Description

本発明は、ステータ巻線構造に関し、特に、各磁極に巻回された各ステータ巻線間を、板状の相間絶縁部材で絶縁すると共に、この相間絶縁部材を各絶縁キャップで係合させて固定するための新規な改良に関する。   The present invention relates to a stator winding structure, and in particular, each stator winding wound around each magnetic pole is insulated with a plate-shaped interphase insulating member, and the interphase insulating member is engaged with each insulating cap. It relates to a new improvement for fixing.

従来、用いられていたこの種のモータ等のステータ巻線構造としては、例えば、特許文献１の構成があるが、実際には、ステータ巻線と磁極との間には、樹脂の絶縁キャップと薄膜状樹脂の絶縁シートを配して絶縁構造を形成し、スロット内の絶縁としては、Ｖ字状をなす薄膜状樹脂の絶縁シートを配設していた。   As a conventional stator winding structure for this type of motor, for example, there is a configuration of Patent Document 1, but in practice, a resin insulation cap and a stator winding are provided between the stator winding and the magnetic pole. A thin-film resin insulation sheet is arranged to form an insulation structure, and a V-shaped thin-film resin insulation sheet is provided as insulation in the slot.

また、このＶ字型の薄膜状樹脂は柔らかく作業性が悪く、歩留まりの向上が困難であった。 Since the conventional stator winding structure is configured as described above, the following problems exist.
That is, the conventional insulating structure using the V-shaped thin film resin has a variation in the insulating state, and the reliability for the insulation is not sufficient.
Further, this V-shaped thin film resin was soft and poor in workability, and it was difficult to improve the yield.
