What are Dynamometers?

Dynamometer, also called dynamometer, is mainly used to test the power of the engine. It can also be used as a loading device for gearboxes, reducers and gearboxes to test their transmitted power. It is mainly divided into hydraulic dynamometer, eddy current dynamometer and electric dynamometer. Electric dynamometer is a device that uses a motor to measure the torque output on various power mechanical shafts and combines the speed to determine the power. Because the measured power machinery may have different speeds, the motor used as the electric dynamometer must be a motor that can smoothly adjust the speed. The more commonly used are DC dynamometers, AC dynamometers, and eddy current dynamometers.

Dynamometer is also called

According to the current used by the dynamometer, the dynamometers are classified into: DC dynamometer, AC dynamometer, and eddy current dynamometer.

DC Dynamometer

by

1. The electric dynamometer test system uses DJC AC variable frequency feedback feedback loading, and the loading energy is fed back to the grid through the AC load generator;

Energy saving and environmental protection. * Significant energy saving effect, which can convert mechanical energy into electric energy and feed it back to the grid

2. Torque and speed are directly measured by torque sensor;

3. The comprehensive power measuring instrument detects current, voltage, frequency, power factor, etc .; the computer automatically detects, displays and completes data processing, reporting and various curves.

4, for other electrical equipment; * Good two-way loading characteristics;

5. Excellent low-speed loading ability, and can achieve high-speed loading;

6. High-speed torque response speed (ms level);

7. Can be used as a motor to provide anti-pulling capability;

8. Good reliability, long service life, easy and simple maintenance;

9.Simple infrastructure construction, self-air cooling, no external cooling system required;

Comprehensive advantages of Haolong Electromechanical Power Dynamometer:

Whether it is asynchronous / synchronous / DC / frequency conversion / servo / electric vehicle motor / permanent magnet synchronous / brushless DC / switched reluctance motor. . . Low / high voltage motors, etc.

Its load part and torque measurement part (that is, the electric dynamometer part) are universal, but its measuring instruments, sensors, transformers and

Computer processing is different.

As for the configuration requirements of the motor manufacturer or motor repair manufacturer, you can choose from the following configuration table according to its requirements, but the load part and torque measurement part (ie dynamometer part) are also necessary.

It can run in four quadrants, either as a generator or a motor; it can be loaded in both forward and reverse directions.

The loading characteristics are very good: stable constant torque loading can be maintained below the rated speed (even stalled or even reversed) (this is especially suitable for minimum torque and MS curve testing), and stable constant power loading can be maintained above the rated speed.

There are two working modes: [constant torque (load) / constant speed (backward drag)] to meet different test needs. (MS curve is suitable for constant speed loading)

Constant torque and constant speed load control stability is unmatched by other loaders, it can maintain extremely high stability in the whole range of speed (even at zero speed) and torque range.
