Q. A dc shunt machine has an armature winding resistance of 0.12 and a shunt-?eld winding resistance of 50 . The machine may be run on 250-V mains as either a generator or a motor. Find the ratio of the speed of the generator to the speed of the motor when the total line current is 80 A in both cases.
The aim of this project is to design, construct and build a motorised base driven by two small dc motors. The motor drives are two H-bridges. The switching devices in these bridges
