Manufacturing method of rotary electric motor and rotary electric motor

Abstract

In an exemplary embodiment of a method for manufacturing a rotary electric machine, the rotary electric machine includes a housing, a rotor capable of rotating around a central axis, and a stator disposed opposite to the rotor, all located inside the housing. A thermistor is located inside a through-hole penetrating a side wall portion of the housing. The method for manufacturing the rotary electric machine includes a dummy pin placement process, a resin layer placement process, a dummy pin removal process, and a thermistor placement process. The dummy pin placement process involves placing a dummy pin in the through-hole to seal it. The resin layer placement process involves placing a resin layer between the side wall portion of the housing and the coil of the stator. The dummy pin removal process involves removing the dummy pin from the through-hole. The thermistor placement process involves placing a thermistor for detecting the temperature of the coil in the through-hole.
