DIRECT-DRIVEN MAGNETIC FORCE ROTARY DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem of a fan to which a direct-driven magnetic rotary device is applied wherein a loss is generated during the process for transmitting a rotating force because a rotator and a motor exist independently and that reduction in size is difficult. SOLUTION: A small and efficient direct-driven magnetic rotary device is realized at a low cost by fixing a permanent magnet plate directly to a rotator thereby eliminating a rotating force transmitting means.
