Takeshi Ikemi, NISSAN MOTOR CO.,LTD
We introduce the development of the drive motor used on a newly developed electric vehicle (EV) that has been specifically designed and engineered as the worldâ€™s first mass-produced EV. Producing maximum power of 80kW, this synchronous motor was selected as the first electrified powertrain to be named to Wardâ€™s 10 Best Engines list for 2011. In developing this motor, magnetic field analysis were conducted in the process of adopting the following in-house technologies to achieve a compact motor size, high output and high efficiency. We will explain the study of Leafâ€™s motor development by using magnetic field analysis.
