theorème d'ampère IH dl = Ienlacé
Or dans le rotor et le stator nu r tend vers l'infini donc 
de plus plan verticale pour le champ magnétique donc les deux produits scalaires sont identiques dans l'entrefer
il ne reste que 2Hair(gamma)e= 2B(gamma)e/nu0 = i1(t)
soit B(gamma): nu0i/2e
Si on ajoute des spires convenablement réparties le champ se rapproche d'une sinusoide
B(gamma) : Ksicos(gamma)er

champ glissant statorique
KsIscos(gamma - wt )er
Champ glissant rotorique
KsIscos(gamma - Teta )
Energie magnetique stockee dans lentrefer :
Um=piael/2nu0 * ( Ks2Is2+Ks2i22 + Kr2Ir2 + 2 KsKri1Iscos(teta - wt))
moment electromagnetique = 6Um/6Teta
