Profile:

With the unique application of Prony (winding) braking.
It automatically obtains the full pull-in and pull-out torque curves with high accuracy.

• Pull-in torque:
  The maximum torque at which the motor can start from the holding state without losing steps for a given speed
• Pull-out torque:
  The maximum torque at which the motor can operate without losing steps for a given loading

Advantages:

• Minimal moment of inertia of the tester:
  By using the Prony method, the measurement is not affected by the inertia and the coupling loss of the test system. Especially in the Pull-in test, more to show this advantage.
• Wide Measuring Range:
  Six modes of sensor, to select the proper sensor and pulley,
  The measuring Range is from 0.1 to 400 mNm.
