The Hysteresis dynamometer is a device that is frequently utilized for low and medium power testing. This device is known for its versatility and is considered ideal for such testing because of its unique properties. The Hysteresis brake is a critical component of this device and is designed to generate torque without having to rely on speed.
The unique characteristic of the Hysteresis brake lies in its ability to generate torque without require a minimum amount of speed. This special quality allows the Hysteresis dynamometer to perform testing on loads that range from no load to locked rotor. Unlike its alternatives, the Hysteresis brake does not require the presence of minimum speed before it can generate the required torque. This makes it an excellent choice for low and medium-power testing.
There are several benefits of using a Hysteresis dynamometer, whether it is for low or medium-power testing. Its unique design that allows it to generate torque without requiring minimum speed makes it an efficient and effective testing device. It is also known for its durability, reliability, and longevity. Additionally, this type of dynamometer does not require extensive maintenance to keep it in good condition, thus reducing long-term costs significantly.
The Hysteresis Dynamometer, specifically the AHD series, is a versatile and optimal choice for low and medium power testing. Unlike other braking systems, the Hysteresis brake is capable of generating torque without the need for relying on speed. This means that it can effectively be tested under a range of conditions from a no load state to a locked rotor.
There are two types of brake cooling available for the Hysteresis dynamometer, namely convection cooling (without wind) or air cooling (with compressed air AHD series or blower BHD series) depending on the model. Additionally, the dynamometer can produce continuous and short-term intermittent power to accommodate drastically different power levels and radiate more heat in the process.
The accuracy of the Hysteresis dynamometer depends on the size and system composition of the dynamometer, but it typically has an accuracy range of ±0.25% to ±0.5% of full scale. The system boasts special design purposes catered towards high-speed motor testing.
The Hysteresis dynamometer is widely applied in performance testing across motors, especially AC and DC motors. It effectively measures torque, speed, power, and more. It is favored in the detection of automobile motors, household appliance motors, electric tool motors, compressor motors, and aviation motors.
