Rotor Input vs Copper Loss vs mechanical power;
The rotor input power P2, rotor copper loss Pc, gross mechanical power developed Pm and slip has below-mentioned relation.
P2 : Pc : Pm = 1 : s : (1-s)
P2 – Pc = Pm
(1-s) P2 = Pm
Pc = s P2
Using the formula,
- The total mechanical power is developed in the rotor is equal to the (1-s) times of the rotor input.
- The total copper loss is equal to the slip s times of the rotor input.
- Total mechanical power is equal to the difference between rotor input to rotor copper loss.
The above relation is used to find out the solution for power flow diagrams.
