| Servo motor dynamometer test system is suitable for testing AC and DC motors, three-phase asynchronous motors and other motors Characteristics |
The dynamometer's primary role is to measure an engine's power output, and it serves as a versatile loading device for gearboxes, reducers, and transmissions to assess their power transfer capabilities. It is predominantly classified into hydrodynamic, eddy current, and electric power dynamometers. Notably, electric power dynamometers employ electric motors to precisely gauge the torque output on the shafts of diverse power machines, combining this with rotational speed metrics to accurately evaluate power equipment performance.
Given that power machinery operates at various speeds, the motor functioning as a power dynamometer must offer seamless speed regulation. The most frequently utilized types include DC dynamometers, AC dynamometers, and eddy current dynamometers, each providing smooth and adaptable speed control for comprehensive power testing.
Dynamometers are categorized by the type of current they utilize: DC dynamometers, AC dynamometers, and eddy current dynamometers, each offering unique testing capabilities tailored to different testing scenarios.
Dynamometers further differentiate based on their loading methods, comprising hysteresis dynamometers, magnetic particle dynamometers, eddy current dynamometers, and electric power dynamometers, each designed for specific testing requirements.
Industry-specific naming conventions exist, such as 'chassis dynamometer' for testing chassis performance of electric bicycles, electric power-assisted vehicles, and motorcycles. Meanwhile, certain motor test systems are referred to as 'motor dynamometer' or 'motor dynamometer test system' to reflect their specialized testing focus.
Dynamometers, with their diverse principles, exhibit distinct performance characteristics and varying scopes of application, catering to a wide range of testing needs within the industry.
The hysteresis dynamometer primarily targets small power, high-speed motor loading tests, like those for small motors, whereas the magnetic particle dynamometer is suited for low-speed, high-torque, and small to medium power loading tests, such as for small motors or gearboxes.
Eddy current dynamometers are ideal for medium to high rotational speed applications, capable of handling larger power ranges. They are particularly suitable for extensive loading tests on motors, gearboxes, and engines, making them indispensable for comprehensive engine testing scenarios.
