Dynamometer, as the name implies, is a device to test the power of power machinery, transmission machinery and other machinery. The three parameters of torque, speed and power are the most basic dynamometer. Then the dynamometer consists of analog load and torque sensor.
Root simulated load can be: magnetic powder brake, eddy current brake, motor
The test bench with magnetic particle brake as the simulated load is called magnetic particle dynamometer; The eddy current brake is called the eddy current dynamometer; Electric dynamometer is used to simulate the load of motor.
