Question
A 6-pole, 24 KW, 120 V, DC machine has a Duplex LAP-woundarmature which has 72
coils with 10 turns per coil. Its rated speed is 2400 RPM. Assume a dead zone of 6 coils that
are always beyondpoles faces. Assume no internal losses in the machine.
Calculate the current per path in the armature ofthis machine if its load is 21.5 Kw.
Select one:
O a. Ipath = 179.17 A
O b. Ipath = 14.93 A
c. None
d. Ipath = 16.167 A
