In coil production, the wire used plays a central role. While copper is undoubtedly the most commonly used conductor material, especially for customer-specific coil projects, it is also worthwhile to test alternative coil wire, depending on the application. Read more
Both the AWG and metric system (mm) are used in coil design. The choice between them depends on the application, regional and personal preferences of the engineer. Both scales have advantages and disadvantages, and it’s important to be familiar with both and convert between them as needed. Read more

KUK Group offers the entire package from coil production to the assembly of a complete motor from a single source. High flexibility and fast turnaround times are the biggest advantages for the customer. Read more
De afmetingen van microspoelen zijn vaak moeilijk te bevatten. Hier zie je een vergelijking met een vingertop. Dit zijn enkele honderden windingen met een ultradunne draad. Dit zijn echt nog niet de kleinste spoeltjes!
Bij de KUK Group worden klantspecifieke spoelen en elektronische assemblages grotendeels geproduceerd op in-house ontwikkelde geautomatiseerde systemen. Dit betekent dat wij u een zeer aantrekkelijk spoelen-productieproces kunnen aanbieden op het gebied van kwaliteit en prijs, afgestemd op uw volume en technische specificaties. Lees verder
Bij het edgewise wikkelen wordt de wikkeling van de spoel loodrecht op de as van de spoel gewikkeld, in tegenstelling tot de meer traditionele axiale wikkelmethode waarbij de wikkeling parallel aan de as wordt geplaatst. Het kiezen voor een edgewise spoel hangt af van de specifieke vereisten en behoeften van de toepassing.
“De door jullie verzonden spoelen … waren zeer indrukwekkend qua kwaliteit. Als onze [andere] leveranciers slechts 50% van de door u geboden kwaliteit zouden leveren, zou mijn leven wat gemakkelijker zijn. Wij beschouwen uw spoelen hier als ‘standaard’ – moeilijk te overtreffen!” Lees verder

Sometimes it is quite human reasons that trigger a search for a supplier. At Bürki inno med AG from Widnau (Switzerland), the retirement of an employee prompted the search for a coil supplier with proven medical technology experience. Until then, the developer and manufacturer of microsurgical instruments for ophthalmology had wound its own coils by hand. Within a few months, production was then transferred to KUK Group, the world’s leading manufacturer of customised coils and electronics. “This is an enormous relief for us. The process stability could be improved and the testing effort considerably reduced,” says Martin Bürki, founder and partner of Bürki inno med. KUK produces a wound coil for the medical technology manufacturer, which is cast in the housing. It is used to drive a handpiece for eye surgery. Read more

Recent is op de vestiging van KUK Wijdeven in Ter Apel een nieuwe Giebler ingietmachine in gebruik genomen. Een lineaire machine met drie X-, Y- en Z-assen en met meng- en doseersystemen voor het automatisch ingieten met polyurethane ingietmiddelen. Snel, nauwkeurig en seriematig ingieten is nu mogelijk met de hulp van specifieke productdragers. Naast atmosferisch- behoort ook vacuüm ingieten tot onze mogelijkheden. Wellicht ook voor uw transformatoren of spoelen?
De Rotary transformator wordt gebruikt om elektrische signalen te koppelen tussen twee delen die ten opzichte van elkaar roteren. Een beter alternatief dan sleepringen die onderhevig zijn aan slijtage. Er zijn twee vormen van constructie mogelijk “cylindrical” of “pancake” bouwvorm. Bij de “Cylindrical” liggen de kernen en windingen in elkaar en bij de “Pancake” op elkaar. Dit is de rotorspoel. Het stator gedeelte ligt op een ander werkblad klaar om ingebouwd te worden. Cylindrical voor deze klant.
Wijdeven is in Nederland één van de toonaangevende producenten van 50 Hz transformatoren in het laagspanningsgebied. Al sinds 1939 wordt dit vakmanschap van generatie op generatie overgedragen. De aanvankelijk ambachtelijke wikkeltechnieken zijn inmiddels vervangen door semi- en volautomatische productielijnen, maar in de kern gaat het nog steeds over de vraag: ‘Hoe bouwen we een veilige transformator?’. Dit vormt de basis van ons dagelijks denken en doen. Lees verder
Our coil and transformer are used in a test setup for a magnificent project at the University of Twente department “Magnetic Detection & Imaging”. Project number 14322 ‘magnetic sensing for laparoscopy (MagLap)’, financed by NWO-TTW.
Detection of the sentinel lymph node (SLN) in cancer patients can overrule the requirement for resection of all regional lymph nodes, which leads to decreased morbidity. The use of magnetic nanoparticles has many advantages over nuclear tracers, which are the current standard to detect SLNs. The principle used to achieve SLN detection is differential magnetometry (DiffMag). Read more [Source: utwente.nl]
De 2250VA transformator, is jaren geleden speciaal ontworpen voor dialyse apparatuur. Door de introductie van nieuwe dialyse apparatuur met zwaardere vermogens is gebleken dat de standaard 2250VA transformator vaak niet meer toereikend is, en de 3150VA of 3300VA in principe over-gedimensioneerd is.
Deze trend heeft Wijdeven aangegrepen om een medische beschermingstransformator te ontwikkelen, met een tussenliggend vermogen van 2600VA. Lees verder
Voor het elektrisch meten van spoelen en transformatoren is onze Quality Department uitgerust met deze nieuwe ‘Voltech AT5600’ meetmachine. Het stelt ons in staat om nog sneller dan het vorige model uitgebreide testen uit te voeren en op te slaan.
Veiligheid en continuïteit van elektrische installaties in medische ruimten zoals operatie- en behandelkamers zijn van levensbelang. Daarvoor worden medische transformatorkasten ingezet. Deze installaties dienen aan de veiligheidseisen conform NEN1010-7 te voldoen, waardoor patiënten en artsen optimaal worden beschermd in het medische IT stelsel (bijv. tegen te hoge lekstromen of netuitval). Door het toepassen van DEKRA geaccrediteerde beschermingstransformatoren van Wijdeven creëert u een veilige situatie in uw medische ruimte. Lees verder
De meest eenvoudige wijze van het wikkelen van spoelen is op een kunststof of metalen spoeldrager. Al naar gelang de specificaties, toleranties en kostentarget kunnen spoelen ‘wild’ gewikkeld worden of ‘in spoed’. Lees verder
