<P>PROBLEM TO BE SOLVED: To more suitably measure temperature of a rotary electric machine. <P>SOLUTION: A cooling system 10 for a rotary electric machine includes: a first motor generator 20, and a second motor generator 40, that are cooled by use of cooling oil 130; a first temperature detecting section 100, and a second temperature detecting section 101, that are in contact on respective first surfaces with respective flat portions of coil ends 204 and 404 and on respective second surfaces with the cooling oil 130; and a temperature calculating section 114 that calculates respective temperatures of the first motor generator 20 and the second motor generator 40 on the basis of characteristics maps that are created by determining previously a relationship among respective output voltages of the first temperature detecting section 100 and the second temperature detecting section 101, temperature of the cooling oil 130, and the respective temperatures of the first motor generator 20 and the second motor generator 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
