Automotive window winder turning effort

16 May 2019


  • Rotary torque sensor and AFTI display
  • Brackets to mount drill to measuring equipment


  • Portable bespoke tool to measure customer ergonomic effort
  • Peak torque and continuous running torque data recorded and indicated


The customer requested a portable system which would quickly and easily allow him to test the torque required to open and close windows in a car. The maximum torque required to start the rotation of the window mechanism should be recorded. In addition the 'running torque' required to maintain the rotary movement of the mechanism should be displayed.


A rechargeable battery-powered drill was adapted to fit a rotary torque transducer and an AFTI torque display. The drill was set to operate at a fixed speed equivalent to 30 rpm. A female adaptor was fitted to the square drive of the rotary torque transducer, which held the spline of the window mechanism. The AFTI was set to 'normal' display to monitor the running torque required to operate the mechanism. The alarm band of the AFTI was set to upper and lower limits to visually indicate if the running torque was within the prescribed tolerances. Upon completion of the test, the peak torque to start the rotation was recalled by pressing the 'MAX' key on the AFTI display.

Test equipment

  • 10 N.m Rotary torque sensor
  • AFTI display
  • Battery-powered drill
  • Brackets to mount AFTI display and sensor
  • Female adaptor to suit window mechanism
