Induction Motor Equivalent Circuit
Example - consider a three phase motor 400 V motor with 4 pole pairs and the following equivalent circuit parameters R 1 =1 Ω, X 1 =3 Ω, R′ 2 =1 Ω and X′ 2 =2 Ω. Plot the torque slip characteristic. Also consider the effect of varying the referred rotor resistance, R′ 2 (1, 2, 4 and 8Ω).
