用于旋转式电机的定子及使用该定子的旋转式电机
Abstract:
一种用于形成定子绕组(20)的线材(30)包括设置在定子芯(12)的槽(14和15)内的槽收容部(40)，以及弯曲部(42)，弯曲部(42)从槽(14和15)突出到定子芯(12)的外部并且连接设置于沿圆周不同的槽(14和15)内的槽收容部(40)。弯曲部(42)单独地形成在定子芯(12)的轴向两侧上。没有扭转的曲柄部(44)形成在弯曲部(42)的基本上中心部分。台阶部(46)形成在弯曲部(42)的突出部，该突出部从槽(14和15)突出到定子芯(12)的外部。此外，线材(30)的台阶部(42)各自具有在形成于基本上中心部分的曲柄部(44)和台阶部(46)之间的两个台阶部(48)，台阶部(46)形成在弯曲部(42)的突出部处。
Abstract(English):

A wiring material (30) for forming a stator wire (20) includes slot housing portions (40) to be disposed in the slots (14 and 15) of a stator core (12), and turn portions (42) protruding from the slots (14 and 15) to the outside of the stator core (12) and connecting the slot housing portions (40) disposed in the circumferentially different slots (14 and 15). The turn portions (42) are formed individually on the two axial sides of the stator core (12). A crank portion (44) followed by no torsion is formed at the substantially central portion of the turn portions (42). Step portions (46) are formed at the protruding portions of the turn portions (42) protruding from the slots (14 and 15) to the outside of the stator core (12). Moreover, the step portions (42) of the wiring material (30) individually have two step portions (48) formed between the crank portion (44) of the substantially central portion and the step portions (46) formed at the protruding portions of the turn portions (42).
