A six-pole 240-V-rms 60-Hz deltaconnected synchronous
Chapter 17, Problem P17.45(choose chapter or problem)
A six-pole 240-V-rms 60-Hz deltaconnected synchronous motor operates with a developed power of 50 hp, unity power factor, and a torque angle of 15. Find the phase current. Suppose that the load is removed so that the developed power is zero. Find the new values of the current, power factor, and torque angle.
