A 415 V, 5 kW, 50 Hz, 4-pole, 3-phase wound-rotor induction motor has the following characteristics:
The magnetising current, core losses and rotating losses can be neglected for this question.
The motor is started direct on-line from a 415 V 50 Hz three phase supply.
(a) Calculate the starting current.
(b) Calculate the starting torque.
(c) Discuss how the starting current could be limited for this wound-rotor motor.
(d) If the motor is running at a speed of 1450 rpm, calculate the mechanical output power.
What are the Special Considerations in Planning The dimensions of the foundation should be such that for low-speed machines (operating speed less than 500 rpm) the natural fre
