Publication number: 20090140601Abstract: In a rotary electric machine, for ensuring a cooling air flow between a rotor iron core and a stator iron core without enlarging a rotor, a separation preventing device is provided at a position between adjacent slots so as to correspond to each other at a shrink-fitting position where a retaining ring is shrink-fitted to a rotor iron core. Since a separation preventing position of the retaining ring is located at the shrink-fitting position, it is possible to reduce a length of the retaining ring itself so as not to be adjacent to the end portion of the stator iron core. Accordingly, a gap between the rotor iron core and the stator iron core does not reduce. As a result, it is possible to ensure a cooling air flow between the rotor iron core and the stator iron core without enlarging the rotor.Type: ApplicationFiled: November 28, 2008Publication date: June 4, 2009Inventors: Takayasu Tanaka, Hirohide Murayama, Kenichi Hattori, Kazuhiko Takahashi
