Description
本発明は、モータ防水構造製造方法に関し、特に、モータ固定子外部に複数層の被覆材を被覆し、加熱によって、該被覆材に対し、低融点の被覆層を溶解除去し、及び他方の被覆層を硬化させて、モータ固定子の保護、コスト低減、重量軽減を達成するモータ防水構造製造方法に関する。 The present invention relates to a method for manufacturing a motor waterproof structure, and in particular, a plurality of layers of a coating material is coated on the outside of a motor stator, a coating layer having a low melting point is dissolved and removed from the coating material by heating, and the other coating The present invention relates to a motor waterproof structure manufacturing method in which a layer is cured to achieve protection of a motor stator, cost reduction, and weight reduction.
従来の空冷ファン装置は、発熱部材に対し、送風して強制放熱する最良の選択肢であり、且つ放熱効果も最良であり、通常、ファンフレーム、固定子、及び回転子を備え、該固定子及び回転子は、該ファンフレーム内に装着され、該固定子は、コイル、電磁鋼組及び支持構造を有し、且つ回路板に接続され、該固定子及び該回転子に磁気励起させて、該回転子を回転させるが、該固定子及び回路板は、空気と直接接触し、空気中の水分及び灰塵によって、該部材に湿気及び埃を受けて部材損傷を招き、部材が動作不能になる。 The conventional air-cooling fan device is the best option for blowing and forcibly radiating heat to the heat generating member, and also has the best heat dissipation effect, and usually includes a fan frame, a stator, and a rotor. A rotor is mounted in the fan frame, and the stator has a coil, an electromagnetic steel set and a support structure, and is connected to a circuit board, and magnetically excites the stator and the rotor to Although the rotor is rotated, the stator and the circuit board are in direct contact with air, and moisture and dust in the air receive moisture and dust on the member, causing damage to the member, and the member becomes inoperable.
従来技術は、樹脂充填又は射出成型の方式を採用し、該固定子外部に一層のプラスチックフレームを被覆し、外部の水分及び灰塵による部材への湿気又は埃の侵入を防止するが、この構造は完全とはいえず、樹脂充填又は射出成型方式は、可塑材料を該固定子外部に完全に緊密に貼合被覆し、同時に固定子中の隙間空間を充填し、固定子及び該可塑材料フレームの間に隙間が無いようにするので、固定子が放熱できず、熱の堆積を発生し易く、このため従来技術は、下記欠陥を有する：
１．コストが高い
２．固定子が熱堆積現象を発生し易い
３．重量が重い
The prior art adopts a resin filling or injection molding method, and coats a single plastic frame outside the stator to prevent moisture or dust from entering the member due to external moisture and ash dust. The resin filling or injection molding method is not perfect, but the plastic material is completely tightly bonded and coated on the outside of the stator, and at the same time the gap space in the stator is filled. Since there are no gaps between them, the stator cannot dissipate and heat buildup is likely to occur, so the prior art has the following defects:
1. Cost is high 2. The stator is prone to thermal deposition. Heavy
上記の従来技術の欠陥を解決するため、本発明の目的は、固定子部材を保護し、湿気又は埃を受けることを回避可能なモータ防水構造製造方法を提供することである。 In order to solve the above-described deficiencies of the prior art, an object of the present invention is to provide a motor waterproof structure manufacturing method capable of protecting a stator member and avoiding receiving moisture or dust.
本発明のもう１つの目的は、固定子の熱堆積を回避するモータ防水構造製造方法を提供することである。 Another object of the present invention is to provide a method for manufacturing a motor waterproof structure that avoids thermal deposition of the stator.
本発明の更にもう１つの目的は、被覆材料を節減し、コストを低減可能なモータ防水構造製造方法を提供することである。 It is still another object of the present invention to provide a method for manufacturing a motor waterproof structure that can reduce the coating material and reduce the cost.
上記の目的を達成するため、本発明が提供するモータ防水構造製造方法は、以下のステップを含む：
モータ固定子部材を提供する；
該モータ固定子部材外部を低融点物質からなる第１被覆材で被覆する；
該第１被覆材に更に熱硬化性の材料からなる第２被覆材で被覆し、該第２被覆材は、少なくとも１つの開口を残して、密閉しないようにする；
前記第２被覆材に対し、加熱硬化し、同時に前記第１被覆材を軟化し、該第２被覆材の開口から排出する；
該第２被覆材の開口箇所を密閉する。
In order to achieve the above object, a method for manufacturing a motor waterproof structure provided by the present invention includes the following steps:
Providing a motor stator member;
Coating the outside of the motor stator member with a first coating material made of a low melting point material;
The first coating is further coated with a second coating made of a thermosetting material, the second coating leaving at least one opening and not sealed;
Heat-curing the second coating material, simultaneously softening the first coating material and discharging it from the opening of the second coating material;
The opening portion of the second covering material is sealed.
第１被覆材の配設によって固定子周囲に放熱空間を持たせ、固定子に熱が堆積し難くし、第２被覆材の使用を節減することができ、材料を大幅に節減し、コストを低減し、重量を減少することができ、更に、第１被覆材が熱を受け、熔解して除去回収されることにより繰り返し使用でき、生産コストを大幅低減できる。従って、本発明は、以下の利点を有する：
１．モータ内部に熱を堆積しない
２．コストを低減する
３．重量を減少する
４．モータの使用寿命を延長する
By disposing the first covering material, a heat dissipation space is provided around the stator, heat is hard to accumulate on the stator, the use of the second covering material can be saved, the material is greatly reduced, and the cost is reduced. In addition, the first coating material can be used repeatedly by being heated, melted, removed and recovered, and production costs can be greatly reduced. Accordingly, the present invention has the following advantages:
1. 1. Does not accumulate heat inside the motor. Reduce
