g torque = T^v x \72 Note that the maximum torque is independent of rotor resistance r„ andthus the speed at maximum torque depends on the rotor resistance. Currentat maximum torque is also independent of rotor resistance. The maximum torque occurs at a lower speed than the maximum output.A… … o SYNCHRONISM Fig. 72. Torque curves for Polyphase Induction Motor. Curves 1, 2, and 3 show the effect of successive increases of rotor resist-ance, rotor run on part of curve a—b ; for here a decrease of speed due toload increases the torque. Speed of Induction Motor,—The speed or rotating…
