Compressed Air Cooled Hysteresis Dynamometer / Hysteresis Brake Dynamometer High Accuracy
Name:Compressed air cooled hysteresis dynamometer
Model: AHD-203
Product introduction:
for low to medium power tests. Hysteresis brakes do not rely on speed to generate torque, so full-scale testing from no load to locked rotor can be performed. Brake cooling is provided by convection cooling (no air supply) or air cooling (compressed air AHD series or blower BHD series). Hysteresis dynamometers have intermittent and short-term emission of more heat. range. Depending on the size of the dynamometer and the system composition, the accuracy is ±0.25% to ±0.5% of full scale. A special design for high speed motor testing is also available. Used for performance testing (torque, speed, power, etc.) of various AC and DC motors, it is widely used in the detection of automotive motors, household appliances motors, power tool motors, compressor motors and aerospace motors.
Features
1.10 standard specifications, the maximum torque from 1kg/cm to 140kg/cm
2. Hysteresis Brake System: Provides accurate torque load independent of speed
3. Motor test from no load to locked rotor
4. Accuracy: ±0.25% to ± 0.5% (full scale) High precision load and speed sensor
5. Airflow detection: prevent overheating and operator error
6. Base: optional long plate type / short plate type
7. Custom dynamometer: for special torque, special speed demand
8. Use weight correction for easy correction
