MAHLE Develops Highly Durable Electric Motor
time, the extremely compact design results in an advantage in
the costs of materials and weight-a lighter motor requires less
material during manufacture and increases the possible net load
in commercial vehicles.
Compact endurance athlete -the new SCT E- motor by MAHLE on the
test bench
The automotive supplier MAHLE has developed a traction motor
which is unique on the market and can run indefinitely with high
performance. A new cooling concept makes this technological
leap possible. The new electric motor is surpassingly clean,
light, and efficient and can be assembled without the use of rare
earths by customer request. The new development is suitable for
passenger cars and commercial vehicles as well as construction
machines and tractors. With the SCT E-motor, MAHLE thus becomes
a full-range provider in the field of electric drives and covers
all needs from e-scooters to heavy-duty commercial vehicles
as well as off-road and industrial applications. The new item was
presented for the first time at IAA Transportation in September
2022 in Hanover.
" Building large electric motors that deliver short-term high performance
is easy. What was still lacking on the market until now
were durable yet compact drives to make electric vehicles unrestricted
for everyday use, " said Martin Berger, Vice President
Corporate Research and Advanced Engineering at MAHLE. " Our
new SCT E-motor is the solution. "
On the drivetrain side, this clears the way for the replacement of
the combustion engine in all vehicle classes. In 2021, MAHLE
presented a groundbreaking wear-free and scalable traction motor
for passenger cars that runs very efficiently over a wide rpm
range.
The SCT E-motor, on the other hand, is designed in such a way
that it is particularly efficient within a certain rpm range. Despite
its very compact and light design, its continuous output is more
than 90 percent of its peak output. Unique on the market, this
groundbreaking high ratio means a technological leap and allows
the use of electric vehicles of all kinds even under demanding
conditions. A classic example is driving an electric truck over
mountain passes or the multiple sprints of a battery electric passenger
car. These scenarios are only insufficiently covered by
the electric motors available on the market up to now.
This resilience is achieved by the new MAHLE electric motor
through the use of an innovative integrated oil cooling, which not
only makes it more robust but also allows the waste heat generated
to be used in the vehicle's complete system. At the same

Users of magnetic particle testing value trouble-free preparations
and eco-friendly solutions these days. In response, Marktec of
Japan brings to the market an array of magnetic particle fluids

Innovative cooling prevents overheating - even during continuous
operation with 90 percent of the motors peak performance.
In designing the product, MAHLE opted for what is known as a
permanently excited motor, since this type enables a very compact
design and no energy has to be transferred to the rotor as
" excitation current " . This makes the motor efficient and wear-free.
Neodymium magnets, currently the strongest permanent magnets
that can be produced, are used to generate the magnetic
field in the motor. However, to achieve greater independence
from raw material prices and geopolitical developments, the
SCT E- motor can also be designed without magnets for greater
independence. Thanks to the unique contactless transformer
developed by MAHLE, the magnet-free variant would also be
wear-free and run efficiently, while only requiring slightly more
assembly space.
