Under no-load conditions, a certain motor operates at 1200
Chapter 16, Problem P16.34(choose chapter or problem)
Under no-load conditions, a certain motor operates at 1200 rpm with an armature current of 0.5A and a terminal voltage of 480 V. The armature resistance is 2 . Determine the speed and speed regulation if a load demanding a torque of 50 Nm is connected to the motor. Assume that the losses consist solely of heating of RA and frictional loss torque that is independent of speed.
