Name three factors that determine the torque produced by an induction motor.
The air-gap flux density of a two-pole induction motor is given by B=Bm cos(ωt−θ)where Bm is the peak flux density, θ is the angular displacement around the air gap, and we have assumed clockwise rotation.

14 P.14 - A three-phase induction motor with 4 magnetic poles, 60 Hz, rotates with a speed of n=1750 rpm In order to achieve a quick stop we can use a proper swap of 2 phases which normally corresponds to an inversion of rotation direction. For fast crossing, the technique of inversion of the direction of rotation by changing 2 phases is used. At the precise moment we swap the 2 phases, what are the slip, s, and the rotor current frequency, fR, like?
A three-phase induction motor, operating at rated voltage and frequency, has a startingtorque of 1.35 times and a maximum torque of 2.2 times, both with respect to its rated-loadtorque. Ignoring the effects of the stator resistance and rotational losses and assumingconstant rotor resistance, determine the slip rated load, and the rotor current at starting (as a percentage of the rotor current at rated load). The slip at maximum torque is 0.343 if that helps.
