Description

本発明は家電用各種機器、空調用各種機器に用いられるモールドモータに関する。  The present invention relates to a molded motor used in various appliances for home appliances and various appliances for air conditioning.

従来、モールドモータは、特開平8−280160号公報に記載されたものが知られている。図5,図6は従来のモールドモータの構造を示す平面図及び側面図である。  Conventionally, a mold motor described in JP-A-8-280160 is known. 5 and 6 are a plan view and a side view showing the structure of a conventional molded motor.

図5に示す従来のモールドモータ110は、モールド樹脂による一体成型(以後の説明では、モールド成型と称す)前の構成を示す図で、ステータ112の上面にモータドライバIC122を実装したプリント配線板120を配し、プリント配線板120のIC122をステータ112の鉄心114の外周部に設けた挿入溝124に取り付けたものである。ステータ112には巻線116が施してあり、巻線端は、プリント配線板120のA部にて巻き付けた上、はんだ付けすることにより、プリント配線板120と巻線116は、電気的接続を行うよう構成している。   A conventional molded motor 110 shown in FIG. 5 is a diagram showing a configuration before integral molding with mold resin (hereinafter referred to as mold molding), and a printed wiring board 120 having a motor driver IC 122 mounted on the upper surface of a stator 112. The IC 122 of the printed wiring board 120 is attached to the insertion groove 124 provided in the outer peripheral portion of the iron core 114 of the stator 112. The stator 112 is provided with a winding 116. The end of the winding is wound at part A of the printed wiring board 120 and then soldered, whereby the printed wiring board 120 and the winding 116 are electrically connected. Configured to do.

図6は、従来のモールドモータのモールド成型後の側面図であり、モールド樹脂130により、巻線116を施し、プリント配線板120を上面に配したステータ全体をモールド成型したものである。モールド樹脂には、樹脂成形温度が熱可塑性樹脂に比べて比較的低くプリント配線板に実装するモータドライバICを含めた各種電子部品へのダメージが少ない、不飽和ポリエステルに代表される熱硬化性樹脂が広く一般に使用されている。   FIG. 6 is a side view after molding of a conventional mold motor, in which a winding 116 is applied with a mold resin 130 and the entire stator with the printed wiring board 120 disposed on the upper surface is molded. The mold resin has a relatively low resin molding temperature compared to thermoplastic resins, and is less damaging to various electronic components including motor driver ICs mounted on printed wiring boards. Is widely used in general.

このようにステータや巻線等をモールド成型することで、ステータに発生する鉄や、巻線に発生する銅損による熱をモールド樹脂に拡散して、ステータや巻線の温度上昇を抑制できる効果が得られるために、モールドモータは、家電用機器などに広く使用されている。

JP-A-8-280160

しかしながら、この従来のモールドモータにおいては、モータドライバIC等各種電子部品をはんだ付け実装したプリント配線板を含めてモールド成型するため、種々の課題が発生している。   However, since this conventional molded motor is molded including a printed wiring board on which various electronic components such as a motor driver IC are soldered and mounted, various problems occur.

課題の一つは、プリント配線板上のドライバIC等各種電子部品のはんだ付け部に対する影響である。はんだ付けのトラブルの一つとして、「はんだクラック」が良く知られており、その要因がはんだ付け部への応力集中であることも周知の事実である。モールドモータに使用されるモールド樹脂は、モータの構造物を成すものであり、当然頑強で硬いことが要求される。しかしながら、モールド成型時の熱や成型圧力により、少なからずモールド成型されたプリント配線板のはんだ付け部には応力が作用し、成型後の冷熱時にも応力の残存がある。   One of the problems is the influence on the soldered portion of various electronic components such as a driver IC on the printed wiring board. As one of the soldering troubles, “solder crack” is well known, and it is a well-known fact that the cause is stress concentration on the soldered portion. Mold resin used for the mold motor constitutes the structure of the motor, and is naturally required to be strong and hard. However, due to heat and molding pressure at the time of molding, stress acts on the soldered portion of the printed wiring board that has been molded, and there is residual stress even during cooling after molding.

また、プリント配線板に使用される部品としてモータドライバICやトランジスタ、電力抵抗のような発熱部品であれば、モータ運転時に発生する熱により形状寸法の変化が起きるときには、モータドライバIC等各種電子部品周辺が頑強なモールド樹脂に包まれているため、形状寸法変化の応力が、モールド樹脂に比べ比較的弱いはんだ付け部に集中し、形状変化の後、はんだクラックに至って断線する可能性が高くなる。   In addition, if the parts used in the printed wiring board are heat generating parts such as motor driver ICs, transistors, and power resistors, various electronic parts such as motor driver ICs can be used when the shape and dimension changes due to heat generated during motor operation. Since the periphery is encased in a strong mold resin, the stress due to the change in shape and dimension is concentrated on a relatively weak soldering part compared to the mold resin, and after the change in shape, there is a high possibility of breakage due to a solder crack. .

このようなはんだクラックのトラブルを防ぐためにはモールド成型するプリント配線板の基材を、紙フェノール材から、エポキシ材やコンポジット材等高価なものを使用したり、はんだランドを大きくしてはんだ量を多くする等が必要である。   In order to prevent such problems of solder cracks, the printed wiring board substrate to be molded can be made of paper phenolic materials, such as expensive materials such as epoxy materials and composite materials, or solder lands can be enlarged to reduce the amount of solder. It is necessary to increase it.

また、課題の一つは、モールド成型されるプリント配線板に使用する電子部品として、アルミ電解コンデンサを自由に選択できないということである。アルミ電解コンデンサは、構造上電解液がコンデンサの電極付近から徐々にわずかに蒸発してガスとなってコンデンサ外部へ漏れて大気に拡散することは周知の事実である。アルミ電解コンデンサがモールド成型されると、漏れ出たガスは大気には拡散せず、コンデンサ電極付近に滞留することになる。コンデンサから漏れ出たガスには導電性が在るため、結果的にコンデンサの電極間が短絡する故障を生じる危険性がある。これの対策としては、アルミ電解コンデンサの封止方法を樹脂封止等特殊なものにする必要があり、高価になる。   Moreover, one of the problems is that an aluminum electrolytic capacitor cannot be freely selected as an electronic component used for a printed wiring board to be molded. It is a well-known fact that an aluminum electrolytic capacitor has a structure in which an electrolyte gradually evaporates slightly from the vicinity of the electrode of the capacitor, becomes a gas, leaks outside the capacitor, and diffuses into the atmosphere. When the aluminum electrolytic capacitor is molded, the leaked gas does not diffuse into the atmosphere but stays in the vicinity of the capacitor electrode. Since the gas leaking from the capacitor has conductivity, there is a risk of causing a failure in which the electrodes of the capacitor are short-circuited as a result. As a countermeasure against this, it is necessary to make the sealing method of the aluminum electrolytic capacitor special, such as resin sealing, which is expensive.

また、課題の一つは、最近特に強く求められているリサイクル性である。モールドモータは、当然工業製品であり、時代の趨勢から高いリサイクル性が、その他の製品同様要望されてきている。   One of the issues is recyclability, which has been particularly strongly demanded recently. Mold motors are naturally industrial products, and high recyclability has been demanded in the same way as other products due to the trend of the times.

プリント基板までもモールド成型する場合、モールド成型時の電子部品へのダメージを考慮すると、例えばモータドライバICの場合、保存周囲温度の保証最大温度が150℃のため、成型温度が約150℃である比較的温度の低い熱硬化性樹脂を用いる以外にない。   In the case of molding even a printed circuit board, considering the damage to electronic components during molding, for example, in the case of a motor driver IC, the guaranteed maximum temperature of storage ambient temperature is 150 ° C., so the molding temperature is about 150 ° C. There is nothing but to use a thermosetting resin having a relatively low temperature.

しかしながら、熱硬化性樹脂は、硬化時の高温下では流動するものの、その時の架橋反応により硬化した後は加熱しても流動化しない。このためリサイクル処理時には、粉砕後、分別処理して資源を回収する以外にない。しかしながら、各種電子部品が実装されたプリント配線板がモールド樹脂に含まれているため、金属材料を除いた樹脂材料の分別とリサイクルは困難であり、モールドモータのリサイクル率を低下させる大きな要因となっている。   However, although the thermosetting resin flows at a high temperature at the time of curing, it does not flow even when heated after being cured by the crosslinking reaction at that time. For this reason, at the time of the recycling process, there is no other way but to collect resources after the pulverization and separation. However, since the printed wiring board on which various electronic components are mounted is included in the mold resin, it is difficult to separate and recycle the resin material excluding the metal material, which is a major factor for reducing the recycling rate of the molded motor. ing.

その他にも、この従来のモールドモータにおいては、ステータに施した巻線とプリント配線板との接続においては、工数が大となるという課題がある。   In addition, in this conventional molded motor, there is a problem that man-hours are increased in the connection between the winding applied to the stator and the printed wiring board.

図7は、図6のA部の拡大図であるが、図に示す通り、プリント配線板の張り出し部に巻線116を巻き付けてはんだ付けしているが、巻線を巻き付ける作業に時間を要し、また巻線116の巻き付けとその後のはんだ付け作業を自動化するには、特別の装置を要することは言うまでもない。   FIG. 7 is an enlarged view of part A in FIG. 6. As shown in the figure, the winding 116 is wound around the overhanging portion of the printed wiring board and soldered. However, it takes time to wind the winding. Needless to say, a special device is required to automate the winding of the winding 116 and the subsequent soldering operation.

従来のモールドモータにおいては、これらの課題解決が強く求められている。本発明は、モータドライバIC等各種電子部品をはんだ付け実装したプリント配線板をモールド成型しないことにより、上述の課題を解決するだけでなく、モールド成型されたステータ巻線組立へのプリント配線板の取り付け構造に配慮し、かつステータ巻線組立とプリント配線板との電気的接続に工夫を凝らして、相互の電気的接続を容易ならしめたモールドモータを提供することを目的とする。   Conventional mold motors are strongly required to solve these problems. The present invention not only solves the above-mentioned problems by not molding a printed wiring board on which various electronic components such as a motor driver IC are soldered and mounted, but also allows the printed wiring board to be molded into a stator winding assembly. It is an object of the present invention to provide a molded motor in which the mounting structure is considered and the electrical connection between the stator winding assembly and the printed wiring board is devised to facilitate the mutual electrical connection.

上記課題を解決するために、本件出願に係る発明のモールドモータは、ステータと、巻線と、インシュレータとからなるステータ巻線組立部を構成して、さらに、前記ステータ巻線組立部に前記巻線の巻線端が接続される導電性PINを設けて、この導電性PINの一部が露出されるように前記ステータ巻線組立部をモールド樹脂部で覆い、前記導電性PINの露出した一部にプリント配線板を固定することにより前記ステータ組立部とプリント配線板とを固定し、かつ巻線と前記プリント配線板との電気接続が行なわれるモールドモータであり、前記導電性PINに前記巻線の巻線端が接続される箇所と、この導電性PINの前記モールド樹脂部から露出させる箇所とが異なる箇所であることを特徴とする。   In order to solve the above-described problems, a molded motor according to the present invention includes a stator winding assembly portion including a stator, a winding, and an insulator, and further, the winding is wound around the stator winding assembly portion. A conductive PIN to which the winding end of the wire is connected is provided, the stator winding assembly is covered with a mold resin portion so that a part of the conductive PIN is exposed, and the conductive PIN is exposed. A molded motor in which the stator assembly and the printed wiring board are fixed by fixing the printed wiring board to a portion, and electrical connection between the winding and the printed wiring board is performed, and the winding is wound around the conductive PIN. The location where the winding end of the wire is connected is different from the location exposed from the mold resin portion of the conductive PIN.

本発明によれば、巻線に発生する銅損、ステータに発生する鉄損をモールド樹脂に拡散してステータ巻線組立の温度上昇を抑制する効果と、合わせてプリント配線板の電子部品のはんだ付け部にモールド成型時のストレスが作用せず高信頼性であること、またプリント配線板を紙フェノール材等安価な材料が使用可能であること、電子部品がモールド樹脂で包まれることがないので、安価なアルミ電解コンデンサをプリント配線板に使用可能で
あること、またプリント配線板をモールド樹脂で包むことをしないので、モールドモータを、ブラケット、プリント配線板、ロータ、ステータ組立の4つに直ちに分解できてリサイクル性が優れるという効果が得られる。
According to the present invention, the copper loss generated in the winding and the iron loss generated in the stator are diffused into the mold resin to suppress the temperature rise of the stator winding assembly, and the solder of the electronic component of the printed wiring board is combined. Because stress at the time of molding does not act on the attachment part, it is highly reliable, inexpensive materials such as paper phenolic materials can be used for the printed wiring board, and electronic parts are not wrapped with mold resin Since an inexpensive aluminum electrolytic capacitor can be used for a printed wiring board, and the printed wiring board is not wrapped with a mold resin, the mold motor is immediately attached to the bracket, the printed wiring board, the rotor, and the stator assembly. The effect that it can decompose | disassemble and is excellent in recyclability is acquired.

更に、プリント配線板をモールド成型しないことにより、モータドライバIC等各種電子部品による温度制約が無く、成型温度が比較的低い熱硬化性樹脂だけでなく、成型温度が高い熱可塑性樹脂でも使用可能である。熱硬化性樹脂、熱可塑性樹脂のいずれでも可能になる。   Furthermore, by not molding the printed wiring board, there are no temperature restrictions due to various electronic components such as motor driver ICs, and it is possible to use not only thermosetting resins with relatively low molding temperatures but also thermoplastic resins with high molding temperatures. is there. Either a thermosetting resin or a thermoplastic resin can be used.

また、本発明によれば、プリント配線板を、モールド成型されたステータ巻線組立に容易に取り付け、固定できる効果を有し、プリント配線板をステータ巻線組立に取り付け、固定する作業の自動化も可能にする効果が得られる。   In addition, according to the present invention, the printed wiring board can be easily attached to and fixed to the molded stator winding assembly, and the work of attaching and fixing the printed wiring board to the stator winding assembly can be automated. The effect to make possible is obtained.

また、本発明によれば、プリント配線板とステータ巻線組立の巻線との電気的接続の作業を容易にするもので、電気的接続時に自動はんだ機を用いることで、はんだ付け作業の合理化も可能になる効果が得られる。   Further, according to the present invention, the electrical connection work between the printed wiring board and the windings of the stator winding assembly is facilitated, and the soldering work is rationalized by using an automatic soldering machine at the time of the electrical connection. The effect that becomes possible is also obtained.

また、本発明によれば、熱可塑性樹脂の場合、成型に要する時間は、熱硬化性樹脂に比べ極めて早い特徴を有し、工数の削減に貢献できるだけでなく、加熱により再び流動化する性質から樹脂自体がリサイクル性に優れるという効果もある。   Further, according to the present invention, in the case of a thermoplastic resin, the time required for molding has an extremely fast characteristic as compared with a thermosetting resin, which not only contributes to the reduction of man-hours but also from the property of fluidizing again by heating. There is also an effect that the resin itself is excellent in recyclability.

発明のモールドモータは、ステータと、巻線と、インシュレータとからなるステータ巻線組立部を構成して、さらに、前記ステータ巻線組立部に前記巻線の巻線端が接続される導電性PINを設けて、この導電性PINの一部が露出されるように前記ステータ巻線組立部をモールド樹脂部で覆い、前記導電性PINの露出した一部にプリント配線板を固定することにより前記ステータ組立部とプリント配線板とを固定し、かつ巻線と前記プリント配線板との電気接続が行なわれるモールドモータであり、前記導電性PINに前記巻線の巻線端が接続される箇所と、この導電性PINの前記モールド樹脂部から露出させる箇所とが異なる箇所であることを特徴とする。   The molded motor of the present invention comprises a stator winding assembly comprising a stator, a winding, and an insulator, and a conductive PIN in which a winding end of the winding is connected to the stator winding assembly The stator winding assembly is covered with a mold resin portion so that a part of the conductive PIN is exposed, and a printed wiring board is fixed to the exposed part of the conductive PIN. A mold motor that fixes an assembly portion and a printed wiring board and electrically connects a winding and the printed wiring board; a location where a winding end of the winding is connected to the conductive PIN; The conductive PIN is different from the portion exposed from the mold resin portion.

なお、本発明は、ステータ、巻線、及びインシュレータを構成要素とするステータ巻線組立部と、このステータ巻線組立部のみを覆ったモールド樹脂部と、前記ステータ巻線組立部の少なくとも一部に固定したプリント配線板とを備えたモールドモータであり、プリント配線板の電子部品のはんだ付け部にモールド成型時のストレスが作用せず高信頼性であること、またプリント配線板を紙フェノール材等安価な材料が使用可能であること、電子部品がモールド樹脂で包まれることがないので、安価なアルミ電解コンデンサをプリント配線板に使用可能であること。プリント配線板をモールド樹脂で一体成型することをしないので、分解しやすくリサイクル性が優れるという作用を有する。   The present invention includes a stator winding assembly having a stator, a winding, and an insulator as constituent elements, a mold resin portion covering only the stator winding assembly, and at least a part of the stator winding assembly. This is a molded motor equipped with a printed wiring board fixed to the board. It is highly reliable without stress during molding at the soldering part of the electronic parts of the printed wiring board, and the printed wiring board is made of paper phenolic material. It is possible to use inexpensive materials such as low-priced materials, and because electronic components are not wrapped with mold resin, inexpensive aluminum electrolytic capacitors can be used for printed wiring boards. Since the printed wiring board is not integrally molded with the mold resin, it has an effect of being easily disassembled and having excellent recyclability.

また、インシュレータの一部が突出してPINとなすステータ組立部を、前記PINが露出するようにモールド樹脂部で覆い、前記PINにプリント基板を固定することにより前記ステータ組立部とプリント配線板とを固定するとよい。   In addition, a stator assembly part, in which a part of the insulator protrudes to become a PIN, is covered with a mold resin part so that the PIN is exposed, and the printed circuit board is fixed to the PIN, thereby fixing the stator assembly part and the printed wiring board. It is good to fix.

また、さらに、インシュレータは熱可塑性樹脂で成型されており、プリント配線板に予め設けた取り付け穴に、PINを挿入し、このPINを熱溶着することで、プリント配線板をステータ組立部に固定すると、プリント配線板の固定を確実かつ簡単に行える。   Furthermore, the insulator is molded from a thermoplastic resin, and when the PIN is inserted into a mounting hole provided in advance in the printed wiring board and this PIN is thermally welded, the printed wiring board is fixed to the stator assembly portion. The printed wiring board can be fixed securely and easily.

また、さらに、更に、ステータ巻線組立部に巻線端を接続した導電性PINを設け、この導電性PINが露出するように前記ステータ巻線組立部をモールド樹脂部で覆い、前記導電性PINにプリント配線板を固定することにより前記ステータ組立部とプリント配線板とを固定し、且つ巻線と前記プリント配線板との電気接続を行うことで、モールド成型されたステータ巻線組立とプリント配線板とを電気的に接続することが極めて容易になる。   Further, a conductive PIN having a winding end connected to the stator winding assembly is provided, and the stator winding assembly is covered with a mold resin portion so that the conductive PIN is exposed. The stator assembly and the printed wiring board are molded by fixing the stator assembly portion and the printed wiring board by fixing the printed wiring board to each other and electrically connecting the winding and the printed wiring board. It becomes extremely easy to electrically connect the plate.

また、さらに、モールド樹脂部に、熱硬化性樹脂を使用することにより、成型時にステータや巻線等に熱的ダメージが少なく信頼性が高い。   Furthermore, by using a thermosetting resin for the mold resin portion, there is little thermal damage to the stator, windings, etc. during molding, and the reliability is high.

また、さらに、モールド樹脂部に、熱可塑性樹脂を使用することにより、熱硬化性樹脂に比べ成型時間が早く、モールドモータの生産性が高くなるだけでなく、加熱すれば流動するため、モールドモータの成型樹脂のリサイクルが容易になる。   Furthermore, by using a thermoplastic resin for the mold resin part, the molding time is faster than the thermosetting resin and the productivity of the mold motor is increased. It becomes easy to recycle the molding resin.

また、プリント基板にモータドライバICを実装したモールドモータに用いることが適している。   Further, it is suitable for use in a molded motor in which a motor driver IC is mounted on a printed board.

以下本発明の実施の形態について、図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1において、モールドモータ1は、モータドライバIC20、電解コンデンサ21をはんだ付け実装したプリント配線板3をモールド成型しないことにより、前記モールドモータ1は、ステータ巻線組立部2、プリント配線板3、ロータ8、ブラケット12の各構成要素に容易に分解可能になる作用を有し、モールド成型されたステータ巻線組立部2に、図1に示すように、前記ロータ8及びプリント配線板3をモールド成型されたステータ巻線組立部2に納めた後、前記モールド成型後のステータ巻線組立部2の上面に取り付ける構成としている。なお、プリント配線板3は上面に限らず、下面に取り付けてもよい。   In FIG. 1, the molded motor 1 does not mold the printed wiring board 3 on which the motor driver IC 20 and the electrolytic capacitor 21 are soldered, so that the molded motor 1 includes the stator winding assembly 2, the printed wiring board 3, As shown in FIG. 1, the rotor 8 and the printed wiring board 3 are molded into the molded stator winding assembly 2 which has an effect that the components of the rotor 8 and the bracket 12 can be easily disassembled. After being placed in the molded stator winding assembly 2, the stator winding assembly 2 is attached to the upper surface of the molded stator winding assembly 2. The printed wiring board 3 is not limited to the upper surface but may be attached to the lower surface.

モールドモータ1を分解する際には、ブラケット12を取り外せば、プリント配線板3、ロータ8を直ちに取り出せる構造のため、分解は極めて容易である。   When the mold motor 1 is disassembled, if the bracket 12 is removed, the printed wiring board 3 and the rotor 8 can be taken out immediately, so that the disassembly is extremely easy.

When the printed wiring board 3 is mounted, the mounting PIN 13 is inserted into the mounting hole 14 provided in advance in the printed wiring board 3, The printed wiring board 3 can be easily fixed to the stator winding assembly 2 by heating the tip end of the protruding mounting PIN 13 and deforming it flatly as shown in FIG. For the insulator 7, a thermoplastic resin is preferably used. Moreover, it is suitable for rationalizing the assembly work by performing the heating work with an automatic machine.

図4は、図1のC部の拡大図であり、ステータ巻線組立2の構成要素であるインシュレータ7に、巻線4が接続された巻線端子PIN15を予め設け、ステータ巻線組立2のモールド成型時には、前記巻線端子PIN15がモールド樹脂4から露出するようにモールド成型を行い、プリント配線板3の取り付けに際しては、前記プリント配線板3に、予め設けた接続穴19に前記巻線端子PIN15を挿入して、接続穴19から突出した巻線端子PIN15の先端部とプリント配線板3の接続穴19の周囲のランド18とはんだ17にてはんだ付けすることにより、プリント配線板3と巻線6の電気的接続が極めて容易に行える。なお、取り付けPINは導電性を有し、取り付けPIN13の上方から押される力がインシュレータ7で保持できるよう、取り付けPIN13をインシュレータ7に乗せた状態で、モールドしている。   FIG. 4 is an enlarged view of a portion C in FIG. 1. The insulator 7, which is a component of the stator winding assembly 2, is previously provided with a winding terminal PIN 15 to which the winding 4 is connected. At the time of molding, molding is performed so that the winding terminal PIN15 is exposed from the mold resin 4. When the printed wiring board 3 is attached, the winding terminal is inserted into the connection hole 19 provided in advance in the printed wiring board 3. By inserting the PIN 15 and soldering with the solder 17 with the tip 18 of the winding terminal PIN 15 protruding from the connection hole 19 and the land 18 around the connection hole 19 of the printed wiring board 3, the printed wiring board 3 and the winding 15 are wound. The electrical connection of the line 6 can be performed very easily. The attachment PIN has conductivity, and is molded with the attachment PIN 13 placed on the insulator 7 so that the force pushed from above the attachment PIN 13 can be held by the insulator 7.

また、はんだ付けに自動はんだ機を用いることで、はんだ付け作業の合理化も可能である。巻線4と巻線端子PIN15との接続は、図中では、巻線の端をPINにかしめることで、接続しているが、はんだ付けで行ってもよい。   Further, by using an automatic soldering machine for soldering, it is possible to rationalize the soldering work. The winding 4 and the winding terminal PIN15 are connected by caulking the end of the winding to the PIN in the drawing, but may be soldered.

なお、以上の説明では、モールド樹脂4の材料について明記しなかったが、プリント配線板をモールド成型しないことにより、プリント配線板にはんだ付け実装されたモータドライバIC等の各種電子部品による温度制約が無く、成型温度が比較的低い熱硬化性樹脂だけでなく、成型温度が高い熱可塑性樹脂でも使用可能である。熱硬化性樹脂、熱可塑性樹脂のいずれでも可能である。   In the above description, the material of the mold resin 4 was not specified, but by not molding the printed wiring board, there are temperature restrictions due to various electronic components such as a motor driver IC soldered and mounted on the printed wiring board. In addition, not only a thermosetting resin having a relatively low molding temperature but also a thermoplastic resin having a high molding temperature can be used. Either a thermosetting resin or a thermoplastic resin is possible.
