Power Dynometers are used for testing the output power of engines and motors, featuring high accuracy and fast response, suitable for dynamic tests. They can also serve as simulated loads at the output ends of reducers, gearboxes, and transmissions for loading tests. The AC power dynometers excel in low-speed loading performance, with a torque loading range from zero to rated torque, covering the speed range from zero RPM to rated RPM.

Key Features of the Communication Power Dynamometer

Direct torque control technology is implemented for AC dynamometers to control torque.

2. The electrical power measuring machine sends electrical power back to the power grid (or consumes it through the chopping resistor cabinet) when in the power generation state, and can drive the test piece to operate in the electric state.

3. No water cooling system required

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

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