Development & Simulation
Efficient product development through modern simulation technology
We support you right from the design phase: we use 2D/3D FEM tools to develop and simulate your inductive components precisely according to electrical, thermal and mechanical criteria. This reduces development costs and accelerates your time-to-market.
X-ray analysis
X-ray inspection for maximum process reliability
We use high-resolution X-ray analysis for quality assurance. This allows us to check invisible solder joints, layer build-up and potting defects - an essential step for safety-critical applications in medicine, aviation and industry.
Thermal & electrical calculation according to EN/UL standards
Safe design in accordance with international standards
Our developers calculate your winding material in accordance with EN 61558, UL 5085, IEC 60076 and other standards - both in terms of current carrying capacity, temperature behavior and clearances/creepage distances. This means you receive tested components with a standard-compliant design.
UL insulation system
UL-listed insulation system - tested and documented
With our in-house insulation system (UL File E346192, Class F), we can supply you with UL-compliant components quickly and reliably - without the need for lengthy individual approvals. Ideal for export to the USA and Canada.
Material selection according to UL 94 / IEC 60216 / 60085
Material expertise for safety and durability
We select materials in accordance with international standards such as UL 94 (flammability), IEC 60216 (thermal ageing) and IEC 60085 (temperature classes). In this way, we guarantee durable, approval-compliant products for industrial and safety-critical applications.
Vacuum impregnation & potting (IP protection types)
Reliable protection through vacuum impregnation and potting
We offer vacuum impregnation and fully encapsulated assemblies - tailored to your protection requirements (e.g. IP68). Whether climatic influences, moisture or vibrations - we make your components robust and durable.
Test protocols & validation
Measurable quality - documented & traceable
Each finished component can be supplied with test reports, electrical measurements and validation reports on request. This creates trust and reduces your QA workload.
Prototyping & series transfer
From prototype to series production - flexible and fast
We manufacture individual samples and support you through to series production - including design optimization, production approval and scaling. Ideal for development departments and pilot customer projects.
EMC-compliant design development
Interference-free systems thanks to EMC-compliant design
We support you in the development of EMC-compliant solutions - from shielding concepts and current-compensated chokes to conductive potting. So that your products reliably comply with the required EMC limits.
From simulation to series production - everything from a single source
We are Rotima AG and support our customers in the development and production of customized inductors. Our aim is to supply technically sophisticated components that impress in terms of performance, quality and compliance with standards.
We rely on modern simulation technologies right from the design phase. Using precise 2D and 3D FEM analyses, we develop components that reliably meet electrical, thermal and mechanical requirements. This approach enables us to reduce development costs and accelerate the transition from idea to series production.
Another focus is on safe design in accordance with international standards. Our developers take into account relevant standards such as EN 61558, UL 5085 or IEC 60076, resulting in solutions that can be used worldwide and meet the highest safety requirements.
Thanks to our material expertise and proven processes such as vacuum impregnation or encapsulation, we reliably protect the components from external influences. In addition, test protocols and validations ensure consistently high quality.
With this comprehensive approach, we create the basis for reliable and durable inductors that are used in demanding applications such as medical technology, industrial automation and aviation.

Precise development of customized inductors through simulation and conformity to standards
The development of inductive components requires the utmost care, as electrical, thermal and mechanical factors must be precisely coordinated. At Rotima AG, we use modern FEM simulations to precisely design coils, chokes and transformers. We can test different load scenarios as early as the design phase, thereby increasing subsequent reliability.
A major advantage of this approach is the early validation of the required performance parameters. Customer-specific transformers or coils for EMC-critical applications are not only calculated, but also designed in accordance with applicable standards such as EN 61558 or UL 5085. In this way, we ensure that every winding material meets international safety and quality requirements.
For purchasers, this means calculable costs and a faster time to market. Engineers receive components that are tailored to their applications and can be integrated into systems without time-consuming reworking. This close integration of simulation and conformity to standards gives us a decisive competitive advantage.

Production with quality assurance and documented process reliability
The production of customized inductors involves far more than just winding copper wire. We rely on end-to-end quality assurance, from material selection to final testing. Using methods such as X-ray analysis, we can reliably detect invisible solder joints or layer defects. We also carry out electrical and thermal tests in accordance with international standards to ensure a high level of operational safety.
Our manufacturing processes also include vacuum impregnation and potting processes up to IP68 protection classes. This makes coils and transformers resistant to moisture, temperature fluctuations and vibrations. On request, we can supply each component with test reports and detailed measurements. This provides purchasers with transparent documentation, while developers can take advantage of the complete traceability of product quality.
This consistent focus on quality and safety makes our wound products a reliable choice for industries such as medical technology, aviation and industrial automation. By combining manufacturing expertise, documented validation and standard-compliant design, we safeguard our customers' investments in the long term.
