A SCIM has the following specifications: 480 V, 50Hz, synchronous speed of 750 rpm, 3-phase, Y-connected, 8-pole, stator resistance of 0.9Ω, stator reactance of 4.9Ω, rotor resistance of 1.53Ω (referred to the stator), blocked rotor reactance of 4.9Ω (referred to the stator), core resistance of 441.1Ω, and magnetization reactance of 50Ω. If it is operating at 735rpm, draw the equivalent circuit of the motor and calculate: 1. The power delivered to the rotor from the stator 2. The rotor losses 3. The total mechanical power delivered to the load 4. The torque delivered to the load 5. The apparent power supplied from the source to the motor 6. The power factor.

Question

A SCIM has the following specifications:
480 V, 50Hz, synchronous speed of 750 rpm, 3-phase, Y-connected, 8-pole, stator resistance of
0.9Ω, stator reactance of 4.9Ω, rotor resistance of 1.53Ω (referred to the stator), blocked rotor
reactance of 4.9Ω (referred to the stator), core resistance of 441.1Ω, and magnetization reactance
of 50Ω. If it is operating at 735rpm, draw the equivalent circuit of the motor and calculate:
1. The power delivered to the rotor from the stator
2. The rotor losses
3. The total mechanical power delivered to the load
4. The torque delivered to the load
5. The apparent power supplied from the source to the motor
6. The power factor.
