Motor coils / E‑mobility


Our com­pa­ny is a glob­al leader in the pro­duc­tion of seg­ment­ed motor coils. We also pro­vide our clients with years of expe­ri­ence and a num­ber of patents for devel­op­ing new products.

We design and produce these components for your applications:

● motor coils for hybrid vehi­cles
● sta­tor seg­ments for elec­tric super­charg­ers
● elec­tric bicy­cle motors for ped­elecs
● high­ly com­pact motors for robot­ic dri­ves, skate­boards, etc.

We also supplie inductive components for automotive charger systems (on-board charger, charger/inverter):

IGBT (and SMD) trans­form­ers
● pow­er induc­tors (and flatwire induc­tors)
● com­mon mode chokes





Current measurement technology


We design and man­u­fac­ture cur­rent sen­sors for pow­er switch­es, engine con­trol sys­tems, and elec­tric­i­ty meters:


are man­u­fac­tured as ener­gy and sig­nal trans­form­ers. Oval or round tape wound cores are used for the for­mer, while nanocrys­talline toroidal cores are used for sig­nal trans­form­ers. Our com­pa­ny is an expert not only in the pro­duc­tion of spe­cial appli­ca­tions in small quan­ti­ties, but also in mass pro­duc­tion rang­ing in the mil­lions, such as cur­rent trans­form­ers for domes­tic elec­tric­i­ty meters.

Rogowski COILS

 are avail­able as oval and round coils and are used by almost all glob­al­ly rel­e­vant man­u­fac­tur­ers in the pro­duc­tion of pow­er switch­es and cir­cuit break­ers. We spe­cial­ize in the high-pre­ci­sion pro­duc­tion of lin­ear Rogows­ki coils and appli­ca­tions with out­put sig­nals of over 2000V/kA.


As a tech­no­log­i­cal leader on the glob­al mar­ket, we also offer espe­cial­ly small high-pre­ci­sion Rogows­ki coils with the high­est immu­ni­ty to exter­nal fields.



We are an expert in the pro­duc­tion of cus­tomized sole­noid mag­nets for a wide vari­ety of appli­ca­tions and sizes — from “naked” mag­net­ic coils to ful­ly assem­bled mag­net assem­blies with con­trolled force-dis­place­ment monitoring.

Our product range includes:

● sole­noids (e.g. for igni­tion lock­ing devices)
● relay coils
● sole­noid valves
● sole­noids for door locks (e.g. for wash­ing machines)
● sole­noid trip­ping devices for pow­er switch­es and cir­cuit break­ers
● sus­pen­sion coils in motor vehicles


Ignition coils


We are also a reli­able part­ner in the design and man­u­fac­tur­ing of igni­tion coils and high-volt­age trans­form­ers for a wide vari­ety of appli­ca­tions. Thanks to decades of expe­ri­ence in the fields of wind­ing tech­niques, vac­u­um cast­ing, and high-volt­age-proof bob­bin design, we can offer you all the know-how required for volt­ages of 25 kV and more.

We are your partner for:

● igni­tion coils for oil and gas burn­ers
● igni­tion coils for gas dis­charge lamps
● high-volt­age trans­form­ers for photocopiers

Power supply units | Inverters | Drive control

Wound components fulfill key functions in modern power supply units and inverters.

Min­i­mum space require­ments, the high­est pos­si­ble insu­la­tion and par­tial dis­charge resis­tance, the use of insu­la­tion sys­tems, and the cor­rect nor­ma­tive design present the great­est chal­lenges. We have been man­u­fac­tur­ing com­po­nents in this sec­tor for over 50 years, result­ing in an unpar­al­leled wealth of expe­ri­ence in their design and production.


Whether you’re look­ing for cur­rent-com­pen­sat­ed fil­ter chokes with fer­rite cores or mod­ern nanocrys­talline solu­tions, we will always have the tech­ni­cal­ly and eco­nom­i­cal­ly opti­mal solu­tion. This also applies to trans­form­ers in a vari­ety of cir­cuits in clocked switched-mode pow­er sup­plies, con­trol trans­form­ers in IGBTs, and sim­i­lar prod­ucts. Our com­pa­ny use and sup­plie coils of every con­struc­tion type (e.g. e‑cores, toroidal cores, RM, and PQ), with all com­po­nents tai­lored to your requirements.

Measurement & energy transformers for circuit breakers (ACBMCCB)


We are a glob­al mar­ket leader in the design and pro­duc­tion of com­plex mea­sur­ing mod­ules for a wide vari­ety of low, medi­um, and high volt­age cir­cuit breakers.

Mod­ern devices use sep­a­rate pow­er sup­ply sys­tems for elec­tron­ic trip­ping units and to detect load and short-cir­cuit cur­rents. High-pre­ci­sion Rogows­ki coils, which are resis­tant to exter­nal fields, are used for the lat­ter due to their lin­ear­i­ty and large range of mea­sure­ment, while for elec­tron­ic appli­ca­tions we use ener­gy trans­form­ers based on SiFe cores man­u­fac­tured by us. We install both coils in com­plex sys­tems con­sist­ing of plas­tic parts, cast­ing com­pounds, join­ing tech­nol­o­gy, and oth­er components.

All sys­tems are designed and man­u­fac­tured accord­ing to the customer’s spec­i­fi­ca­tions in order to meet the high­est require­ments and cre­ate the most com­pet­i­tive end prod­ucts possible.

Immobilizers | Anntennae | Sensors


Micro­elec­tron­ics have rev­o­lu­tion­ized the auto­mo­tive indus­try. Today, the indus­try uses a wide range of tech­nolo­gies. WE make this pos­si­ble with a vari­ety of high-tech com­po­nents, such as sole­noids, sen­sors, and transformers.


By using of state-of-the-art pro­duc­tion tech­nolo­gies in the com­bined wrap­ping and over­mold­ing of coil bob­bins, we are able to devel­op and pro­duce these com­po­nents in line with the customer’s require­ments and spec­i­fi­ca­tions. They serve as an inter­face between mechan­i­cal and elec­tron­ic com­po­nents and are used as immo­bi­liz­ers that trans­mit sig­nals from mod­ern igni­tion keys to the vehi­cles, as sen­sors that detect indi­vid­ual tire pres­sure lev­els, and as anten­na coils that detect exter­nal vehi­cle guid­ance signals.

Development & Industrialization


Indus­tri­al and auto­mo­tive com­po­nents are only as good as their design and the pro­duc­tion meth­ods used to man­u­fac­ture them. We pro­vide sup­port to our cus­tomers in cre­at­ing the opti­mum design for all com­po­nents. We also design and man­u­fac­ture all the nec­es­sary tools and auto­mat­ed pro­duc­tion facilities.

Our com­pa­ny designs and makes all the nec­es­sary com­po­nents, from injec­tion mold­ing tools to robot­ic man­u­fac­tur­ing process­es and ful­ly auto­mat­ic final inspec­tion facil­i­ties. Our spe­cial divi­sion engi­neers guar­an­tee that your prod­ucts are man­u­fac­tured to the high­est qual­i­ty stan­dards and as eco­nom­i­cal­ly as possible.
