1) Given a P-Pole induction machine p > 2, drive the speed of MMFs and MMFr for a person standing on the stator and the rotor.

2) When ω_r > ω_e, explain what happens to MMFr that is different than when ω_r < ω_e.

3) The stator winding of the induction machine described in problem 1 are connected to a 200-rad/sec source with

Vas = Vscos(200t)

Vbs = Vscos(200t - 120)

Vcs = Vs cos(200t + 120)

And ω_rm = 115 rad/s.

Indicate the frequency of the stator and rotor and rotor currents in table 1: express all answers in rad/sec.

Table 1-

	Actual (abc) variables	Startionary reference frame ω = 0	Rotor reference frame ω = ωr	Synchronous reference frame ω = ωe
Frequency of stator currents

4) Ias = 10cos(100t) in a balanced 3-phase system. Fill in the table below assuming you use the reference frame transformation presented

	Reference frame with ω = 0	Reference frame with ω = 10	Reference frame with ω = 100
Frequency of currents
