Armed with state-of-the-art manufacturing and a history of innovation, Schaeffler
Group is attacking the e-mobility space, says Daniel Sayre.

T
he vehicle-electrification trend has caused the
industry's " traditional " suppliers to bring new
strategies, tactics and investment to meet a
growing tide of EV development programs.
Some long-serving companies have had to scramble
and essentially reinvent themselves. For others, including
75-year-old Schaeffler Group, the transition has
been more seamless. Schaeffler notably read the forecasts
correctly and has been steadily building e-mobility
muscle as it positions itself for the electric future.
" E-mobility technology is new in some ways, but the
methods to implement it in production are the same
as they've always been, " noted Daniel Sayre, director
of the eMotor and PEU [power electronic] business
unit at Schaeffler North America, based in Wooster,
Ohio. " We're just configuring our many 'building
blocks,' some of them a century old such as our bearings,
in new ways. "
For Schaeffler, which invented the needle-roller bearing
in 1946, much of the basic development process
used for the company's extensive range of products for
30 September 2021
combustion-engine powertrains and industrial applications does not
change for electrification, Sayre told SAE Media. The engineering organizations
responsible for simulation, design, prototyping and testing
aren't fundamentally changing for EVs - " they're just learning another
new product, " he said.
Winding up the assets
Anticipating the global " all in " on EVs, Schaeffler created its fastgrowing
E-Mobility Group in Wooster to serve as a center of expertise
for the Americas that is diving deep into electric motors, e-axles,
fuel cells, actuators and related technologies.
Electric motors were a fairly dormant technology for the past century
but reawakened over the last decade by the modern electric vehicle.
" The advancement curve for e-motors is shaped like a hockey stick, as
we focus on greater power density and efficiency while remaining cost
competitive, " Sayre explained. " This means advancements in material
utilization and in industrialization. These are extremely critical and are
things that Schaeffler, with our vertical integration, legacy technologies
such as bearings and clutches, and global footprint, does very well. "
He said the well-honed systems approach to development and
