摘要:
A cooling structure for a stator includes: a stator core; a stator coil that is wound on the stator core and includes a coil end formed on an end surface of the stator core in an axial direction of the stator core; a ring member provided on an outer periphery of the stator core; a case that houses the ring member and the stator core on which the stator coil is wound. In the cooling structure, a cooling medium is supplied between an outer peripheral surface of the ring member and an inner peripheral surface of the case, and the ring member includes at least one opening through which the cooling medium is supplied to the coil end from radially outside of the coil end.
