Solutions for Chapter 5. A V, 60 Hz, hp 0. Ignore its friction, windage, and core losses for the purposes of this problem. What is the torque angle? How near is this value to the maximum possible induced torque of the motor for this field current setting? What is the motor's new power factor? Substitute 60 Hz for and 8 for P. Hence the speed of the synchronous motor is.

The maximum possible induced torque for the motor at this field setting is the maximum possible power divided by. Substitute V for , for , V for and for. Hence, the operating torque is about of maximum possible induced torque of the motor. Write the new value of. Substitute V for. Write the expression for power angle. Substitute V for , Hence, the new magnitude of armature current is. Calculate the power factor from.

Hence, the new power factor of synchronous motor is. Textbook Solutions.
