Description
本発明のある態様は、ブラシレスモータを備える電動工具であって、
前記ブラシレスモータは、Δ結線された複数の相を有し、かつ各相に並列接続された複数のステータコイルを含み、
前記ブラシレスモータの軸方向に関する前記ブラシレスモータのステータコアの長さをＬ（ｍｍ）、前記ブラシレスモータの無負荷回転数をＲ（／ｍｉｎ）、前記ブラシレスモータの駆動電圧の実効値をＶ（Ｖ）としたとき、次の（１）及び（２）の少なくとも一方を満足する。
（１）Ｌmin＜Ｌ、かつ、Ｌmin＝（−０．０００８×Ｒ＋４６．７）×Ｖ÷２０
（２）Ｌ＜Ｌmax、かつ、Ｌmax＝（−０．００１７×Ｒ＋９３．４）×Ｖ÷２０
An aspect of the present invention is an electric tool including a brushless motor,
The brushless motor includes a plurality of stator coils having a plurality of phases Δ-connected and connected in parallel to each phase;
The length of the stator core of the brushless motor in the axial direction of the brushless motor is L (mm), the no-load rotation speed of the brushless motor is R (/ min), and the effective value of the driving voltage of the brushless motor is V (V). When satisfied, at least one of the following (1) and (2) is satisfied.
(1) Lmin <L and Lmin = (− 0.0008 × R + 46.7) × V ÷ 20
(2) L <Lmax and Lmax = (− 0.0017 × R + 93.4) × V ÷ 20
前記（１）及び（２）の両方を満足してもよい。 Both (1) and (2) may be satisfied .
