STATOR AND DYNAMO-ELECTRIC MOTOR

To appropriately bridge a crossover regardless of a kind of a winding machine.SOLUTION: A stator comprises: a stator core having twelve teeth parts; and an insulator having a crossover holding part holding crossovers in three phases. The crossover in each phase includes: a first crossover; a second crossover; and a third crossover bridged between two teeth parts that lie across fourth teeth parts of the other two phases. The crossover holding part includes: a pair of first notch grooves in which the first crossover is bridged; a pair of second notch grooves in which the second crossover is bridged; and a pair of third notch grooves in which the third crossover is bridged. Both of the pair of first notch grooves are deep grooves, and both of the pair of second notch grooves are shallow grooves. The pair of third notch grooves in which the third crossover of the two phases is bridged includes a deep groove and a shallow groove, and both of the pair of third notch grooves in which the third crossover of the other one phase is bridged are deep grooves.SELECTED DRAWING: Figure 8 【課題】巻線機の種類によらずに渡り線を適正に架け渡すこと。【解決手段】ステータは、１２個のティース部を有するステータコアと、３つの相の渡り線を保持する渡り線保持部を有するインシュレータとを備える。各相の渡り線は、第１の渡り線と、第２の渡り線と、他の２つの相の４つのティース部を挟む２つのティース部の間に架け渡される第３の渡り線とを含む。渡り線保持部は、第１の渡り線が架け渡される一対の第１の切欠き溝と、第２の渡り線が架け渡される一対の第２の切欠き溝と、第３の渡り線が架け渡される一対の第３の切欠き溝とを含む。一対の第１の切欠き溝はいずれも深溝であり、一対の第２の切欠き溝はいずれも浅溝であり、２つの相の第３の渡り線が架け渡される一対の第３の切欠き溝は深溝と浅溝を含み、他の１つの相の第３の渡り線が架け渡される一対の第３の切欠き溝はいずれも深溝である。【選択図】図８
