STATOR FOR ROTARY ELECTRIC MACHINE

摘要

A cooling oil is supplied from a cooling pipe to an outer peripheral surface of a mold resin, and a thermistor for measuring a temperature of a coil is provided at one end portion of the mold resin in an axial direction of a stator. A bulge portion for restraining the cooling oil from being supplied to the thermistor is provided bulging outward in the axial direction of the stator in such a manner as to surround at least part of a periphery of the thermistor, at one end portion of the mold resin in the axial direction of the stator.

1. A stator for a rotary electric machine, the stator comprising:
a stator core; a coil that is wound around the stator core; a mold portion that includes a coil end portion, the coil end portion projecting outward from the stator core of the coil in an axial direction of the stator, a bulge portion being provided at an end portion of the mold portion in the axial direction of the stator, the mold portion being configured to mold the coil end portion, and a liquid cooling medium being supplied from a cooling medium supply member to an outer peripheral surface of the mold portion; and a temperature sensor that is provided at the end portion of the mold portion in the axial direction of the stator, the temperature sensor being configured to measure a temperature of the coil, wherein the bulge portion is provided bulging outward in the axial direction of the stator to surround at least part of a periphery of the temperature sensor, the bulge portion is configured to restrain the liquid cooling medium from being supplied to the temperature sensor, and the bulge portion is molded integrally with the mold portion.
