Abstract

PURPOSE:To provide a stabilized holding of the shaft promoting an improvement of the efficiency with a work of assembly simplified as well, by making an assembly in such manner that a tube-shaped unit at the stator side, supporting the stator wiht the rotating shaft being the center, be inserted into a tube-shaped unit at the rotor side, supporting the permanent magnet as a rotating unit.
