A compound generator has a lap-wound armature with 12 slots and 4 turns per coil. At no- load, flux per pole is 0.5Wb and it is running at 900 rpm. Shunt resistance is 1002, series field resistance is 30, and armature resistance is 0.52. Calculate induced voltage, armature current and terminal voltage at no-load. i) If a 1002 load is connected to the terminals and the series flux is added to the shunt flux such that it remains the same as it was at no-load, calculate the terminal voltage, armature current, and power dissipated in the load.

Draw the circuit
Transcribed Image Text:A compound generator has a lap-wound armature with 12 slots and 4 turns per coil. At no-
load, flux per pole is 0.5Wb and it is running at 900 rpm. Shunt resistance is 100N, series field
resistance is 30, and armature resistance is 0.52.
(i)
Calculate induced voltage, armature current and terminal voltage at no-load.
(ii)
If a 1002 load is connected to the terminals and the series flux is added to the shunt
flux such that it remains the same as it was at no-load, calculate the terminal voltage,
armature current, and power dissipated in the load.
