NORWE
NORWE is an European Manufacturer of Standard and Custom designed thermoplastic Bobbins for Ferrite Cores & Metric Transformer Laminations, Components for SMD and Planar Technology, Potting Boxes for Toroidal Cores, Safety-Class Bobbins and Accessories.
The extensive standard range of coil formers currently includes around 25,000 different items and is supplemented by a large number of special designs for a wide range of applications. In addition, NORWE also develops and manufactures – and this is the special know-how of the specialist manufacturer from Bergneustadt – very individual electrical and electronic components according to customer specifications.
With 3D printing, it is possible to build three-dimensional components in one operation using a printer without the tools or molded parts that would otherwise be required. Depending on the process and application, detailed, immediately usable components are created for prototypes or small series.
The greatest possible protection of people and the environment has always been a high priority at NORWE. This is documented by a certified environmental management system, among other things with the aim of increasing the introduction of plastics with halogen-free flame retardant systems.
Bobbins for making transformers are essential components in the construction of electrical transformers. They serve as the structural framework that holds and organizes the wire windings and other essential components of the transformer. Here are some key points about bobbins used in transformer manufacturing:
NORWE Catalog
-
Structural Support: Transformer bobbins provide structural support for the internal components of the transformer, including the primary and secondary windings, core, and insulation.
-
Material: Bobbins are typically made from insulating materials, such as thermosetting plastics or phenolic resins. These materials offer electrical insulation to prevent short circuits and ensure the safety of the transformer.
-
Design and Shape: The design and shape of the bobbin can vary depending on the specific requirements of the transformer. Some bobbins are cylindrical, while others may have custom shapes to accommodate the specific winding pattern.
-
Core Mounting: The transformer core, which is often made of laminated iron or ferrite, is mounted on or within the bobbin. The core plays a crucial role in the transformer's operation by providing a path for magnetic flux.
-
Wire Winding: The primary and secondary coils of wire are wound around the bobbin. The bobbin's design ensures that the winding is neat, organized, and spaced properly to minimize interference and maximize efficiency.
-
Insulation: Transformers operate at different voltage levels, and it's essential to prevent electrical breakdown between the windings. The bobbin material provides electrical insulation between the primary and secondary coils.
-
Mounting and Termination: Bobbins often have mounting holes or brackets for secure placement within the transformer assembly. They may also have terminals or pins for connecting to external circuits.
-
Customization: Transformer bobbins can be customized to meet the specific requirements of the transformer, such as the number of turns, wire size, and the desired electrical characteristics.
-
Quality and Tolerances: High-quality bobbins are essential for maintaining the integrity of the transformer. Precision manufacturing and tight tolerances are necessary to ensure consistent performance and efficiency.
-
Safety and Standards: Transformers, including the bobbins used in their construction, need to comply with safety and performance standards, depending on their intended application.
Transformers play a crucial role in electrical systems, stepping voltage up or down as needed. The bobbins used in their construction are a fundamental component, providing structural support, electrical insulation, and organization for the critical internal components. Transformer manufacturers carefully select and design bobbins to meet the specific electrical and mechanical requirements of the transformers they produce.
