In this paper, the design criteria, assembly practices and experimental analysis of a low cost micro generation system are presented. A high-power density microturbine is specially devised using a stock automotive turbocharger. The project concept is evolved to achieve satisfactory operating conditions. The main practical challenges to achieve the desirable output performance are discussed from the electromechanical perspective including an extensive vibration analysis during operation. The balancing procedure is proven to be a keystone requirement for safe operation at higher rotational speeds. Characterizing the electromechanical interaction between the components is a crucial requirement in the design process. The microturbine is tested using steady inlet compressed air flow, with accelerometers installed on each bearing. The described design and assembly procedures allow the unloaded microturbine to run safely up to 100000 rpm.
