Abstract:
Torque measurements that account for the influences of temperature and rotation are vital in determining the efficiency of rotating electrical machines on test benches. During experimental efficiency measurements, the influences of temperature and rotational speed generate errors in the torque measurements that could also affect the overall traceable efficiency measurement on test benches. In this paper, experimental efficiency mapping results with a focus on the influence of rotation and temperature on torque measurements are presented.
