- コイルが巻線されたステータと当該ステータに対向配置されるマグネットを有するロータと有し、当該コイルへの通電と通電の停止により前記ステータの磁極を変化させて前記ロータを回転駆動するステッピングモータと、
前記ロータの回転軸により回転駆動されるインペラと、
前記インペラを前記回転軸に対して相対的に回転可能に連結する連結手段とを備え、
前記連結手段は、一端が前記回転軸方向に延在して前記インペラの取り付け孔に連結され、他端が前記回転軸方向に延在して前記回転軸に軸着されたホルダの取り付け孔に固定され、前記回転軸まわりに巻回されたコイルバネであって、モータ起動時には前記回転軸が前記インペラに対して空転しつつ当該インペラの慣性力を吸収し、前記回転軸の回転数が上昇するにつれて吸収した力を放出して前記インペラを前記回転軸に対して追従して回転させることを特徴とするファンモータ。 - 前記ステータは、前記マグネットと同心円状に巻き回された前記コイルと、前記コイルを取り囲むように保持し、前記マグネットと前記コイルとの間に介在する磁極部とを有し、
前記磁極部は、前記コイルへの通電と通電の停止時に、前記マグネットとの間隙を不均一にする凹部が設けられていることを特徴とする請求項1に記載のファンモータ。 - 前記コイルへの通電を制御するためのCMOSトランジスタを有する駆動回路を更に備えることを特徴とする請求項1又は2に記載のファンモータ。
- 前記駆動回路は、時計用ICと同等であることを特徴とする請求項3に記載のファンモータ。
- 前記駆動回路は、起動時に出力するパルス周波数が定常時よりも低く設定されていることを特徴とする請求項3又は4に記載のファンモータ。
- 前記ファンモータの外装の一部に太陽電池が設けられ、前記駆動回路は当該太陽電池を電源として駆動されることを特徴とする請求項3乃至5のいずれか1項に記載のファンモータ。
