Question: In a 2 - pole three - phase ac machine, lg = 1 . 5 mm and Ns = 1 0 0 . During a

In a 2-pole three-phase ac machine, lg=1.5mm and Ns=100. During a balanced, sinusoidal, 60Hz steady-state with the rotor electrically open circuited, the peak of the magnetizing current in each phase is 10A. Assume that at t=0, the phase-a current is at its positive peak. Calculate the flux density distribution space vector as a function of time. What is the speed of its rotation?
