【考案の詳細な説明】 本案は発電機、特に２分割の固定子鉄心１にコ
イル２を集中巻にした発電機の固定子に関する。[Detailed Description of the Invention] The present invention relates to a generator, and particularly to a stator of a generator in which a coil 2 is concentratedly wound around a two-part stator core 1.

この種の固定子鉄心１は、例えば第１図に示す
ようにコイル巻部１１で２分割１ａ・１ｂして凹
凸係合１１ａ・１１ｂさせ、それと反対側の極片
１２・１２は近接対向させる。 For example, as shown in FIG. 1, this type of stator core 1 is divided into two halves 1a and 1b at a coil winding part 11 and engaged with concave and convex portions 11a and 11b, and pole pieces 12 and 12 on the opposite side are closely opposed to each other. .

又上記固定子鉄心１は例えば第２図鎖線示のよ
うに分割ハウジング３ａ・３ｂ間に挾さみ、磁束
に悪影響を与えないように鉄心１の外周部におい
てボルト４等で締付固定する。 Further, the stator core 1 is sandwiched, for example, between divided housings 3a and 3b as shown by the chain lines in FIG. 2, and secured by tightening bolts 4 or the like on the outer periphery of the core 1 so as not to adversely affect the magnetic flux.

ある。 Therefore, the above-mentioned pole pieces 12 are drawn toward the rotor by magnetic attractive force or the like, and the clearance with the rotor core 5 changes. Alternatively, there may be problems such as misalignment of the laminated steel plates or deformation that tends to open into a fan shape.

本案は上記の問題を簡単な構成により解消する
ことを目的とするもので、上記の２分割鉄心１
ａ・１ｂの相対する極片１２・１２間を合成樹脂

のである。 The purpose of this proposal is to solve the above problem with a simple configuration.
The opposing pole pieces 12 and 1b of a and 1b are connected by a non-magnetic member (stiffener) 6 made of synthetic resin or the like.

させた変形例を示す。 In the example in FIGS. 1 and 2, concave grooves 12a, 12a are formed in the opposing parts of the pole pieces 12, 12, and the concave grooves 12
A rectangular plate-shaped non-magnetic member 6 is engaged and connected between a and 12a. Figure 3 shows the pole piece 12.
12 and the non-magnetic member 6 are wedge-engaged 12b, 12b.
A modified example is shown below.

ある。 7 in the figure shows the stator core 1 in the housings 3a and 3b.
8 is a press-fit hole for the pin 7, 9 is a coil bobbin, and 10 is a rotor coil.

本案は上記の構成であるから、分割鉄心１ａ・
１ｂの両極片１２・１２が非磁性体部材６によつ

生ずる騒音（風切音）を防止することができる等
の効果がある。 Since the present proposal has the above configuration, the split core 1a.
The two pole pieces 12 of 1b are stably connected and held by the non-magnetic member 6, and the pole piece 1 is held by the magnetic attraction force etc.
2 and 12 are not drawn toward the rotor, changing the clearance with the rotor core 5, or preventing misalignment of the laminated steel plates. Misalignment and deformation can be corrected. Further, when the rotor core 5 rotates, it is possible to prevent noise (wind noise) caused by the gap between the pole pieces 12, 12.
