The induction machine described in Example 6D is operating steadily at no load. The polarity of the applied voltage of one stator winding is suddenly reversed. Assume that the electric system establishes steady state operation before the speed of the rotor has changed appreciably. Calculate the torque. Describe the behavior of the machine.
Example 6D
A four-pole, 110-V (rms), 28-A, 7.5-hp, two-phase,
