摘要

Topic Damage of the system with the frictional and frictional heat which occurs the early starting time is prevented.SolutionsThe center of top and bottom width of the pole 132b where coil 134 of stator 130 is wound and central position of top and bottom width of the permanent magnet 160 which is installed on the inside perimeter aspect of hub 120 inside the range where magnetic force reaches the mechanical difference in level was formed in the top and bottom. In addition, the center of top and bottom width of the pole and is located on the identical line with the center of top and bottom width of the permanent magnet. Differing the length of the top and bottom edge of the pole of the stator, differing the flux density which when it is formed operates the top and bottom edge of the pole when impressing the power source, flux density the center of the permanent magnet that tries moves to the biggest position.
