Energy of mechanical vibration is not used
effectively. The linear generator is considered to generate
electrical energy from various mechanical vibrations. This
experimental device consists of a mechanical vibration
generation part and a linear generation one. Various
vibrations are measured and reproduced in the vibration
generation part. And this mechanical vibration generator is
connected to the mover of the linear generator. To improve
the efficiency of the linear generator, design of the field
magnet and the stator coil of are studied by numerical
analysis. The linear generator using the improved
configuration shows better characteristics than the previous
one.
