A stator for a rotating electric machine includes a stator core, a coil having a coil end, a cooling jacket that is attached to the stator core so as to house the coil end in the cooling jacket and that allows cooling oil to flow therethrough, introduction parts, and discharge parts. The coil end includes first portions, extending parallel to an end surface of the stator core, and pairs of second portions, each pair being connected to both ends of a corresponding one of the first portions, the pairs extending in a direction parallel to an axial direction. The cooling jacket includes an inner circumferential wall and an outer circumferential wall. The introduction parts are provided on the outer circumferential wall, and the discharge parts are provided on the inner circumferential wall.

Stator for rotating electric machine and cooling structure for stator

A coated electric wire for winding that includes an insulation coating including appropriate pores in a resin to suppress erosion due to partial discharge is provided. The present disclosure relates to a coated electric wire for winding that includes a conductor and an insulation coating that coats a periphery of the conductor, wherein the insulation coating includes a constant volume of pores having an average diameter equal to or more than a pore diameter (A) obtained by a specific measuring method.
