Amorphous Soft Magnetic Alloy for Motors

These Nd-Fe-B (neodymium-iron-boron) sintered magnets provide the highest level magnetic properties and are used in the traction motors forelectric and hybrid vehicles as well as for other applications. NEOMAX®̶which Proterial was the first in the world to develop and bring to mass
production̶withstands a broad range of environmental conditions from room temperature to much higher temperatures around engines.
In addition, we have been developing magnets that use less heavy rare earth. These environmentally friendly products with superior
magnetic properties contribute to smaller size, lighter weight, and better efficiency for our customers. We are still accelerating thedevelopment of magnets that use much less heavy rare earth and expanding product lineups to meet our customersʼ needs.

Amorphous soft magnetic alloy is prominent core materials for use in next-generation
high-efficiency motors. With about one-tenth the iron loss of non-oriented magnetic steel
sheets, these materials contribute to core loss reduction in motors.

NMFTM series ferrite magnets
Ferrite magnets, which consist primarily of iron oxide, are costeffective and the most widely used magnets in motors for automotive
electrical components. Among the NMFTM series, NMF-15 is theworldʼs leading mass-produced ferrite magnet in terms of magnetic

FINEMET® Nanocrystalline Magnetic Alloys
FINEMET® is the worldʼs first nanocrystalline soft magnetic alloy developed by Proterial. This new Fe-based
soft magnetic alloy is composed of nanocrystals. It has high saturation induction, high permeability, excellent
temperature characteristics and temporal stability. FINEMET® is utilized in high-frequency power transformers,
noise-suppression components and other applications where it contributes to downsizing and lightening.

FINEMET® Common Mode Choke
Cores and Coils
Instilled with high magnetic permeability and low Q factors, thesecores and coils furnish high impedance over a broad frequency range,
allowing them to manifest major noise suppression effects. Moreover,because impedance does not vary widely by temperature, stable noise
suppression effects can be obtained over a broad temperature range.

Aluminum Cases Containing EV/HEV Components(Battery and Inverter)
These Aluminum cast cases are manufactured by a gravity die casting processes. They help reduce the weightsof the Battery unit because of their material composition and higher freedom in shaping. And the cases may

Soft Ferrite Cores

Amorphous Powder Cores/Coils

Isolating Transformers

Although these cores have a lower saturation flux density than othersoft magnetic materials, their electrical resistance is higher, and they
are characterized by overwhelmingly excellent magnetic properties inhigh-frequency bands from 100 kHz to several tens of MHz. With theaddition of the MaDC-FTM series, which have low losses in thehigh-frequency range, these products help to make passive
components smaller, lighter, and more efficient in many fields,
including xEV, mobile devices, and industrial equipment.

These cores and coils are designed to combine high saturation flux
density and low loss by using a Fe-based amorphous metal
powder. They are suitable for smoothing choke coils for both
input and output of power supply, choke coils fornormal-mode noise reduction, and choke coils for power
factor correction circuits. The coils are able to operate
at frequencies as high as 100 kHz and contributeto making equipment smaller and more efficient.

These transformers use ferrite cores that are less likely to saturate
during high-temperature operation and employ our original isolating
structure to achieve high dielectric strength and a compact body.

They are suitable for smoothing choke coils for both input andoutput of power supply, choke coils for normal-mode noise

circuits. The coils are able to operate at frequencies
as high as 100 kHz and contribute to making
equipment smaller and more efficient.

Although these cores have a lower saturation flux density than othersoft magnetic materials, their electrical resistance is higher, and they
are characterized by overwhelmingly excellent magnetic properties inhigh-frequency bands from 100 kHz to several tens of MHz. With theaddition of the MaDC-FTM series, which have low losses in thehigh-frequency range, these products help to make passive
