We have a six-pole, 440-V-rms, 60-Hz delta connected synchronous motor operating with a constant developed power of 20 h p, unity power factor, and a torque angle of 10°. Then, the field current is reduced such that Br is reduced in magnitude by 25 percent. Find the new torque angle and power factor. Is the new power factor leading or lagging?
