Zusammenfassung:	To provide a power tool with excellent workability.SOLUTION: In a power tool 1, a motor 3 is a brushless motor and has two stator coils in each of U-phase, V-phase, and W-phase. The power tool is switched to a first state in which the two stator coils in each phase are connected in series by interlocking with forward and backward movement of a winding switching lever 20 which is exposed to the outside of a housing 2 and is operable by an operator and the phases are Y-connected and a second state in which the two stator coils in each phase are connected in parallel and the phases are delta-connected.SELECTED DRAWING: Figure 1 【課題】作業性の良好な動力工具を提供する。【解決手段】動力工具１において、モータ３は、ブラシレスモータであって、Ｕ相、Ｖ相及びＷ相の各々において２つの固定子コイルを有する。ハウジング２の外部に露出し作業者が操作可能な巻線切替レバー２０の前後動に連動して、各相の２つの固定子コイルが直列接続されると共に相同士がＹ結線された第１の状態と、各相の２つの固定子コイルが並列接続されると共に相同士がデルタ結線された第２の状態と、が切り替わる。【選択図】図１
