For 50 (60) Hz motors, I0/In (no-load current/rated current) decreases with motor power from 0.5 to 0.8 (in sub kW power range) to 0.2 to 0.3 in the high power range, but it increases with the number of pole pairs. For low airgap flux densities, the no-load current tends … Read More »https://electrical-riddle.com/wp-content/uploads/2021/08/1748497438_906.gif
