynamometer, it can provide (load) testing of 700Nm (or less than 700Nm) at any speed between 0-1500 r/min, and can test (load) power of 110kW (or less than 110kW) at any speed between 1500-3000 r/min.
