本発明は、電動機の温度保護装置の固定構造に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fixing structure for a temperature protection device for an electric motor.
従来の技術
電動機の温度保護装置は、最も過熱することが多い巻線
部に固定される。Prior Art Temperature protection devices for electric motors are fixed to the windings that most often overheat.
この主巻線と補助巻線を並列接続する電動機にあっては

を接続するプリント基板を備えた固定子構造の電動機が
現出している。Some electric motors in which a main winding and an auxiliary winding are connected in parallel have windings around a stator core having a large number of teeth protruding toward the inner diameter. However, this type of electric motor
Since there are many slots formed between the teeth of the stator and it is difficult to attach the main winding and auxiliary winding to these slots, it is difficult to install the main winding and the auxiliary winding in the iron core as disclosed in Japanese Patent Application Laid-Open No. 63-299750. In an electric motor that has multiple windings and connects the windings to each other, the inner diameter side of the iron core is connected and integrated, and a radial magnetic path is formed on the outer diameter side, and the winding is applied to this magnetic path. An electric motor having a stator structure has been developed, which is equipped with a bobbin that is attached with a bobbin, a terminal is formed on the side surface of the bobbin to connect the legs of the winding, and a printed circuit board is connected to the terminal.
このような従来の固定子構造の電動機の温度保護装置の
固定方法について第２図、第３図により説明する。A method of fixing a temperature protection device for a motor having a conventional stator structure will be explained with reference to FIGS. 2 and 3.
図において温度保護装置１を縛り糸２又は接着剤３を用
いて巻線４の表面上に固定するもので、コイルボビン５
に巻装される巻線４のボリュウムの増減に対し柔軟に対
応、できるようにしている。In the figure, a temperature protection device 1 is fixed on the surface of a winding 4 using a binding thread 2 or an adhesive 3, and a coil bobbin 5
This makes it possible to flexibly respond to increases and decreases in the volume of the winding 4 wound on the wire.
また、第３図のようにプリント基板６に温度保護袋Ｍ１
を固定し、巻線４の表面との間で挟持している。Also, as shown in Fig. 3, a temperature protection bag M1 is attached to the printed circuit board 6.
is fixed and held between the surface of the winding 4.
発明が解決しようとする課題
しかしこれらの方法では、温度保護装置を保持するため
に縛り糸を使うと製造の工数が増大する。Problems to be Solved by the Invention However, in these methods, the use of tie strings to hold the temperature protection device increases the number of manufacturing steps.
また、プリント基板と巻線の外周との間にはさみ込む方
法では巻線のコイルボリュウムの増減に対応できない。Furthermore, the method of sandwiching the coil between the printed circuit board and the outer periphery of the winding cannot cope with increases and decreases in the coil volume of the winding.
そのために接着剤を用いることも考えられるが、硬化時
間や巻線の温度上昇時の高温下での固着力低下、接着剤
が巻線、玉軸受を腐食してしまうと言う問題と、更には
温度保護装置の動作を正しく行わせるために、温度保護
装置の接着箇所が制限されると言う問題があった。It is possible to use adhesives for this purpose, but there are problems such as curing time, decrease in adhesion strength at high temperatures when the temperature of the windings increases, and the adhesive corroding the windings and ball bearings. There has been a problem in that in order to ensure the correct operation of the temperature protection device, the locations where the temperature protection device can be bonded are limited.
本発明は上記問題点に鑑み、縛り糸や接着剤を用いず、
コイルボリュウムの増減にも容易に対応できる温度保護
装置の固定構造を提供するものである。In view of the above problems, the present invention does not use tying strings or adhesives,
The present invention provides a fixing structure for a temperature protection device that can easily respond to increases and decreases in coil volume.
課題を解決するための手段
本発明は、固定子の軸方向端面に対向して配役されるプ
リント基板と、このプリント基板に固定された弾性を有

。Means for Solving the Problems The present invention provides a printed circuit board disposed opposite to an axial end surface of a stator, an elastic resin fixed to the printed circuit board, and a temperature protection device held by the resin. The temperature protection device is brought into contact with the surface of the stator winding, and the terminals provided on the coil bobbin of the stator are fixed to a printed circuit board to sandwich the temperature protection device.
作用
弾性を有する樹脂は温度保護装置を適当な力で巻線に付

いような場合ｌこもこの弾性を有する樹脂により適当な
力で巻線に当接挟持されるので温度保護装置にダメージ
を与えることなく、巻線表面の温度を正確に感知する。The resin with acting elasticity biases the temperature protection device against the winding with an appropriate force. In addition, when there is a large amount of windings and the distance from the printed circuit board is small, the elastic resin allows the windings to be held in contact with the windings with an appropriate force, without damaging the temperature protection device. Accurately senses surface temperature.

板に固定している。In FIG. 1, a temperature protection device 1 is fixed and held by an elastic resin 7 fixed to a printed circuit board 6, and is attached to a coil bobbin 5 such that the surface of a winding 4 applied to a coil bobbin 5 of a stator comes into contact with the coil bobbin 5. A terminal 5a provided at 5 is fixed to a printed circuit board.

The increase or decrease in the distance between the printed circuit board 6 and the surface of the winding 4 due to this is adjusted by adjusting the insertion length of the terminal 5a. As a result, the temperature protection device 1
is always applied to the surface of the winding 4 with an appropriate pressing force, and without causing mechanical damage to the temperature protection device 1 (it is held accurately and the temperature of the winding 4 is accurately detected). can do.
