Stator, stator manufacturing method, rotary electric machine, and rotary electric machine manufacturing method

Abstract

This invention discloses a stator capable of improving heat dissipation performance. One embodiment of the solution includes a stator core and a coil block. The stator core has an annular yoke centered on a central axis and a plurality of teeth protruding axially or radially from one face of the yoke and arranged circumferentially. The coil block is located within a plurality of slots formed by circumferentially arranged adjacent teeth among the plurality of teeth. The coil block comprises a coil formed by winding a conductor into a loop and a resin layer integrally molded onto the coil. The resin layer is disposed at least on the inner periphery of the coil.
