Insist on the right.

本発明は、機械機器分野に関し、具体的には、電動機固定子、電動機、循環ポンプ、ポンプ輸送装置及び電動機固定子の形成方法に関する。   The present invention relates to the field of mechanical equipment, and specifically relates to an electric motor stator, an electric motor, a circulation pump, a pump transport device, and a method for forming an electric motor stator.

従来技術において、電動機及びその電動機固定子(例えば、循環ポンプの電動機及びその電動機固定子)の構造はさまざまである。図1は従来技術における第1種の電動機及びその電動機固定子の構造を示す図である。図1に示すように、循環ポンプは、電動機とポンプ輸送部品とを含む。電動機は、電動機固定子と電動機回転子とを含む。第1種の電動機の電動機固定子において、コイル10は、回路基板12に溶接固定された後、シールドケース13に納められる。ポンプ輸送部品は、羽根車とポンプケースとを含む。羽根車は、電動機回転子の回転軸の一端に設けられる。ポンプケースは羽根車の外部でカバーして設けられる。電動機固定子とポンプケースはねじによって固定して接続される。   In the prior art, the structure of the electric motor and its electric motor stator (for example, the electric motor of the circulation pump and its electric motor stator) are various. FIG. 1 is a diagram showing a structure of a first type electric motor and its electric motor stator in the prior art. As shown in FIG. 1, the circulation pump includes an electric motor and a pumping part. The electric motor includes an electric motor stator and an electric motor rotor. In the electric motor stator of the first type electric motor, the coil 10 is housed in the shield case 13 after being fixed to the circuit board 12 by welding. The pumping part includes an impeller and a pump case. The impeller is provided at one end of the rotating shaft of the electric motor rotor. The pump case is provided to cover the outside of the impeller. The motor stator and the pump case are fixedly connected by screws.

第1種の電動機において、電動機固定子はシールドケース13を使ってコイル10と回路基板12を保護する。回路基板12が空気中に露出されており、ハンダが錆びて、放熱が不良で、素子が老化してしまう等の欠陥が生じやすくなるため、保護度が低く、温度変化によって水蒸気等が発生しやすく、回路基板12の安全を確実に保証することができない。回路基板12とコイル10がハンダのみを介して固定され、外力を受けると緩んで切断されやすいので、信頼性が低い。電動機が運転する際、シールドケース13も振動しやすく、電動機の運転に影響を与えてしまう。   In the first type electric motor, the electric motor stator protects the coil 10 and the circuit board 12 using the shield case 13. Since the circuit board 12 is exposed to the air, the solder is rusted, heat dissipation is poor, and defects such as aging of the element are likely to occur, so the degree of protection is low and water vapor is generated due to temperature changes. It is easy to ensure the safety of the circuit board 12 with certainty. Since the circuit board 12 and the coil 10 are fixed only by soldering and are loosened and easily cut when subjected to an external force, the reliability is low. When the electric motor is operated, the shield case 13 is also likely to vibrate, which affects the operation of the electric motor.

第1種の電動機及びその電動機固定子の上述した欠陥を解消するため、従来技術において第2種の電動機及びその電動機固定子の構造を提示した。
図2は、従来技術における第2種の電動機及びその電動機固定子の構造を示す図である。図2に示すように、第2種の電動機の電動機固定子において、コイル1a'と回路基板1b'は溶接して固定された後、熱硬化性材料1c'によって一体に射出成型されて電動機固定子1'の主な部分を構成している。
In order to eliminate the above-described defects of the first type electric motor and its electric motor stator, the structure of the second type electric motor and its electric motor stator was presented in the prior art.
FIG. 2 is a diagram showing a structure of a second type electric motor and its electric motor stator in the prior art. As shown in FIG. 2, in the electric motor stator of the second type electric motor, the coil 1a ′ and the circuit board 1b ′ are fixed by welding and then injection-molded integrally with a thermosetting material 1c ′. It constitutes the main part of the child 1 '.

図3は従来技術において循環ポンプが第2種の電動機及びその電動機固定子を含む構造を示す図である。図3に示すように、循環ポンプは、電動機とポンプ輸送部品とを含む。電動機は、電動機固定子1'と電動機回転子2'とを含む。該電動機の電動機固定子1'において、コイル1a'と回路基板1b'は溶接して固定された後、熱硬化性材料1c'によって一体に射出成型されている。ポンプ輸送部品は、羽根車3'とポンプケース5'とを含む。羽根車3'は電動機回転子2'の回転軸の一端に設けられる。ポンプケース5'は、羽根車3'の外部でカバーして設けられる。電動機固定子1'とポンプケース5'はねじ4'によって固定して接続される。   FIG. 3 is a diagram showing a structure in which a circulation pump includes a second type electric motor and its electric motor stator in the prior art. As shown in FIG. 3, the circulation pump includes an electric motor and a pumping part. The electric motor includes an electric motor stator 1 ′ and an electric motor rotor 2 ′. In the motor stator 1 ′ of the motor, the coil 1 a ′ and the circuit board 1 b ′ are fixed by welding and then integrally molded with a thermosetting material 1 c ′. The pumping part includes an impeller 3 'and a pump case 5'. The impeller 3 ′ is provided at one end of the rotating shaft of the electric motor rotor 2 ′. The pump case 5 ′ is provided so as to cover the outside of the impeller 3 ′. The motor stator 1 ′ and the pump case 5 ′ are fixedly connected by screws 4 ′.

本発明を実現する過程において、発明者は、第2種の電動機固定子によると第1種の電動機及びその電動機固定子に存在する上述した問題を解決することができるが、第2種の電動機及びその電動機固定子の構造に新しい技術課題があることを発現した。射出成型中に射出圧が大きいので、回路基板1b'にある程度の衝撃を与え、且つ金型及び射出材料の温度が回路基板1b'上の電子素子を損害し、回路基板1b'の使用の安定性に影響を与える恐れがあって、ひいては回路基板1b'が失効化されるリスクがあるため、電動機の合格率又は寿命を低下させてしまう。実際の使用中に、回路基板1b'がコイル1a'の温度上昇及び液体の温度の影響を受けやすく、電子素子の性能を低下させ、電動機の寿命を短縮させてしまう。   In the process of realizing the present invention, the inventor can solve the above-mentioned problems existing in the first type electric motor and the electric motor stator according to the second type electric motor stator. And there was a new technical problem in the structure of the motor stator. Since the injection pressure is large during injection molding, a certain degree of impact is given to the circuit board 1b ', and the temperature of the mold and the injection material damages the electronic elements on the circuit board 1b', and the use of the circuit board 1b 'is stable. The circuit board 1b 'may be invalidated because of a risk of affecting the performance, and thus the pass rate or life of the motor is reduced. During actual use, the circuit board 1b ′ is easily affected by the temperature rise of the coil 1a ′ and the temperature of the liquid, which degrades the performance of the electronic element and shortens the life of the motor.

また、電動機固定子の回路基板1b'とコイル1a'が一緒に密封されているので、伝熱面積が大きく、伝熱効率が早いので、回路基板1b'が輸送中の液体の温度とコイル1a'の温度上昇の影響を受けやすく、特に、循環ポンプを高温の液体に応用する際の影響が顕著であって、循環ポンプの電力消費が大きく、高温まで上昇するなどの問題が存在し、循環ポンプの寿命をひどく短縮させてしまう。   Further, since the circuit board 1b ′ and the coil 1a ′ of the electric motor stator are sealed together, the heat transfer area is large and the heat transfer efficiency is fast. Therefore, the circuit board 1b ′ is connected to the temperature of the liquid being transported and the coil 1a ′. The circulation pump is particularly affected when the circulation pump is applied to a high-temperature liquid, and there are problems such as high power consumption of the circulation pump and rising to a high temperature. Will severely shorten the lifespan.
