Yamaha launches 469-horse electric motor


Yamaha has been trying its hand at making an electric motorcycle for a long time. Several concepts have already been released, from the PES1 to the electric trial motorcycle, but none of them have gone into production yet. But despite the lack of progress in creating a flagship electric platform, the company released a series of so-called “boxed” electric motors – in English, this is the name for motors ready for swap, that is, direct replacement, they are supplied assembled in boxes.

Motor for electric supercars

A series of engines with power from 47hp to 268hp is intended for installation on motorcycles and cars instead of regular gasoline power units. And now Yamaha has expanded its first electric line to include a true flagship – a 350 kilowatt (469 horsepower) motor for electric supercars or other powerful devices and modes of transport. The internal permanent magnet synchronous motor operates on 800 volts and has an oil cooling system.

Exactly like the existing line of box-type electric motors:

The main feature of the new electric motor is its compact design, in which the mechanical and electrical components are arranged in a single compact module, which also includes a transmission and an inverter.

The integrated powertrain is reminiscent of the Triumph TE-1 electric motorcycle design concept (see details here), but Yamaha seems to have gone one step further. The fact is that Yamaha engines are deliberately designed to allow multiple motors to be installed on the same vehicle, thereby increasing the overall power of the powertrain. Unlike an internal combustion engine, combining electric motors to increase overall efficiency is not too difficult and costly.

To illustrate the system’s potentials, Yamaha has published a digital sketch showing four 350-kilowatt motors mounted on a car’s chassis – two in the front and two in the rear, connected together by a wiring harness. A four-wheel drive supercar constructed in this way will be capable of delivering 1,877 horsepower at its peak., and the electronic module that controls the electric motors will allow you to adjust the traction on each wheel and provide different drive modes, change the weight distribution on the axles and implement directional stability systems. Moreover, this technology will be available in the very near future: in April, Yamaha will start accepting orders for a new engine.

Of course, the target audience of the new electric motor is quite narrow, but the possibility of modular arrangement of the electric drive is very interesting. At a minimum, a separate electric drive for each wheel will allow the implementation of an automatic “differential lock” – that is, four-channel traction control that controls traction on each wheel according to different algorithms, and this is important not only for sports cars, but also for four-wheeled all-terrain vehicles.

And how this technology will affect the world of two-wheeled transport – we can only guess. Hopefully Yamaha’s flagship electric bike is just as fun!
