PURPOSE:To contrive to attain the lightweight of a blower by a method wherein magnetic power is generated in the right-angled direction of shaft, and the vane wheels of the blower and the like is directly driven by the power generated as above. CONSTITUTION:A bearing box 10 is installed on a base stand, and the revolving body 2 of a vane wheel and the like is installed through the intermediary of bearings 7 and 9. Then, a permanent magnet 3 is buried on the circumference of the rotating body 2, and the coil 4 whereon a winding 5 was wound around the core is provided at the prescribed position of the bearing box 10. Through these procedures, a shaft joint and the like are unnecessitated, thereby enabling to simplify the construction and to reduce the number of component parts as needed. |
