Abstract
Description
<送風機の構成>
図1は、実施の形態1の送風機5を示す縦断面図である。送風機5は、シャフト18を有するモータ3と、モータ3を収容するモータハウジング4と、モータ3のシャフト18に取り付けられた動翼6とを備える。
図2は、モータ3を示す横断面図である。モータ3は、回転可能なロータ1と、ロータ1を囲むように設けられた環状のステータ2とを有する。モータ3は、ロータ1に永久磁石16を埋め込んだ永久磁石埋込型モータである。ステータ2とロータ1との間には、例えば0.4mmのエアギャップGが設けられている。
ステータ2は、ステータコア20と、ステータコア20に巻き付けられたコイル25とを有する。ステータコア20は、複数枚の電磁鋼板を軸方向に積層し、カシメ等により固定したものである。電磁鋼板の板厚は、例えば0.2mm~0.5mmである。
図2に示すように、ロータ1は、シャフト18と、シャフト18に固定されたロータコア10と、ロータコア10に埋め込まれた複数の永久磁石16とを有する。
次に、実施の形態1の作用について説明する。図4は、磁束密度の実測によって求めた、ロータ1の外周における磁束密度分布を示すグラフである。縦軸は磁束密度[mT]であり、横軸は周方向位置、すなわち軸線C1を中心とする角度[度]である。
以上説明したように、この実施の形態1の送風機5では、ステータ2を径方向外側から囲むフレーム41と、シャフト18に取り付けられた動翼6とが、いずれも非磁性材料で形成されている。そのため、送風機5の外部への磁束漏れを、フレーム41および動翼6によって抑制することができる。
図14は、実施の形態2の送風機5Aを示す断面図である。上述した実施の形態1では、モータハウジング4のフレーム41が、ベアリング32を保持する側壁部41bを有していた。これに対し、実施の形態2では、フレーム41とは別部材のベアリング支持部43が、ベアリング32を保持するように構成されている。
図15は、実施の形態3のロータ1Aを示す断面図である。上述した実施の形態1では、ロータコア10の内周にシャフト18が固定されていた。これに対し、この実施の形態3では、ロータコア10の内周10bとシャフト18との間に、樹脂部17が形成されている。
次に、上述した各実施の形態のモータを適用した空気調和装置について説明する。図16は、実施の形態1のモータ3を適用した空気調和装置200の構成を示す図である。空気調和装置200は、室外機100と、室内機201と、これらを接続する冷媒配管206とを備える。
