Hysteresis Dynamometer

　　Natural convection cooling dynamometer:

　　Hysteresis dynamometer (HD series) is universal and ideal for low and medium power testing. Hysteresis brakes do not need to rely on speed to generate torque, so it can be tested from no load to locked rotor. Brake cooling is provided by convection cooling (no wind source) or air cooling (compressed air AHD series or blower BHD series) depending on the model. Hysteresis dynamometer has continuous and short-term intermittent power to radiate more heat range. According to the size and system composition of the dynamometer, its accuracy is ±0.25% to ±0.5% of full scale. It also provides special designs for high-speed motor testing. Used in the performance testing of various AC and DC motors (torque, speed, power, etc.), it is widely used in the detection of automobile motors, household appliance motors, electric tool motors, compressor motors and aviation motors.
