<P>PROBLEM TO BE SOLVED: To further accurately detect a temperature of an electric motor, in the electric motor in which a stator is formed by assembling a plurality of divided cores to a stator coil formed into a cage shape. <P>SOLUTION: Grooves 36a, 36b for penetration hole formation are formed at the divided cores 30a, 30b, and a conductive line 28 from a temperature detection element 26 attached to a coil columnar support 23a of the stator coil formed in the cage shape in advance is wired. By forming the grooves 36a, 36b at the divided cores 30a, 30b, the temperature detection element 26 can directly be attached to the stator coil 22. As a result, the temperature of the electric motor can further accurately be detected without receiving an influence of cooling oil. Owing to this, it is not necessary to take a large margin at an allowable upper-limit temperature of the electric motor, and the performance of the electric motor can further favorably be exhibited. <P>COPYRIGHT: (C)2011,JPO&INPIT |
