  • Rotating electrical machine and method of mounting element wire temperature measurement sensors on rotating electrical machine
    Patent number: 9893600
    Abstract: Insulating objects arranged in parallel between adjacent element wire conductors of a plurality of the element wire conductors in a circumferential direction of the rotating electrical machine on each of both sides interposing a dislocating portion of the element wire conductor and linearly extending along the adjacent element wire conductors; a storage space formed between the linear insulating objects arranged in parallel at each of the both sides interposing the dislocating portion; and a temperature detection sensor configured to detect a temperature of the element wire conductors and stored in the storage spaces at each of the both sides interposing the dislocating portion across both sides interposing the dislocating portion are provided, wherein the hardness of the insulating objects is lower than the hardness of the element wire conductors, whereby the types of the rotating electrical machine to which the temperature detection sensor can be applied may be extensively increased.
