Low Speed Performance High Accuracy 45KW 286Nm AC Dyno For Diesel Engine

Working principle

The AC asynchronous electric dynamometer system usually consists of the DUT(Device Under Test), AC asynchronous electric dynamometer, inverter, energy consumption device (or feedback device) and the measuring and control system for torque/speed test and control.

AC asynchronous electric dynamometer is the load of the DUT in power measuring state, and an AC asynchronous induction motor in power generation state. Under the control of the frequency inverter, it adjusts the electromagnetic torque to change the load and speed of the engine, absorbs the mechanical work output from the tested engine, and converts it into electric energy. The DUT cannot directly measure the output torque due to its structure. In general, the speed and the torque of the motor shaft are measured so as to measure the output torque and power of the engine indirectly. When the dynamometer runs as a motor, it can be used as an ordinary three-phase asynchronous motor to drive the DUT for start, cold running-in and determine the mechanical loss.

The effective power p is calculated by measuring the output torque Mp and speed n of the engine under test under certain operating conditions. The shaft load torque Mp and speed n of the AC asynchronous electric dynamometer are two key measurements of the dynamometer system.
