PROBLEM TO BE SOLVED: To provide an improved electric motor low in acoustic noise and cost, and a stator.SOLUTION: The stator includes a stator core, three-phase windings wound around the stator core and a neutral point terminal; each three-phase winding includes a phase connection end and a neutral point connection end; the neutral point connection end of each three-phase winding is fixed to the neutral point terminal and is electrically connected thereto; and the neutral point connection ends of the three-phase windings are electrically connected together in the outside of a circuit board. The circuit board does not need to provide an excessive space or a wiring layer for combining the neutral point connection ends of the three phase windings.SELECTED DRAWING: Figure 5 【課題】騒音が低くしかもコストが安い、改善された電気モータ及びステータを提供する。【解決手段】ステータは、ステータコアと、ステータコア上に巻き付けた三相巻線とを含む。ステータは中性点端子を与え、各々の三相巻線は、相接続端及び中性点接続端を備え、各々の三相巻線の中性点接続端は、中性点端子に固定されかつこれに電気的に接続される。三相巻線の中性点接続端は、回路基板の外部で電気的に一緒に接続される。回路基板は、三相巻線の中性点接続端を組み合わせるための余分な空間又は配線層を設ける必要がない。【選択図】図５
