The hybrid vehicle, the 'PRIUS,' placed on the Japanese market by Toyota Motor Corporation for the first time in the world, has managed to popularize advanced technology. Before introducing it to the US and European markets, the authors have improved its engine, motor and transmission to achieve higher output power and higher fuel efficiency. This paper describes technologies and improvements in the new drive motor and the generator for the THS. The main characteristics of the improved motor and generator are as follows: Permanent magnet-embedded rotor for higher output power, improved efficiency and downsizing; optimum flux-weakening control in accordance with battery voltage for higher efficiency; 1-pulse switching control for higher output power and efficiency in high revolution range; oil seal-less motor for lower mechanical loss.
