Answer Posted / ych
Xc = V(1+n*n)/Io
Where V represents the line voltage; n the turns ratio; Io
the sub-circuit current. The capacitance is obtained
by:
C=Xc/2*π*f
When the auxiliary-winding current is equal to the amount
of current absorbed by the main winding divided
by the turns ratio n, the motor can be considered as
balanced.
