Electric Dynamometer: Core Selection and Advantage Analysis for Equipment Testing
When testing motors, engines, gearboxes, and other equipment, electric dynamometers have become a key choice due to their significant advantages. Among commonly used dynamometers, electric dynamometers, with their outstanding energy recovery and fast dynamic response, are widely suitable for full-load testing of high-power equipment. Eddy current dynamometers are suitable for medium-power continuous loading scenarios, but they consume relatively high energy. Magnetic powder and hysteresis dynamometers are limited to low-power precision testing. While hydraulic dynamometers can handle very high power, they lack dynamic testing capabilities.
The energy-saving advantages of electric dynamometers are particularly evident in motor testing. By converting mechanical energy into electrical energy and feeding it back into the grid, electric dynamometers can offset the initial investment in a short period of time through energy savings in testing scenarios above 100kW and at high frequencies compared to lossy eddy current dynamometers. In engine testing, their millisecond-level response speed enables precise capture of transient operating conditions. During gearbox testing, they can simulate complex load changes in real time, a feat unmatched by other dynamometer types.
