    For synchronous motor
    Eg = V1 – IZ

    Z = (0.25 + j 2.5)Ω 
    I = 10 ∠ –36.86 A

    Eg = 141.658 ∠–8.7 V (phase)
    Eg = 245.36 V (line)

    The synchronous impedance of a motor is given as a complex number, with the real part representing the resistance and the imaginary part representing the reactance. In this case, the synchronous impedance is given as (0.25 j2.5).

    This means that the resistance of the motor is 0.25 ohms and the reactance is 2.5 ohms.

    The motor is connected in a Y-configuration, which means that the line voltage is 220 V.
