Braided Windings & No Rare Earths in ZF 800-Volt e-Drive for Passenger Cars
Based on a Porsche Taycan, ZF's EVbeat concept vehicle sports a drivetrain with special braided motor windings and without rare earth magnets.
" Sustainable
mobility is at the core of our corporate strategy, "
says Stephan von Schuckmann, member of the ZF Board of
Management responsible for electrified driveline systems. " Based
on an extremely efficient production vehicle, we are showing
the potential that future electric drive components offer when we
combine them into an even more efficient overall system. " The
technology is embodied in its EVbeat concept vehicle which is
based on a Porsche Taycan and takes leading series technology
from ZF and other market players as a benchmark.
" Our goal was to make this drive as compact and lightweight as
possible while maintaining high driving dynamics and increasing
efficiency in real-world operation, " said Dr. Otmar Scharrer, head
of development for electric driveline systems at ZF. " In terms of
torque density, we are at the top of the podium when we compare
ourselves with e-drives for passenger cars currently available
on the market. At the same time, we paid strong attention to the
sustainability aspect during development. "
The electric motor works without heavy rare earths and the thermal
management system does not use fluorine-based coolant.
The reduced number of components and the overall 30% reduction
in system weight for the electric drive and thermal management
system make a double contribution to greater sustainability,
both in production and operation.
EVSys800: ultra-compact and
lightweight 800-volt drive
EVSys800 is a modular 800volt
drive and consists of silicon
carbide power electronics, the
electric motor and a reduction
gearbox. Despite its extremely
compact design and light weight,
it does not skimp on performance.
The concept vehicle has a
maximum torque of 5200 Newton
meters available on the rear axle,
Stator with the new braided
winding
and this with a uniquely high torque density for road-legal passenger
cars with of 70 Newton meters per kilogram. The continuous
and peak power of the electric motor is 206 and 275 kilowatts,
respectively, achieving continuous power of around 75% of the
peak power.
New generation of the EVSys800 e-drive from ZF has a power density
of 70 Newton meters per kilogram of drive weight
In terms of dimensions, the drive saves 50 millimeters in width
thanks to the compact reduction gearbox and the ZF-patented
braided winding technology of the electric motor, thus enabling
space-saving, coaxial installation on the drive axle. With a total
