Hello everyone im recently new to this forum and i would like help on the following question:
'A three phase cage induction motor running at full load draws a stator current of 60A at a power factor of 0.8 lagging from a 415v, 50hz supply. Under the following conditions the stator loss is 3.6 kw, the rotor loss is 1.3kw and the percentage slip is 4.5%. The shaft power is 29.4kw calculate the following':
- Shaft output torque
- Efficiency
- Mechanical friction/windage loss
Could someone explain and show me how to work out the above, thanks you!
