Abstract
PURPOSE: To heighten the magnetic flux density, by providing inside magnetic poles between a permanent magnet and moving magnetic poles and defining a gap between the inside magnetic poles and the moving magnetic poles to concentrate the magnetic flux of the permanent magnet by the gap.
CONSTITUTION: The inside magnetic poles 30 made of soft magnetic substance such as iron are provided between the permanent magnet 21 and the moving magnetic poles 22. The inside magnetic poles are in contact with the permanent magnet 21. The small gap is defined between the inside magnetic poles 30 and the moving magnetic poles 22. Thus, the magnetic flux of the permanent magnet 21 can be concentrated by the gap to raise the density of the magnetic flux.
