７は電動機固定子、８は回転子である。 In a conventional submersible electric motor, as shown in FIG. 1, a position detector stator 2 is inserted into the inner diameter of a frame 1 and fixed to the frame 1 by a method such as gluing. Next, after inserting the bracket fixing plate 3,
Attach and remove stop ring 4. After that, the bracket 5 is inserted and the bracket 5 and the bracket fixing plate 3 are tightened and fixed with the fixing bolt 6, and the electric motor is completed. In addition, in Figure 1,
7 is a motor stator, and 8 is a rotor.

なる欠点があつた。 However, with this configuration, the electrical relative position of the position detector stator 2 with respect to the motor stator 7 cannot be adjusted, and the bracket fixing plate 3 is also free within the frame, so when inserting the bolt 6, There was a drawback that it was not easy to catch the screw hole.
Furthermore, since the stop ring 4 is used, the effective usable inner diameter of the frame 1 is reduced, which poses a drawback that becomes a major hindrance when producing an ultra-slim submersible electric motor with an outer diameter of about 2 inches.

本考案は上記従来の欠点に鑑みてなされたもの

る。 The present invention was devised in view of the above-mentioned drawbacks of the conventional art, and makes it possible to manufacture an ultra-slim submersible electric motor with an outer diameter of approximately 2 inches. An embodiment of the present invention will be described below with reference to FIG. Note that functional parts that are the same as those in the conventional configuration described above will be described using the same numbers.

５の同心性は保障される訳である。 In FIG. 2, the frame 1 and the bracket 5 are provided with a spigot part 9 and a threaded part 10, respectively, at the joint between the two. And this pilot part 9
The length relationship between the bracket 5 and the threaded portion 10 is selected so that when the bracket 5 is inserted into the frame 1, the spigot portion 9 is fitted before the threaded portion 10 is engaged. Therefore, although the screws are tightened, the concentricity of the frame 1 and the bracket 5 is guaranteed.

る。 On the other hand, a position detector stator 2 is fixed to the bracket 5 with bolts 6 via mounting fittings 11. Furthermore, the insertion hole for the bolt 6 provided in the bracket 5 is a long hole in the circumferential direction, and when the bolt 6 is loosened, the position detector stator 2 and the mounting bracket 11 rotate only by the length of the bolt hole. This makes it possible to easily finely adjust the electrical relative position with respect to the motor stator 7. Further, since there is no need to use parts such as stop rings that reduce the effective inner diameter of the frame, the inside of the frame with a small diameter can be widely utilized.

以上の様に本考案は外径が２インチ程度以下の
極細型の水中電動機を製造する上で、多大の効果
を発揮するものである。 As described above, the present invention is highly effective in manufacturing ultra-slim submersible electric motors with an outer diameter of about 2 inches or less.
