Zusammenfassung:PROBLEM TO BE SOLVED: To provide a stator capable of reducing the height of a coil end thereby miniaturizing the size.SOLUTION: A stator 11 comprises: a stator core 12 in which a rotor is housed in an inner part, and that includes a plurality of teeth and a plurality of slots alternately formed in a rotation direction; and a three-phase AC circuit that includes a coil wound in a wave wind state to the plurality of slots at a predetermined pitch. The three-phase AC circuit is constructed by a double star connection that is formed by parallelly connecting a pair of coils U1 and U2 wound to the plurality of slots by a plurality of turns. In the circuit, an inlet port to which an electric supply part of one coil U1 is connected and an inlet port to which the electric supply part of the other coil U2 is connected are arranged in a different layer in a radial direction of the pair of coils U1 and U2. When the number of slot of the stator core 12 is Ns, and a pole number of the rotor is Np, the inlet port of one coil U1 and the inlet port of the other coil U2 are arranged at a position separated by 2Ns/Np+1 slot.SELECTED DRAWING: Figure 2 【課題】コイルエンド高さを低くすることができ、小型化を図ることのできるステータを提供すること。【解決手段】ステータ11は、内部にロータが収容され、回転方向に交互に形成された複数のティースおよび複数のスロットを有するステータコア12と、複数のスロットに所定のピッチで波巻き状に巻回されたコイルを有する三相交流回路とを備え、三相交流回路は、複数のスロットに複数ターン巻回された一対のコイルU1、U2を、並列接続したダブルスター結線して構成され、一方のコイルU1の給電部が接続される入口と、他方のコイルU2の給電部が接続される入口とが、一対のコイルU1、U2の径方向で異なるレイヤーに配置され、ステータコア12のスロット数をNs、ロータの極数をNpとしたときに、一方のコイルU1の入口と、他方のコイルU2の入口とは、2Ns/Np+1スロット離れた位置に配置される。【選択図】図2
