Yamaha Motor begins accepting orders for prototype Hyper-EV electric motor development

— New electric motor reaches 350 kW class in maximum output —

Yamaha Motor Co., Ltd. (Tokyo: 7272) announced today that it has developed an electric motor reaching the industry’s highest class in output density. This unit is aimed at use in hyper-EV models and other offerings in the high-output mobility segment and Yamaha will begin accepting orders for commissioned prototype development from April this year.

Since 2020, Yamaha Motor has been accepting commissions for developing prototype electric motors (35–200 kW) for automobiles and other mobility applications. However, the company has also newly developed a unit boasting a maximum output in the 350 kW class (operating voltage of 800V) intended for installation and use in hyper-EVs and other high-output applications.

The main feature of this newly developed electric motor is its compact construction that treats the mechanical and electrical components as a single entity, integrating the gear and inverter into one unit. It was also developed in anticipation of installation and use of multiple units on a single vehicle.
Regarding commissioned prototype development, Yamaha will leverage its production technology and know-how in the casting, machining and assembly fields that give the company the flexibility to adapt to the needs of motorcycles and its numerous other products, its prototyping equipment and facilities and more in order to develop prototype motors tailoring to the specific requirements of clients in a short period.
