Abstract
Description
そこで、本発明は、確実な防水性、防塵性を得ることができるファンモータを提供することを目的とする。
このように構成された本発明においては、包囲体の挿通孔と回転軸との間に包囲体側軸受が設けられているので、包囲体と回転軸との間の隙間が包囲体側軸受で塞がれる。したがって、回転軸を支持する軸受を利用して包囲体が回転子及び固定子を液密に取り囲むことができるので、ファンモータの確実な防水、防塵を実現することができる。
このように構成された本発明においては、回転子が固定子の外側に配置される、所謂アウターロータ構造が採用され、回転子が、包囲体側軸受と固定子側軸受との間で回転軸に固定されているので、回転子が包囲体側軸受と固定子側軸受とによって両持ち構造で支持される。したがって、回転子の回転運動が安定し、ファンモータの安定した回転動作が得られる。
ロータケース18は、円筒状の側壁の上面を円盤状部材で塞いだ有底円筒形状に形成されており、その中央部が、ブシュ24を介して回転軸22に固定されている。ロータケース18の円盤状部材の中央部には、ブシュ24の周りに円形の凹部26が形成されており、凹部26の外周壁26Aは回転軸22の周りに円筒状に、回転軸22に平行に延びている。なお、ロータケース18の凹部26は、必ずしも形成されていなくてもよい。
コアプレート積層体20は、ケイ素鋼板等からなる環状のコアプレートを複数枚積層して形成されており、その上下面には図示しない短絡リングが設けられている。コアプレート積層体20は、固定子6の外側に、固定子6の外面と平行に且つ外面から所定の隙間を有して配置されている。
コアプレート積層体30は、絶縁性プラスチックからなるボビンケース上にケイ素鋼板等からなるコアプレートを複数枚積層して形成されている。コイル32は、コアプレート積層体30の周囲に連続的に巻き回されている。
固定子6の内周は、ブラケット2の円筒状部14の外周に固定されている。ここで、固定子6の内周面は、ロータケース18の凹部26の外周壁26Aよりも半径方向外側に位置する。従って、例えば図1に示されるように固定子6のボビンケース6Aがロータケース18の凹部26の底面よりも上方に突出している場合でも、固定子6がロータケース18に干渉することがない。したがって、ロータケース18内の、凹部26より上方のスペースを有効に利用することができる。
カバー部側軸受44とファン部材10との間には、ブッシュ47が設けられており互いの間の距離が確保されている。
このような、凸部50、鍔部54、凹部52、及び凸部66の構造により、ファン部材10とカバー部8との間の隙間は、迷路状に形成され、当該隙間に液滴や埃が侵入しにくくなっている。また、ファン部材10の凹部64とカバー部8の凸部56によっても、ファン部材10とカバー部8との間の隙間が迷路状に形成され、当該隙間からファン部材10とカバー部8との間に液滴や埃が侵入するのを防止している。また、上面36の中央部には、凹部68が形成されており、この凹部68において、ファン部材10は回転軸22の上端部に固着されている。
カバー部8と回転軸22の間にカバー部側軸受44を設けて、このカバー部側軸受44により回転軸22を回転可能に支持しているので、カバー部8と回転軸22との間に隙間が生じるのを防止することができる。図2に示した従来の構造では、回転軸100は、回転子102を回転軸100に固定するブッシュ116の下方の2箇所において軸受118に支持されている。このような従来の構造では、包囲体106と回転軸100との間に隙間112が生じる。これに対して、本実施形態では、回転子4の外側において、回転軸22を支持するカバー部側軸受44を利用してカバー部8と回転軸22との間の隙間を埋めるようにしたので、カバー部8及びブラケット2で構成された包囲体で回転子6及び固定子4を液密に包囲することができ、カバー部8と回転軸22との間の隙間から液滴や埃等が侵入するのを確実に防止することができる。
また、固定子の絶縁方法としては、前述の実施形態にようにボビンケースを用いるものの他、基体に絶縁樹脂を粉体焼付塗装することにより絶縁性を確保してもよい。
