A 400V, 50 Hz , 80 hp eight pole Δ connected synchronous motor
has a reactance of 0.6 and negligible armature resistance. Its
friction, windage and core losses are 1.2KW, 0.5KW and 1KW
respectively .
- What is the speed of this motor?
- If this motor is initially supplying rated hp at 0.82 PF
lagging . What are the magnitudes and angles of ?
- What is the power factor of the motor?
- How much induced torque and load torque is produced by this
motor ?
- If is increased by 30 percent ,what is the new magnitude of the
armature current?
- What is the motor’s new power factor?
