Proterial Builds Ferrite-Magnet Motor Prototype, Adds AI to Its Toolkit for Developing New
Materials
For design engineers,
simulations can be important
tools in the product
development process but
actual performance by
a prototype is a welcomed
step better. That's
the status at materials
company Proterial where
a prototype motor built
with its innovative new ferrite magnets confirmed the promising
results from an earlier simulation model - challenging
the performance of neodymium magnets in EV
motors. Separately, the company announced that
it is embracing artificial intelligence techniques in
its efforts to develop more new advanced materials
serving a variety of markets.
Formerly Hitachi Metals, Proterial reports it has
achieved an output exceeding 100 kW from a
prototype ferrite-magnet motor which breaks
into the realm of traction motors for electric and
hybrid-electric vehicles that typically use rare-earth
neodymium magnets. Following up on the simulations
announced in December 2022, and previously
reported in Magnetics Magazine, Proterial
proceeded to develop a prototype motor using its
NMFTM-15 high-performance ferrite magnet and
evaluated its performance.
This motor uses a rotor (see photo above) that was
designed and fabricated based on results from
the simulations. A neodymium magnet motor for
driving xEVs was used as the basis for comparison.
Performance tests confirmed that, although
performance was slightly lower than that shown in
simulation results, an output in excess of 100 kW
can be obtained.
Going forward, the development team is verifying
the difference between the results from simulations
and results of tests on the actual motor to look into
the possibility of making further improvements in
motor performance. Ferrite magnets have higher
electrical resistance than neodymium magnets,
and therefore contribute to suppressing eddycurrent
losses at high rotation speeds. According
to the company, its proprietary material exhibits
among the world's highest level of magnetic properties
as a mass-produced ferrite magnet as of
data available on June 2023.
AI for new materials development
On November 20, Proterial announced that it has
developed a proprietary materials informatics
platform, called D2Materi, that takes a data-driven
approach in estimating materials characteristics
and designing new materials. It extracts the correlation
between materials performance or composition
and processes, laws, and characteristics from

accumulated data, including data of metallic materials.
Material design modelling using the platform can improve the
accuracy of extrapolation since it is equipped with a unique
proprietary algorithm that utilizes generative AI. The platform can
estimate data outside a known range, from actual data obtained
in experiments. It is also highly capable of estimating conditions
for producing materials having new properties, says the company.
