Abstract :
This paper describes a micro torque measurement device based on the cable brake principle. The miniature cable brake permits the measurement of torque produced by miniature motors in the μNm range with a resolution of 0.1 μNm and rotational speeds up to 50,000 rpm. The relative error is about 7.5 %. Work on further system miniaturization for application on micromotors is in progress.
