Magnetec Group

MAGNETEC

- Established in 1984

- started with cores for ground fault circuit breakers, a very common product

found in every household,

- MAGNETEC employs 700 people and generates revenues of 35 million EUR.

- MAGNETEC has manufacturing plants in Hungary and China and sales

representatives in Denmark, Finland, China, India and the USA.

- Another plant in Moldova is currently in the establishment phase

- Our main activities are in fast evolving markets such as renewable energies,

e-mobility and smart meters, and our customers comprise automotive industry

leaders, including electric car pioneer Tesla.

- As an expert in electromagnetic compatibility, MAGNETEC GmbH supplies soft

magnetic tape wound cores for all types of power electronics applications.

- Made from a special nanocrystalline material NANOPERM®, the cores are

exceptionally high in performance but very low in weight and compact in

design.

Nanoperm

Nanoperm is a rapidly quenched, iron-based alloy with a fine

nanocrystalline microstructure. Its typical grain size is 10

nanometers, thus the material name, “nanocrystalline”. This fine

inner structure is why it has extraordinary soft magnetic properties.

These properties can be controlled in a wide range by an

annealing process under the presence of external magnetic

fields.

Nanoperm

The requirements of the ‘new electricity age’ of our days are perfectly

met by nanocrystalline soft magnetic materials. This is because they

significantly provide:

o reduced size

o reduced weight

o lower loss

o higher temperature operation

✓ wide range of permeability from ~ 1.000 < r < 700.000✓ increased operational temperature range up to 180°C✓ excellent aging stability, highly durable

✓ highly linear properties with all respects

✓ various shapes of hysteresis loop from Z to flat

✓ advanced level of safety and reliability

✓ (almost) no Nickel, Cobalt or rare earth ingredients

Automotive Market

With the growth of E-Mobility, our Nanoperm material is

becoming increasingly important. The focus here is on the

entire EMC of the vehicle’s electrical system, specially

designed RCDs for personal safety in mobile charging devices

(ICCPD) and stationary wall boxes and public charging points.

Our nanocrystalline cores have proven their value for motor

bearing protection in the drive units of BEV or PHEV and for

personal protection. The special characteristics of the material

combined with our expertise enable us to work closely with our

customers to offer the most suitable product for the application

and to develop it to series maturity
