LG Innotek Challenges Japan and China Dominance in Fundamental Magnetics Innovation
LG Innotek strives to change the landscape for dominance in fundamental magnetics innovation with its eco-magnet and ultra-thin ferrite magnetic
components
With accolades for its new Nexlim, which it calls " the world's
thinnest magnetic component " , and the recent development of
its " eco magnet " , Korean materials and components company
LG Innotek is making impressive headway in challenging the
dominance of companies in China and Japan for leadership of
innovation in fundamental magnetics technology.
In late April, the company won a prestigious Edison Award for
its Nexlim magnetic component designed to open a new era of
ultra-slim and ultra high-definition TV. It won a bronze award in
the commercial technology category for engineering and robotics
in the annual competition, often referred to as the Oscars of
Innovation. More than 3,000 judges composed of executives and
scholars from industrial fields across the US participate for strict
review and evaluation conducted for over seven months. Gold,
silver, and bronze winners are chosen annually in 16 fields.
At the heart of the product is innovative
ferrite material developed by LG
Innotek to make high-definition thinscreen
televisions which now, the
company reports, is being advanced
for applications in electric vehicles.
LG Innotek calls Nexlim the
world's smallest magnetic
component
Nexlim is a magnetic component
that is mounted on the TV power
module, vehicle power and chargers
to change the voltage, or to perform
the role of removing unnecessary
signals that are generated from the
current waves. It plays an important
role of minimizing the power loss
from heat generation to increase the

energy efficiency of electronic products and electric vehicles.
The popularity of ultra-slim, high-definition TV with bigger screen
and thinner size has challenged TV manufacturers in their
product design. The volume of magnetic componentry such as
transformers and inductors have had to be increased more than
three times, and reducing the TV thickness at the same time was
technologically impossible. Development of an ultra-thin magnetic
component to replace the existing magnetic component that
occupies half of the overall TV thickness has been a major priority.
At first, LG Innotek succeeded in commercializing Nexlim with
9.9mm in thickness. The technology was enhanced even more to
lessen this to only 7mm last year.
The key to minimize thickness
is a high-efficiency
ferrite that is used as the
main material in Nexlim.
LG Innotek independently
developed and applied the
ferrite magnetic material (X2)
to reduce the energy loss
up to 40% compared to other
general magnetic materials,
and to increase the power
density by three times.
Research Fellow Bae
Seok, developer of Nexlim,
explained that " By introducing the simulation system utilizing AI,
we were able to find the optimum material composition ratio for
maximizing the ultra-low loss and high efficiency performance in
just 6 months, " and added " The inductor and transformer, parts

'Ferrite (X-2)', high-efficiency magnetic
material used as a main material
in 'Nexlim'. A new generation,
X-3, will be applied to EV technology.
