Yamaha Motor Co., Ltd. has informed recently 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 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
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
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.
Yamaha Motor plans to exhibit the 350 kW class unit and its
other electric motor prototypes at the Automotive Engineering Exposition 2021
Yokohama scheduled for May 26 to May 28, 2021.
