Abstract

In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of 232V was achieved.
