Abstract

See full text

A stator of an electric compressor has a stator core configured by laminating a plurality of electromagnetic steel plates in an axial direction, the electromagnetic steel plates having a substantial ring shape as seen from the axial direction. As seen from the axial direction, a plurality of through-holes are formed through the stator core in the lamination direction of the electromagnetic steel plates, on the same circle centered around the axis line, and as seen from the axial direction, a first arc length or a second arc length longer than the first arc length is set as each arc length between through-holes adjacent in the circumferential direction. The stator is secured to a housing by a bolt inserted through the through-holes, the stator core is varnished at least in areas near the centers in the circumferential direction between through-holes where the second arc length is set.
