A Revolution in EV Motor Technology
YASA Axial Flux Technology has been pushing the performance EV revolution for over 10 years.
Now, as part of Mercedes Benz, YASA Motors bring up to 4 X more torque and double the power densities of current technologies used in nearly all Electric Vehicles, whilst being 50% lighter and 20% of the depth of a typical radial machine.
Increased Opportunities for Driver and Designer
The YASA Axial Flux Motor provides the performance driver with an unmatched electric driving experience. Possible due to it’s unique engineering characteristics, opening up a new world of potential for vehicle designers.
More power dense than the competition
You can rely on the YASA Axial Flux Motors to give you up to an incredible 480 hp. The YASA motor topology also removes the stator yoke, which reduces the stator iron mass by up to 80%, meaning YASA motors are 2-3x the power density of non axial machines.
Unrivalled torque density
YASA Axial Flux takes this to the next level. Torque is Force x Radius, so the increased radius of an axial machine immediately increases the figure. Something not possible within the heavyweight confines of a radial machine. Coupled with much shorter, optimised copper windings, the result is an electric motor that delivers up to 800nM, or 4x the Torque Density of other EV motors.
Endlessly repeatable performance
The YASA Axial Flux Motors benefit from much shorter windings and direct oil cooling which gives an unparalleled performance proposition.
A 200kW peak-power radial motor, run continuously, might typically give 50% of peak power between 80 and 100kW, as a result of thermal limitations.
In contrast, a 200kW YASA motor runs continuously at 150kW thanks to the improved high-thermal-contact cooling that oil offers.
50% smaller
YASA Axial Flux Motor takes 50% less volumetric space than the radial equivalent. This space saving allows designers and developers new possibilities. New possibilities YASA are already exploring
50% less weight
1) YASA decreases the weight of motors in an EV, providing manufacturers the opportunity to achieve 5-10% greater efficiency and range versus a radial machine.
2) Maintaining the range instead provides opportunity for a reduction in battery size, lowering weight further
3) Reduced vehicle mass therefore means smaller/lighter brakes, again increasing range
4) All these changes require reduced associated systems, resulting in further efficiency improvements
Reduced complexity and materials.
Our motor efficiency is not limited to its performance capability.
The YASA Axial Flux approach uses less material such as copper, iron and permanent magnet, than conventional e-motors, resulting in a significantly lower material cost and a more environmentally-sustainable product.
