As the fan 6 rotates, the fan 6 also rotates and can blow air.
（発明の効果）
不発明は叙上のようにリング状のマクネット及びヨーク
よりｍ成されるロータ部の内側にファンを取付けて構成
されているので、
（ａ）ファンの外径があまり大きくならず、従ってファ
ン回転数が高くなっても騒音が犬きくならない。(Effects of the invention) As mentioned above, the invention is constructed by attaching the fan to the inside of the rotor section, which is composed of a ring-shaped mucknet and a yoke. (a) The outer diameter of the fan is too large. Therefore, even if the fan rotation speed increases, the noise does not become too loud.
（ｂ）ファン、モータのロータ外径が小きくアンバラン
スが小さい。(b) The outer diameter of the rotor of the fan and motor is small and the unbalance is small.
（ｅ）ファンの風洞部を別途に設ける必要がないので、
部品点数が少なくて良い。(e) There is no need to separately provide a wind tunnel section for the fan;
It is good to have fewer parts.
（ｄ） ＩＪング状のマグネットがステータに対向する
表面積が大きいので、マグネットの磁束密度を大きくと
ることができる。(d) Since the IJ ring-shaped magnet has a large surface area facing the stator, the magnetic flux density of the magnet can be increased.
（ｅ）軸受、ステータコイルの冷却がやり易いのでモー
タの寿命が長い。(e) The bearing and stator coil can be easily cooled, so the motor has a long life.
