Component & Test Bench Supplier REO Positions for Electrification Trends
mission now is to communicate this and to secure a leading position
in the competitive environment. " The site positions REO
AG as a holistic partner in the development, production, testing
and maintenance of electromobility solutions. The focus is on
components for the electrification of power trains and electric
engine peripherals, components for charging stations, wall
charging stations and wall boxes, and test technology.
In the field of medical technology, transformers, filters, chokes
and current transformers from REO are critical components for
transforming and controlling electricity while protecting equipment
and patients. Vertical integration of the complete production
process is a hallmark for the company.
Global trends in increased electrification are creating new challenges
and opportunities for companies involved in magnetics.
In our ongoing reporting of how they are adapting, REO AG
stands out for thoughtfully addressing the evolution, especially
related to e-mobility and medical devices. A manufacturer of
electrical components and test benches, REO is a fourth-generation
family held company based in Sollingen, Germany with
about 400 employees and 11 sites globally.
" Electricity is what makes REO's heart beat. We believe it is the
future of mobility, " the company says. With the ongoing move
towards electrification, it has bundled together and considered
in a logical manner its strengths in the production of inductive,
resistive and electronic components. While many providers are
forced to purchase technologies, REO can revert to more than
95 years of experience and in-house capability. Recent comments
by some of its managers and executives help articulate
the view.
" Electric motors are extremely efficient when compared to
conventional motor types like the combustion engine " , explains
Sven Reimann, management board member and head of
development. " At the same time, e-motors benefit from energy
recovery during braking, low noise level, simple design and do
not cause any local emissions. With REO's components, we are
able to make our contribution to improving e-motors and making
them more efficient. "

" We had already recognised at an early stage
the change in social awareness and resulting
potential in the field of e-mobility, " notes
Jasminka Usein, board member. " As a result,
the research and development work activities
we have undertaken previously are now paying
dividends. We offer a unique product portfolio
globally with our intelligent and smart test
systems that can be used in almost any area
of e-mobility. "
" We recognized a change in social awareness,
and the resulting industrial potential in
the field of electromobility, at an early stage.

Kyritz branch. Commenting on the firm's
new electromobility website, she adds: " Our
" We worked out at an early stage that high levels
of globalization combined with the transfer
of production to countries located far away
posed particular risks to sensitive medical technology
components, explains Philip Twellsieck,
chairman of the management board of REO.
As a result, excellent medical device quality
is achieved due to the holistic production
methods employed in REO's German plants.
All of the skills required are pooled together
within the company to safeguard production
and deliveries.

" All of our medical devices have been designed to ensure the
maximum level of safety " , notes Wolfgang Senninger, head of
the REO Medical and Current Transformer Division. " This not
only protects patients, it also ensures the safety of the doctors
and medical personnel administering care.
REO edge winding for power efficiency and weight reduction

" Energy efficiency is a key factor in the company's designs. For
example, by using edge winding in some of its products REO is
able to achieve efficient cooling due to single-layer design. Due
to the better cooling, an aluminium conductor can be used as a
replacement for copper conductors, depending on the design.
Skin and proximity losses are reduced, important for the use of
silicon carbide and gallium nitride-based semiconductors. Due
to the lower winding capacity, the high edge winding is also
suitable for higher frequencies. Virtually no insulation material
is required, thus increasing service life.
