WebFinal answer. d) A 4-pole DC motor runs at 600rpm at full load on 450 V taking a current of 25 A. Armature is lap-wound with 500 conductors and the flux equation is 0 = 1.7× 10−2 × I0.5wb where I. is the motor current. If the supply voltage and torque are halved, determine the speed at which the motor runs. WebA 4 pole DC shunt generator having a wave winding supplies 50 lamps, each of 60 W at 120 V. The armature and field resistance are 0.2 Ω and 60 Ω respectively. The current in each armature conductor is 11.5 A. 13.5 A. 23 A. 27 A. Total load current IL= 0.5 X 50 = 25 A. A wave winding has two parallel paths.
