Method for attaching a temperature sensor to a weld connection of a hairpin style electric motor stator

Abstract

An electric motor that includes a rotor and a stator, with the rotor being mounted for rotation relative to the stator. The stator includes a plate stack, and a plurality of stator coil wires assembled with the plate stack, with at least some ends of respective ones of the stator coil wires that extend beyond the plate stack being joined together via welded connections in order to complete at least one stator coil circuit. A metal clip is connected to at least one of the welded connections and extends along at least one of the coil wires. The metal clip defines a cavity between itself and the at least one of the coil wires. A temperature sensor is located in the cavity and allows monitoring of the stator coil temperature. A method of assembly is also provided.
