WebConstruction and Working Principle of a Rotor. In a three-phase induction motor, once an AC is applied to the rotor then the windings of stator strengthen to generate a rotary … WebSep 13, 2024 · The torque at a given slip decreases. The phase angle difference may be reduced slightly because the ratio of rotor reactance to rotor resistance is reduced slightly. I don't think you can attribute the change in the torque vs. speed curve to just the change in the relationship between the rotor resistance and the rotor reactance.
