LA VITESSE DE SYNCHRONISME
NS = 60 X F / P (EN TR/MIN)
F :FREQUENCE EN HZ
P : NOMBRE DE PAIRES DE POLES



Les vitesses synchrones possibles en fonction du
nombre de paire de pole
P= f/ns
f:frequence Hz
ns: nbr tours/min ou en seconde
2 = 3000 tr/min ::: 4 = 1500 tr/min

LE GLISSEMENT 
G = (NS –N) / NS
NS : VITESSE DE SYNCHRO
N VITESSE ROTOR

LA PUISSANCE UTILE
PU = 2 X PI X N) / 60
C : COUPLE EN NM
Ω= (2 X PI X N) / 60 vitesse en radiant/s

LA PUISSANCE ABSORBEE EN TRI
PA = U X I X √3 X COS Φ(EN W)
U : TENSION EN V
I : COURANT EN A

LA PUISSANCE ABSORBEE EN MONO
PA = U X I  X COS Φ EN W
U : TENSION EN V
I : COURANT EN A

LE RENDEMENT
N= PU /PA
PU : PUISSANCE UTILE
PA : PUISSANCE ABSORBEE
