Find the expression for the no-load speeds, Electrical Engineering

Assignment Help:

Q For a three-phase, fully controlled, recti?er-fed, separately excited dc motor, corresponding to ideal no-load operation, find the expression for the no-load speeds. Comment on whether no-load speeds could be negative. Compared to the one- phase case, would you expect a considerable reduction in the zone of discontinuous conduction?
