本考案はモータの保護装置、さらに詳しくは塩
分の混入を防止するためのモータの保護装置に関
する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a motor protection device, and more particularly to a motor protection device for preventing salt from entering.
モータはさまざまな環境下で使用されている
が、例えば臨海地区のように空気中の塩分濃度が
高い地域にあつては、モータに塩分が混入しやす
いため、モータの駆動効率の低下やモータ巻線の
焼損といつた不都合な事態が起こりやすく、その
対策が求められていた。
Motors are used in a variety of environments, but in areas with high salt concentrations in the air, such as coastal areas, it is easy for salt to get into the motor, leading to a decrease in motor drive efficiency and motor winding. Inconvenient situations such as line burnout are likely to occur, and countermeasures are needed.
従来、この種の問題を考慮したモータとして

ことができないという難点があつた。 Conventionally, as a motor that takes this kind of problem into consideration, there is a dust-proof clutch motor as disclosed in Japanese Patent Application Laid-Open No. 50-79707. The problem was that it could not be used if it was already installed.
本考案は上記の点に鑑みてなされたものであ

とができるモータの保護装置を提供するにある。
The present invention was made in view of the above points, and its purpose is to provide a motor protection device that can prevent salt from entering the motor and can be easily installed on existing motors. .
この目的を達成するために、本考案者らは、ま

討を重ねた結果、塩分はNa+とCl-とにイオン化

で化学的に塩分が吸着でき、モータの冷却効率を
低下させる必配もないということを見い出した。
To achieve this objective, the present inventors first developed a commonly known method for removing salt from the air.
In other words, we considered a method of mechanically adsorbing salt by passing air through small holes, but this method could not be considered suitable because it risked reducing the cooling efficiency of the motor. As a result of further investigation, we focused on the fact that salt is ionized into Na + and Cl - , and if we create a filter using substances charged with + and -, the filter will chemically eliminate salt. It has been found that it can be adsorbed and there is no need to reduce the cooling efficiency of the motor.
すなわち、本考案は、モータの冷却扇の吸気口
に、永久的に分極した物質から成るフイルタを取
り付けたことを特徴とするものである。 That is, the present invention is characterized in that a filter made of a permanently polarized substance is attached to the intake port of the cooling fan of the motor.
以下、本考案の実施例を第１図に基づいて説明
する。
Hereinafter, an embodiment of the present invention will be described based on FIG.

その冷却扇の吸気口、４は該吸気口３に取り付け

的に分極した不織のポリプロピレンから成る。 FIG. 1 is an exploded perspective view showing an embodiment of the present invention, in which reference numeral 1 is a motor, 2 is a drive shaft thereof, 3 is an intake port of the cooling fan, and 4 is a filter attached to the intake port 3. The filter 4 is made of permanently polarized non-woven polypropylene.

タにも簡単に取り付けることができ、フイルタ４
自体の交換も容易である。 If the filter 4 made of a permanently polarized substance is attached to the intake port 3 in this way, as described above, salt in the air will be chemically adsorbed by the filter 4, so that it will not be absorbed into the inside of the motor 1. There is no need to worry about salt contamination. In addition, this filter 4 can be easily attached to an existing motor.
It is also easy to replace itself.

痕跡は認められなかつた。 In order to confirm the effectiveness of the filter 4, the present inventors targeted five existing elevators in coastal areas that had previously caused accidents due to salt contamination. After removing the salt in the motor, I installed a new filter 4 and operated it for a year. After one year of operation with the filter 4 attached, each motor was disassembled and the interior was examined, and no trace of salt intrusion was found in any of the motors.

As explained above, according to the present invention, by attaching a filter made of a permanently polarized substance such as polypropylene to the intake port of the motor,
Salt in the air is chemically adsorbed by the filter,
As a result, motor performance deterioration and accidents caused by salt contamination can be prevented, and the filter has the advantage that it can be easily installed on existing motors. It is possible to provide a motor protection device with additional functions.
