Title: Motor
Inventor: NABESHIMA KATSUHIRO
IPC: H02K9/19
Filed: 2007-04-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor wherein it is possible to suppress variation in internal temperature distribution and achieve more effective cooling.  <P>SOLUTION: A rotor 8 is rotated together with a shaft 3 and churns up retained insulating oil OL by its portion 8c holding a magnet 8b. Part of the insulating oil OL churned up becomes an oil droplet and sticks to the outside of a stator 7. The oil droplet draws heat from the stator 7 and then drops. Another part of the insulating oil OL churned up becomes an oil droplet and sticks to the inner wall of a case 1. The oil droplet gives heat to the case 1 and then drops. When churned up by the rotor 8, the retained insulating oil OL draws heat from the rotor 8. When the above operation is repeated, the temperatures of the stator 7 and the rotor 8 drop and the temperature of the case 1 rises. However, since the case 1 exchanges heat with the cooling water passed through its water jacket 1a, the temperature of the case is prevented from becoming high.  <P>COPYRIGHT: (C)2009,JPO&INPIT
