An eight-pole, 24 KW, 180 V, DC machine has a duplex LAP-wound armature which has 72 coils with 10 turns per coil. Its rated speed is 2400 RPM. Assume a dead zone of 4 coils that are always beyond poles faces. Find the constant K, and the flux per pole to produce 180 V at no-load conditions. Answers The constant K is : The flux per pole is: mWb/pole.
