Formula for cancellation of reactance voltage on an average basis using interpoles ________ Nc = Lc (dic/dt) = Lc (2lc/tc) b) Nc = Lc (dic/dt) = Lc (2lc/tc) c) 2 Nc = Lc (dic/dt) = Lc (lc/tc) d) Cannot be determined

Formula for cancellation of reactance voltage on an average basis using interpoles ________ Nc = Lc (dic/dt) = Lc (2lc/tc) b) Nc = Lc (dic/dt) = Lc (2lc/tc) c) 2 Nc = Lc (dic/dt) = Lc (lc/tc) d) Cannot be determined Correct Answer 2 Nc = Lc (dic/dt) = Lc (2lc/tc)

2 Nc = Lc (dic/dt) = Lc (2lc/tc). With Bi determined by above equation, the ampere-turns needed to cancel the armature reaction ampere-turns and then to create the necessary flux density are given by, ATi = ATa (peak)+(Bi/µ0 )lgi
