An eight-pole 25-kw 120-v dc generator has a duplex, Ask an Expert

Engineering

An eight-pole, 25-kW, 120-V dc generator has a duplex lap-wound armature which has 64 coils with 10 turns per coil. Its rated speed is 3600 r/min.

(a) How much flux per pole is required to produce the rated voltage in this generator at no-load conditions?

(b) What is the current per path in the armature of this generator at the rated load?

(d) How many brushes must this motor have? How wide must each one be?

(e) If the resistance of this winding is 0.011 W per turn, what is the armature resistance RA of this machine?
