14.4.2021Yahama shows off high performance electric drive
Yamaha Motor has developed an electric motor with a maximum output of 350 kW. According to the Japanese company, the drive module can be used in “hyper EVs” and other high-performance applications.
The electric drive system works with 800 volts operating voltage and is supposed to offer an enormously high power density. The electric motor is an “integrated permanent magnet synchronous motor” (IPMSM) that is oil-cooled. All mechanical and electrical components (for example, the gearbox and the inverter, respectively) are integrated into one unit, which should enable a particularly compact design.
350 kilowatts or 476 hp in the old world is already more than sufficient power for a car, but this level of performance is now achieved by the top sporty models of many a mid-range saloon. In order to push into the performance regions of a hypercar, the drive unit was developed, according to Yamaha, in such a way that several units can be installed in one vehicle. With four electric motors (one on each wheel) a corresponding hypercar would have an output of 1,400 kW or 1,904 hp.
Yamaha has not yet given any details about torque, weight or dimensions. The prototype of the new 350 kW unit is to be exhibited at the Automotive Engineering Exposition 2021 in Yokohama at the end of May, when there may be more details about the drive and plans from the Japanese company, which builds motorbikes and outboard motors.
Regarding the 350 kW powertrain, Yamaha adds in a footnote that the model is still under development and the figures could change. The maximum power and also the cooling method could still be adjusted or changed according to customer requirements.
Yamaha does not want to build an electric hypercar, or electric cars in general, but could develop them on customer order. Since 2020, Yamaha Motor has been developing electric motor prototypes for cars and other forms of mobility on behalf of customers. So far, these have been in the power range of 35 to 200 kW.
