EKE SAMUEL | 29 pages (8522 words) | Projects



This study deals with the design, construction and performance evaluation of 1000W (1KVA) fuelless power generating set to serve as an alternative source of energy. The materials used for the project work included c motor, alternator, connecting shaft, coupling, 12V/75Ah battery, charging panel (Transformer, diode, and capacitor), and frame. The methods involved fabrication of a connecting rod with boring of a reasonable hole that was conveniently fitted into the DC motor with threaded hole for bolting. The crank casing of the alternator was inserted and the armature of the alternator was fixed. The generator frame was then constructed to provide support and rigidity. The diode was connected to green cables and capacitors to the yellow cable. The terminal of the DC motor was connected to the battery, with red cables to the mains as output. The machine consists of five different units; the power supply, conversion, control, output and charging units. The components parts includes 12V battery, D.C motor, alternator, connecting shaft, bolts and nuts, transformer, diode, and noise damper. The result of the performance evaluation of the fuel-less power generating set shows that the machine has an average efficiency of 56.43% at load of 600W for continuous operation. The peak efficiency of the constructed fuel-less power generating set was 89.1% at load of 100W. For comparison, the result obtained from Power inverter, has clearly confirmed that the highest efficiency recorded is at 96.27% which is more than that of the fuel-less power generating set which is at 89.1%, at a load of 100W respectively.
