http://web.mit.edu/kirtley/www/doe_kirtley_may_2011.pdf WebFor example, for 1800 rpm synchronous speed, an induction motor might have a full-load speed of 1748 rpm. On standard induction motors, the full-load speed is typically 96% to 99% of the no-load speed. This is known as slip. Multi-speed shaded pole and PSC motors show maximum speed first, followed by total number of speeds (i.e., 3000/3-Spd).
