A 2-pole, 3-phase induction motor has the following physical dimensions: radius r=7cm, length l=9cm, and the air gap length lg=0.5mm. Calculate the magnetizing inductance Lm for this machine, if it was designed such that the peak of the flux-density distribution does not exceed 0.8T when the rated voltages of 208V (line-line, rms) are applied at the 60Hz frequency. Answers must be in mH, correct up-to two decimal places. Make sure your answers make physical sense.
