Abstract
To exceed the top-level fuel efficiency of the 2009 Prius, a new motor was developed for installation in compact class hybrid vehicles including the new Prius. For the stator, segment coil stator with distributed winding was developed and achieved weight reduction and copper loss reduction. As for the rotor, highspeed, low-loss rotor was developed and achieved size reduction and volume of magnet used was reduced. Also, the motor cooling system was newly designed to improve the motor cooling performance. This paper describes the features of the new motor for the compact class hybrid vehicles including the new Prius.
