Problems solved by technology

However, if the rotation of the rotating mechanism is promoted by supplying current from the outside, etc., the input energy will increase, but the efficiency of the rotating mechanism will be reduced.

Embodiment Construction

[0081] Next, embodiments of the present invention will be described with reference to the drawings.

[0082] First, a turning mechanism 100 as a first embodiment (embodiment) will be described with reference to FIGS. 1 to 11 .

[0083] The rotating mechanism generally indicated by reference numeral 100 in FIG. 1 and FIG. magnet4.

[0084] The fixing part 1 is a three-layer structure, in which an upper frame 11, a middle frame 12 and a lower frame 13 are vertically spaced and stacked via eight connecting parts 11b (see FIG. 2).

[0085] Specifically, the upper frame 11 is formed into an equilateral octagonal structure assembled by connecting the ends of eight members 11a having the same cross-sectional shape (channel-shaped cross-section) using a connecting member 11b (see FIG. 1 ).

[0086] Although not explicitly shown in FIG. 1, the middle frame 12 has the same profile as the upper frame 11, and, like the upper frame 11, is formed by making eight members 12a having the sam...

Abstract

The present invention has an obj ect to provide a rotating mechanism with a very high rotation efficiency in which rotation resistance is reduced and rotation is encouraged. It comprises a fixed member (1) having bearings (16, 18) ; a rotary member (2) including a rotary shaft (21) journalled by the bearings and a disk member (22) fixed on the rotary shaft; a plurality of coils (3) which are mounted on the fixed member (1) and arranged at regular intervals on a circle centered on the rotary shaft (21) ; and a first permanent magnet (4) mounted on the disk member (22), wherein first permanent magnets (4) are arranged at regular intervals on a circle centered on the rotary shaft (21) and arranged to face the coils (3).

Description

technical field [0001] The present invention relates to a rotating mechanism constituting a rotating body structure in a generator, an electric machine, etc., and more particularly to such a rotating mechanism having a vertically extending rotating shaft. Background technique [0002] As an example of the rotating mechanism, an electromagnetic rotating machine with a magnetic rotor has been proposed (for example, see Patent Document 1). [0003] Here, the rotation mechanism has various bearings supporting the rotation shaft, and the performance of the rotation mechanism depends on the level of rotation resistance. Therefore, it is necessary to minimize rotational resistance to improve performance or efficiency as a rotational mechanism. [0004] For this reason, it is considered necessary to provide mechanisms to facilitate or facilitate rotation. However, if the rotation of the rotary mechanism is promoted by supplying electric current or the like from the outside, the in...
