Induction Motor Equivalent Circuit Calculations

Induction Motor Equivalent Circuit Calculations

Induction Motor Equivalent Circuit Calculations

(OP)
I have a motor info as
HP 500 , kVA 450, poles 2, kV 4.16, Slip 1.275 RPM 3554, SF 1.15 , FLA 65
PF FL 100% -> 86%
Eff 100% -> 95
Locked Rotor:
%LRC 690%
%PF 19, T = 35% Tmax = 210

Can you please help me with equivalent circuit calculation and provide me with some references to go from these parameters to equivalent circuit?

RE: Induction Motor Equivalent Circuit Calculations


I can calculate the parameters using my software-hand made on VB6-but I cannot send the
calculation only the results.
I hope it may be useful in a way. It is not possible to be close more than 5% because we have to neglect some of the losses as ferromagnetic losses, friction and ventilation.
For instance rated current will be 63.34A instead of 65A, pf=0.904 instead of 0.86.
