A 15hp (output power), 208V, three phase, six pole, y-connected induction motor has the following parameters:

R1 = 0.1 ohm
R'2= 0.1 ohm
Xeq = 0.5 ohm

A.) A fan type load is connected to the motor. The slip of the motor in this case is 2%. If the terminal voltage of the motor is reduced by 20%, calculate the speed of the motor (you may use the small-slip apporximation).

B.) What is the percentage change of the maximum torque for case (A)?
