Description
この発明に係る圧縮機用電動機の固定子は、複数の固定子鉄心が円環状に連結されて構成され、複数の固定子鉄心のそれぞれの軸方向の端面に絶縁部材が配置された圧縮機用電動機の固定子であって、複数の固定子鉄心に絶縁部材を介して巻回された複数のコイルと、絶縁部材における固定子鉄心とは反対側の端面に設けられた矩形状の凹部を有する中性点絶縁保持機構と、両端が開口した断面矩形状の外部接続端子内に複数のコイルから引き出された複数の端末線が挿入された状態で、外部接続端子の側面が押圧されてカシメられたカシメ部を有する中性点とを備え、中性点が、中性点絶縁保持機構の凹部内に挿入されて圧入保持されており、その状態において中性点の挿入方向とは反対側の端面が凹部の開口面よりも引っ込んだ位置にあるものである。 The stator of the electric motor for a compressor according to the present invention is configured by connecting a plurality of stator cores in an annular shape, and an insulating member is arranged on each axial end face of the plurality of stator cores for a compressor. It is a stator of an electric motor and has a plurality of coils wound around a plurality of stator cores via an insulating member and a rectangular recess provided on an end face of the insulating member opposite to the stator core. The side surface of the external connection terminal is pressed and crimped with the neutral point insulation holding mechanism and multiple terminal wires drawn from multiple coils inserted into the external connection terminal with a rectangular cross section with both ends open. It has a neutral point with a crimped portion, and the neutral point is inserted into the recess of the neutral point insulation holding mechanism and press-fitted and held, and in that state, it is on the side opposite to the insertion direction of the neutral point. The end face is in a position recessed from the opening surface of the recess.
