As is well known, dynamometers are divided into electric dynamometers, magnetic particle dynamometers, eddy current dynamometers, and hysteresis dynamometers. The selection of dynamometer depends on the different tested components or testing requirements, each with its own unique advantages.
Compared to other dynamometers, electric dynamometers can balance the low-speed and high-speed load dynamometer tests of various power machinery in the loading dynamometer test of power machinery. The most prominent feature is energy-saving. Convert the mechanical energy generated by the prime mover into electrical energy and feed it back to the internal power grid for use by other equipment. This is the main advantage of the electric dynamometer that I want to tell you about.
In addition, the electric dynamometer also has the ability to reverse drag. The electric dynamometer can conveniently convert the motor drag mode, absorb energy from the power grid, and serve as a power mechanical reverse drag prime mover.
