Would a positive-rotating harmonic or a negative-rotating harmonic be more harmful to an induction motor? Explain your answer.
An AC induction machine has six poles and isdesigned for 60-Hz, 240-V (rms) operation. When themachine operates with 10 percent slip, it produces60 N-m of torque.a. The machine is now used in conjunction with an800-W constant power load. Determine the speedand slip of the machine when used with theabove-mentioned load.b. If the machine has an efficiency of 89 percent,what minimum rms current is required foroperation with the load of part a?Hint: You may assume that the speed–torque curve isapproximately linear in the region of interest.

When drawing the steady state electrical model (for an AC induction motor), is the stator armaturre inductance considered? Why/Why not?
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.
