| Outline of Final Research Achievements |
In this study, the reduction system of windage power loss used for a main motor of electric vehicles was proposed which could reduce the surrounding pressure of a motor rotor. It was confirmed that the proposed system installed in a motor housing could achieve the pressure reduction of 0.03 MPa at speed of 15,000 rpm. In addition, the authors developed newly designed reduction system of windage power loss which could be installed outside of a motor housing. As a result, it was found that the new system could reduce the pressure over 0.03 MPa at speed of 25,000 rpm and the seal clearance of 16 um.
