Power brake dynamometers are used to test the output power of engines and motors, featuring high precision and rapid response, suitable for dynamic testing. They can also serve as simulated loads at the output ends of reducers, gearboxes, and transmissions for load testing. The AC power brake dynamometers excel in low-speed loading performance, with a torque loading range from zero to rated torque, spanning 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 dynamometer is in power generation mode, sending electrical energy back to the grid (or consumed by the chopper resistor cabinet), and in electric mode, it can drive the test piece to operate.

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 demonstrates a constant power characteristic.

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