Abstract
Description
図1は、実施の形態1に係るモータを示す側面図である。
図1に示すように、本実施の形態におけるモータは、本体外殻1と、この本体外殻1に内包されたステータ20およびロータ30と、ロータ30に連結されたシャフト40と、本体外殻1の端部を閉塞するブラケット2とを備えている。また、本体外殻1の側面には、ステータ20に接続されるリード線120の口出し部121が設けられている。
図3は、実施の形態1に係るモータ本体を示す斜視図である。
図2、図3に示すように、本体外殻1は、軸芯部を囲んで環状に形成され、内側にはステータ20が固定されている。このステータ20の内周側には、軸受を介して回転自在に支持されたロータ30(図示せず)が配置される。
ここでは、本体外殻1が、ステータ20を樹脂によりモールド成型したモールドステータの外殻により形成されている場合を例に説明する。
なお、樹脂の種類は特に指定をするものでなく、例えば、不飽和ポリエステル、飽和ポリエステル、発泡性樹脂でもよい。また、本実施の形態では、樹脂による一体成型を例に説明するが、成型方法は樹脂での成型に限らず、アルミダイキャストや、金属の削り品でもよい。
第1本体脚部101は、ネジ等の固定部材を介して、本体外殻1とブラケット2とを締結するものである。第2本体脚部102は、ネジ等の固定部材を介して、本体外殻1とブラケット2とを締結すると共に、モータと支持部材320(後述)とを固定するものである。固定状態の詳細は後述する。
この第1本体脚部101及び第2本体脚部102は、平面視において、リード線120の口出し部121と重ならない位置に形成されている。例えば図2に示すように、リード線120の口出し部121の近傍の第1本体脚部101と、第2本体脚部102との間の間隔を他の部分の間隔より狭くしている。
本実施の形態では、リード線120の口出し部121を側面に設けることで、樹脂により成型する本体外殻1の成型時の生産性を向上できると共に、モータ底面(ブラケット2側)の防水性を向上できる。そして、第1本体脚部101及び第2本体脚部102は、平面視において、リード線120の口出し部121と重ならない位置に形成されているので、リード線120と第1本体脚部101及び第2本体脚部102とが干渉せず、取り付けの作業性を向上することができる。
図5は、実施の形態1に係るモータのブラケットを示す斜視図である。
図4、図5に示すように、ブラケット2は、本体外殻1と略同径の円盤状に形成されている。このブラケット2は、ステータ20の端面に配置されて中心部にロータ30を支持する軸受が装着されて周縁部側が本体外殻1に固定される。
ブラケット2の周縁部には、外側に突出して、第1ブラケット脚部201と第2ブラケット脚部202とが、上記第1本体脚部101及び第2本体脚部102に対応する位置にそれぞれ複数形成されている。
第1ブラケット脚部201は、ネジ等の固定部材を介して、本体外殻1とブラケット2とを締結するものである。第2ブラケット脚部202は、ネジ等の固定部材を介して、本体外殻1とブラケット2とを締結すると共に、モータと支持部材320(後述)とを固定するものである。固定状態の詳細は後述する。
図6に示すように、室外機300は、箱状に形成された筐体310と、筐体310の側面の開口により形成された吸込口308と、吸込口308に沿うように筐体310内に配置された熱交換器(図示せず)と、筐体310の天面の開口により形成された吹出口309と、この吹出口309を覆うように通風可能に設けられたファンガード311と、このファンガード311の内部に設置され上記モータにより駆動されるファン312とを備えている。
図7において、支持部材320は、例えば2本のレールにより構成され、モータは、底面側(ブラケット2側)が支持部材320と接し、シャフト40が上方に向くように載置される。モータのシャフト40には、ファン312が取り付けられ、モータのロータが回転することにより駆動される。
図8に示すように、支持部材320は、2本のレールにより構成されている。そして、本体外殻1の軸芯部を中心にして90°間隔で4つ設けられ第2本体脚部102及び第2ブラケット脚部202が、1本のレール上にそれぞれ2つ締結されている。このような構成により、モータの下方から上方に向かう風の抵抗を軽減することができる。
図9に示すように、支持部材320の上に、ブラケット2の第2ブラケット脚部202と、本体外殻1の第2本体脚部102とが配置され、これら3つがネジ400により締結され、モータと支持部材320とが固定される。
このため、モータを支持部材320に固定すると共に、本体外殻1とブラケット2とを、モータの自重及び固定部材により密着締結し、防水性能を向上することができる。
図10に示すように、本体外殻1の第1本体脚部101には、ネジ孔101aが形成されている。また、ブラケット2の第1ブラケット脚部201には、ネジ孔201aが形成されている。そして、ネジ孔101a、201aに、ネジ400が挿入されることで、本体外殻1とブラケット2とが締結される。
なお、ここでは固定部材として、ネジ400を用いた場合を説明したが、固定部材としてはネジに限定されるものでなく、例えば、リベットによる固定や、金属棒を差し込み固定してもよい。
図11に示すように、本体外殻1の第2本体脚部102には、ネジ孔102aが形成されている。また、ブラケット2の第2ブラケット脚部202には、ネジ孔202aが形成されている。また、支持部材320には、ネジ孔320aが形成されている。そして、ネジ孔102a、202a、320aに、ネジ400が挿入されることで、本体外殻1とブラケット2と支持部材320が締結される。
なお、ここでは固定部材として、ネジ400を用いた場合を説明したが、固定部材としてはネジに限定されるものでなく、例えば、リベットによる固定や、金属棒を差し込み固定してもよい。
なお一般的なモータであれば、せん断力は10Nから20N程度となっている。このせん断力であれば、ネジのせん断応力からφ4程度で耐えうる。よって汎用性を持たせるため、ネジ孔102a、202a、320aの穴径はφ8とするのが望ましい。
このように、本体外殻1の脚部の寸法を小さくすることで、本体外殻1の材料費を軽減することができる。また、本体外殻1を樹脂により成型する場合には、金型成型時の不備を軽減することができる。
このため、モータの本体外殻1とブラケット2との隙間から毛細管現象等によって水などが浸入することを防止することができる。また、モータを支持部材320に固定することができる。
また、モータの自重によりブラケット2を支持部材320に挟む状態で、第2本体脚部102と第2ブラケット脚部202と支持部材320とが締結されるので、モータの防水性を向上することができる。
また、本体外殻1とブラケット2とを締結すると共に、モータを支持部材320に固定するので、モータと支持部材320とを固定するための構成が簡易化することができる。
このため、モータと支持部材320とを固定するための構成を別途設ける必要が無くなり、簡易な構成によりモータを支持部材320に固定することができる。また、本体外殻1を樹脂により成型する場合であっても、本体外殻1とブラケット2との間の密着性を向上することができ、モータの防水性を向上することができる。
このため、空気調和機等の筐体内に配置する場合、ファン312による風がモータ周囲に流通する際の風路抵抗を小さくすることができる。
