Find the duty ratio and neglecting friction and windage, Electrical Engineering

Assignment Help:

A 440-V, 60-Hz, six-pole, wye-connected, wound-rotor induction motor with a full-load speed of 1170 r/min has the following per-phase parameters referred to the stator:R1 = R'2 = 0.5, Xl1 = Xl2 = 2 , Xm = 40 , and a stator-to-rotor turns ratio of 2.5.

The scheme of Figure is employed for speed control with Rd = 0.02 and R = 1. For a speed of 1000 r/min at 1.5 times the rated torque, find the duty ratio δ, neglecting friction and windage, and using the equivalent circuit with jXm moved adjacent to the stator terminals.
