The synchronous motor is rated at 208 V, 45 hp, 60 Hz, delta-connected synchronous motor and power factor of 0.8 leading. The reactance is 2.5 2 and negligible resistance. Its friction windage losses are 1.5kW, and its core losses are 1.0 kW. Initially, the shaft is supplying 15 hp load at the motor's power factor is 0.80 leading. The field current is 4 A. a) Sketch the phasor diagram of this motor, find the value of armature current and internal generated voltage. b) Assume that the load now is increased to 30 hp at rated field current. Calculate the values as (a) and draw the phasor diagram in response to this change. What is the new motor power factor?
