Tiny Motor Test System

With the unique application of Prony (winding) braking, which is the most proven

method for torque testing of small / tiny motors. It automatically obtains the T-N characteristic of tiny motor with high accuracy.

For small & Tiny torque testing, this is the most mature and highest precision of measurement method.

Advantages:

• Minimal moment of inertia of the tester
  • By adopting Prony braking, the system provides stable measurement unaffected by moment of inertia of the tester and coupling loss, which is unavoidable in conventional torque testers. For micro motors, zero inertia testing is possible by winding the brake thread directly on the shaft.

Torque / Load-Sensor / Pulleys Specifications are as follows:

• Directly around the axis ^*1: Torque and motor shaft diameters.
• Using a pulley: torque ( mNm ) = Load – Sensor ( N ) x Pulley diameter ( mm ) / 2

Stepper Motor Test System

With the unique application of Prony (winding) braking, which is the most proven

method for torque testing of stepper motors. 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 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 speed

Advantages:

• Minimal moment of inertia of the tester
  • By adopting Prony braking, the system provides stable measurement unaffected by moment of inertia of the tester and coupling loss, which is unavoidable in conventional
  • torque testers. The advantage is obvious especially in pull-in torque testing. For micro motors, zero inertia testing is possible by winding the brake thread directly on the shaft.
