This paper discusses the design of a miniature electromagnetic induction type air turbine generator with a multilayer ceramic magnetic circuit. The air turbine is fabricated using a micro electro mechanical systems (MEMS) process, which can form high-accuracy, high-aspect-ratio parts. The magnetic circuit is fabricated using a multilayer ceramic technology that can form a three-dimensional conductor pattern into which a magnetic material can be introduced. By combining these technologies, a miniature generator comprising a miniature magnetic circuit with a helical conductor structure and magnetic core is achieved. In this study, a three-phase and a single-phase generator were fabricated, which produced rotational motion and output waveforms. In this paper, the generators are discussed with respect to the rotational motion and the shape of the magnetic circuit.

This paper presents and discusses the results of the first stage of an ongoing research program to improve the design of wave powered navigation aids using the oscillating water column principle. Wave tank testing has shown that the heave motion of current tail tube buoys is the predominant feature of the hydrodynamic response. A Wells self rectifying air turbine, coupled to a 100-W generator which produces an optimum level of damping to the water column for peak performance, has been designed and tested. It has been concluded from preliminary sea trails that a simple, efficient, reliable, turbine-generator has been developed to meet the requirements of the current design of navigation buoy. However there is considerable scope for improving the hydrodynamic design of wave activated buoys.
