Abstract
Description
以下に図1~図4を用いて本発明の1実施形態であるリニアモータ100について説明する。なお、図1、図2では、後述のヨーク23(図3示)を省略して表している。また、本実施形態のリニアモータ100は、電子部品実装装置の装着ヘッドを移動させる移動装置に用いられるが、電子部品実装装置の構成は、上記した特許文献1や特開2010-172070号公報に開示され周知であるので、説明を割愛する。
以下に図5を用いて、比較例として従来のリニアモータについて、本実施形態のリニアモータ100と異なる点について説明する。なお、従来のリニアモータにおいて、本実施形態のリニアモータ100と同じ構造の部分については、同じ番号を付して、その説明を省略する。
以上詳細に説明したように、本実施形態のリニアモータ100によれば、図3や図4に示すように、隣接するコイル22の間に、コイル22の側周面に沿うように熱伝達部材26を設けた。これにより、図4に示すように、コイル22の側周面と熱伝達部材26が曲面で無く平面で接触するので、コイル22の側周面と熱伝達部材26が確実に接触する。このため、コイル22で発生した熱が確実に熱伝達部材26に伝熱し、コイル22で発生した熱を、熱伝達部材26を介して確実に放熱させることができ、リニアモータ100の冷却性能を向上させることが可能となる。また、コイル22の側周面の両側に熱伝達部材26が接触するので、従来と比べて、コイル22で発生した熱をより多く熱伝達部材26に伝熱させることができる。また、可動子20の製造時において、集熱部26aを隣接するコイル22の間に配設後に、両端のコイル22が互いに近接する方向に(圧縮方向に)、両端のコイル22に荷重をかけることにより、コイル22を集熱部26aに確実に密着させることができ、コイル22で発生した熱を確実に熱伝達部材26に伝熱させることができる。
