The dynamometer serves as an essential instrument for assessing engine power. It can also act as a loading device for gearboxes, reducers, and transmissions to evaluate their power transfer capabilities. Primarily, dynamometers are classified into three types: hydrodynamic, eddy current, and electric power dynamometers. Electric power dynamometers stand out by utilizing electric motors to gauge torque output on the shafts of various power machines. By combining this torque with rotational speeds, they provide precise power measurements of equipment.
Given the variation in speed among different power machinery, the motor serving as a power dynamometer must offer smooth speed regulation. DC, AC, and eddy current dynamometers are frequently employed to meet this requirement.
Based on the currents employed, dynamometers are categorized into three types: DC dynamometers, AC dynamometers, and eddy current dynamometers.
When classifying by loading methods, dynamometers are divided into hysteresis dynamometers, magnetic particle dynamometers, eddy current dynamometers, and electric power dynamometers.
In industry-specific terms, devices such as electric bicycles, electric power-assisted vehicles, and motorcycles undergo chassis performance testing using a chassis dynamometer. Part of the motor test systems may also be referred to as motor dynamometers or motor dynamometer test systems.
Dynamometers differ in principles, leading to varied specific performances and application scopes.
A hysteresis dynamometer is primarily used for small power, high-speed motor loading tests, like those on compact motors. Conversely, the magnetic particle dynamometer is tailored for low speed and high torque applications, suitable for small to medium power loading tests, such as those for small motors or gearboxes.
Eddy current dynamometers excel in medium to high rotational speed applications, accommodating larger loading tests. They are well-suited for motors, gearboxes, engines, and particularly for conducting engine tests.
