ABSTRACT:
Plastic deformation and nicking of the conductors (30) of the end turns (20) in the stator (10,12,14) of a dynamoelectric machine during the installation of a temperature sensor (26) is avoided by locating the temperature sensor (26) in a gap (22) between the coils defining adjacent end turns (20), thereby providing a machine capable of rapidly responding to excess heat even in a locked rotor situation before detectable levels of smoke, gas, and odors are generated.
