Temperature sensor pocket for dynamoelectric machine winding

摘要

Difficulties in sensing the temperature of end turns in dynamoelectric machines are avoided through the use of an envelope containing a temperature sensor disposed between abutting sets of end turns in such machine. The envelope has two insulating plies formed of insulating material sandwiching a ply formed of metal having excellent thermal conductivity. The latter is bonded to the former such that an exposed edge of the insulating plies exists by which the envelope may be closed to totally encapsulate the metal ply.
