Torque = Load-Sensor Rating(N) × Pulley Radius(mm)
*1: Torque will be related to motor shaft Radius.

Profile：

Adopting the unique Prony (winding) braking technology,
It is available to measure high-precision T-N curve

Advantages：

• No inertia & No coupling loss：
  Due to using the Prony method, there are no inertial forces and coupling losses during the test. They are crucial that affecting the accuracy of the testing of micro motors.
• Wide Measuring Range：
  Six modes of the sensor, to select the proper sensor and pulley
  The measuring Range is from 0.1 to 400 mNm.
• Monitoring and analysis easier：
  Real-time display of the testing results on the screen.
  Data-File can be exported to Excel format.
• High Speed：
  The Max. Speed up to 60,000rpm
• Add a power analyzer and you can measure V/A/W and the efficiency of the motor.
