A test on a 1/4 hp, 120 V, 60 Hz, 1725 rpm single-phase motor reveals the following results:
R1 = 2 ohm
R2 = 4 ohm
X1 = 3 ohm
X2 = 3 ohm
Rm = 600 ohm
Xm = 60 ohm
draw the equivalent circuit diagram and determine the power output, efficiency, and power factor of the motor when it turns at 1725 rpm.
this is how I draw the equivalent circuit of the motor;
the values of forward and backward impedance both become halves of the stated known ohms,
the values of the inductor's Henry have been calculated as the equation of the impedance X = 2πf.L , and so L = X/2πf.
the graphs just looks like this and I had no idea what does it means
