Yamaha Motor has completed development of an electric motor which it claims reaches the industry’s highest class in output density. This unit, which can be used in hyper-EV models to provide exceptionally high performance, is available for ordering for commissioned prototype development from this month. This would be useful for companies which are not established car companies with technical and financial resources for R&D but require a well engineered powertrain.

Maximum output up to 350 kW/476 ps
Since 2020, Yamaha Motor has been accepting commissions for developing prototype electric motors (35 – 200 kW/48 ps – 272 ps) for automobiles and other mobility applications. However, the company has also newly developed a unit boasting a maximum output in the 350 kW/476 ps 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.

Broad scope of prototype development
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.

Involved in high-performance Toyota engines
To many, Yamaha may be well known for its motorcycles although it has business units involved in various power units. It also has long experience in high-performance engines and helped Toyota develop and built the DOHC 6-cylinder engine in the 2000GT in 1967. The company was also involved in the development and manufacture of various Toyota twincam engines, among them to 2T-G and 4A-GE used n models like the Corolla Levin/AE86 and MR2. The V10 in the Lexus LFA was also developed with assistance from Yamaha.

Ford too commissioned the Japanese company to make a 3-litre DOHC V6 for its Taurus SHO model and it is known that the 4.4-litre V8 in the Volvo S80 and XC90 was developed with expertise from Yamaha too.
