The present invention relates to a new improvement for individually guiding, preventing contact between phases and preventing floating lines between projecting magnetic poles.
従来のレゾルバの渡り線構造としては、例えば、特許文献1に開示されている構造を図4及び図5に示すことができる。
すなわち、図4及び図5において符号1で示されるものは輪状ステータであり、この輪状ステータ1の内面には、所定角度間隔で内方へ向けて突出する複数の突出磁極2が一体に形成されている。
As a crossover structure of a conventional resolver, for example, the structure disclosed in Patent Document 1 can be shown in FIGS.
That is, what is denoted by reference numeral 1 in FIGS. 4 and 5 is a ring-shaped stator, and a plurality of projecting magnetic poles 2 projecting inward at predetermined angular intervals are integrally formed on the inner surface of the ring-shaped stator 1. ing.

従来のレゾルバの渡り線構造は、以上のように構成されていたため、次のような課題が存在していた。
すなわち、突出壁部の外面が平面で形成されているため、各相の渡り線は分離されずに上下方向に沿って積み重ね状となり、互いに接触するため、被膜が損傷してショートすることもあった。
また、各相の渡り線をワニス剤で固定しなければならず、大量生産時の生産性向上へのネックとなっていた。
Since the crossover structure of the conventional resolver is configured as described above, the following problems exist.
That is, since the outer surface of the protruding wall portion is formed as a flat surface, the connecting wires of each phase are not separated but are stacked in the vertical direction and contact each other, so that the coating may be damaged and short-circuited. It was.
Moreover, the crossover of each phase had to be fixed with a varnish agent, which was a bottleneck in improving productivity during mass production.
本発明によるレゾルバの渡り線傷付及び浮き防止構造は、所定角度間隔で内方へ向けて突出する複数の突出磁極を有する輪状ステータと、前記輪状ステータの両面に一体又は別体にて設けられた輪状絶縁カバーと、前記輪状絶縁カバーに突出して形成され前記各突出磁極に対応して位置する耳部と、前記輪状絶縁カバーに形成され軸方向に沿って突出する突出壁部と、前記各突出磁極に前記耳部を介して巻回されたステータ巻線と、を備え、前記各突出磁極に巻回された各ステータ巻線の渡り線は、前記突出壁部を介して案内されるように構成したレゾルバの渡り線傷付防止構造において、前記突出壁部は前記各突出磁極間のスロットに対応して形成され、前記突出壁部の外面には、複数段からなる段部が形成され、前記各段部には互いに異なる相の前記ステータ巻線の渡り線が位置し、ワニス剤による固定が行われていない構成であり、また、前記突出磁極の円周方向に沿う幅は、前記スロットのスロット幅と一致している構成である。 According to the present invention, the crossover damage and floating prevention structure of a resolver is provided integrally or separately on a ring-shaped stator having a plurality of projecting magnetic poles projecting inward at predetermined angular intervals, and on both surfaces of the ring-shaped stator. A ring-shaped insulating cover; an ear portion protruding from the ring-shaped insulating cover and positioned corresponding to each protruding magnetic pole; a protruding wall portion formed in the ring-shaped insulating cover and protruding along the axial direction; A stator winding wound around the projecting magnetic pole through the ear, and the connecting wire of each stator winding wound around the projecting magnetic pole is guided through the projecting wall. In the resolver crossover damage prevention structure configured as described above, the protruding wall portion is formed corresponding to the slot between the protruding magnetic poles, and a plurality of stepped portions are formed on the outer surface of the protruding wall portion. The step portions are different from each other. The connecting wire of the stator winding of the phase is located and is not fixed with a varnish agent, and the width along the circumferential direction of the protruding magnetic pole matches the slot width of the slot. It is the composition which is.
本発明によるレゾルバの渡り線傷付及び浮き防止構造は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、所定角度間隔で内方へ向けて突出する複数の突出磁極を有する輪状ステータと、前記輪状ステータの両面に一体又は別体にて設けられた輪状絶縁カバーと、前記輪状絶縁カバーに突出して形成され前記各突出磁極に対応して位置する耳部と、前記輪状絶縁カバーに形成され軸方向に沿って突出する突出壁部と、前記各突出磁極に前記耳部を介して巻回されたステータ巻線と、を備え、前記各突出磁極に巻回された各ステータ巻線の渡り線は、前記突出壁部を介して案内されるように構成したレゾルバの渡り線傷付及び浮き防止構造において、前記突出壁部は前記各突出磁極間のスロットに対応して形成され、前記突出壁部の外面には、複数段からなる段部が形成され、前記各段部には互いに異なる相の前記ステータ巻線の渡り線が位置し、ワニス剤による固定が行われていないことにより、各相の渡り線相互の接触を防止し、ワニス剤を用いることなく損傷防止が可能で、浮き線を防止し、振動による断線を防止し、生産性の向上を得ることができる。
また、前記突出磁極の円周方向に沿う幅は、前記スロットのスロット幅と一致していることにより、渡り線の保持が完全となり、信頼性の向上となる。

That is, a ring-shaped stator having a plurality of projecting magnetic poles projecting inward at predetermined angular intervals, a ring-shaped insulating cover provided integrally or separately on both surfaces of the ring-shaped stator, and projecting from the ring-shaped insulating cover Ears that are formed and positioned corresponding to the projecting magnetic poles, projecting wall parts that are formed on the annular insulating cover and project along the axial direction, and are wound around the projecting magnetic poles via the ears A stator winding, and a crossover of each stator winding wound around each protruding magnetic pole is configured to be guided through the protruding wall portion. The projecting wall portion is formed corresponding to the slot between the projecting magnetic poles, and a plurality of step portions are formed on the outer surface of the projecting wall portion. The connecting wire of the stator winding The varnish agent is not fixed and prevents the crossover of each phase of the crossover wires, preventing damage without using the varnish agent, preventing floating lines, and preventing disconnection due to vibration. In addition, productivity can be improved.
Further, since the width of the protruding magnetic pole along the circumferential direction coincides with the slot width of the slot, the crossover is completely retained and the reliability is improved.
