従来、用いられていたこの種の回転センサの信号線引出し構造としては、例えば、巻線が施されているスロット内で巻線の端線とリード線とを直接結線してリード線を取付ける方法、又は、基板を介して巻線の端線とリード線とを製造してリード線を取付ける方法とがある。
そのうち、前者の従来例としては、特許文献１の構成を図６に挙げることができる。 Conventionally, as a signal line drawing structure of this type of rotation sensor used, for example, a method of attaching a lead wire by directly connecting an end wire of a winding and a lead wire in a slot in which the winding is applied.
