a. The per phase equivalent circuit of a 460 VL, 8-pole, and 60-Hz, Y-connected induction motor shown in Figure 2 has the following impedances: R1 = 0.77 2 X1 = 1.3 2 XM = 19 2 R2 = 0.8 2 X2 = 0.72 2 I, R, jX, jX2 R/s I, V, Figure 2 At slip = 2.6%, the frietion and windage losses, Prw = 80 W, stray losses Pstray = 20 W, and core losses Pcore = 2.25 kW, calculate: i. The synchronous and motor speeds. ii. The stator current Ii, consider the effects of magnetizing branch Xm, where I # I2. II. The power factor, is it lagging, leading or unity? iy The electromechanical P. and outnut power P.

The Z-parameters that are the impedance parameters of a two-port network are defined by expressing the two-port voltages V1 and V2 in terms of two-port currents I1 and I2. The Z-parameters are calculated by open circuiting one of the two ports at a time …
