hi everybody
i am trying to prove the mmf equation of two phase balanced induction motor
it is simple but i get cosine and sine equation
mmf=mmf(max)*(3/4*cos(omega*t+epsi)-3/4*sin(omega*t+epsi))
does it mean the mmf is pulsating or rotating one?
if anybody can give a help i will be thankful
also if u can recommend a ref. or link to site to see the calculation of two phase mmf
thnx in advance
