The dynamometer is used to test the output power of engines and motors, featuring high accuracy and fast response, suitable for dynamic testing. It can also serve as a simulated load at the output end of reducers, gearboxes, and transmissions for load tests. The AC dynamometer excels in low-speed loading performance, with a torque loading range from zero to rated torque, from zero RPM to rated RPM.

Key Features of the Communication Power Dynamometer

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

2. The power measuring dynamometer returns electrical power to the grid (or is consumed by the chopper resistor cabinet) when it is in the power generation state, and can drive the test piece in the electric state.

3. No water cooling system required

4. From zero to rated speed, it exhibits a constant torque characteristic; from rated speed to high speed, it shows a constant power characteristic.

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