Research and development of the electric supercharger for minivehicles

If same degree-of-comfort coefficient (start dash power, passing, and gradability) as a subcompact is securable by car, where the body is light as global environment problems and energy conservation measures, the large energy saving effect is expectable. For this reason, this paper performed basic research of a short time (5 or less sec) the economical electric supercharger of a special designed, one. As a result, small & ultra high-speed electric supercharger development is in prospect, without using an unstable rare earth permanent magnet at an expensive price and economically.
