C-CORE S

types and shapes of C-cores

C-cores come in various types and shapes. For example, they include:
-One-Step: Uses a single strip width.
-Cruciform: Consists of multiple steps with different widths.
-Single-Phase: Ideal for single-phase applications.
-Three-Phase: Suitable for three-phase systems.
-Shapes: Available in circular, oval, or rectangular forms.

Factors Influencing C-core Properties Several factors impact the properties of C-cores. For instance:

-Geometry: The specific shape of the core is crucial.
-Air Gap: The size of the gap between cut surfaces affects performance.
-Steel Quality: The quality of CRGO steel used also plays a significant role.

Measurement of C-cores

To ensure precise measurement of magnetic properties, we utilize specialized instruments. Moreover, we conduct 100% testing on all our cores. This thorough process involves not only monitoring but also recording measurements. Specifically, we measure:
-Ntensity of the Magnetic Field (Heff): Given in A/m.
-Magnetic Induction (Bmax): Expressed in Tesla (T).
-Core Losses (P): Measured in watts (W).
-Amplitude Permeability: Evaluated to assess overall performance.

Production of Divided C-cores

When producing C-cores, we wind a strip of CRGO steel onto a rotating mandrel. After winding and applying epoxy resin, we then cut the core into several pieces. Notably, the quality of the cut surfaces is critical to the core’s final functionality. Specifically:
-Common Quality: Up to 30 μm, categorized as TYPE "A".
-Grinding cutted surfaces: TYPE "C"

Specifications and Guarantees

For cores wound from 0.35 mm thick tape (grade N), we guarantee:
-Maximum Allowable Measuring Losses: Bmax = 1.5 T at 50 Hz.
-Specific Loss Values: 2.5 W/kg, in accordance with DIN 41309 and IEC 329 standards.
Conversely, for cores made from 0.10 mm thick tape, we guarantee:
-Specific Losses: Up to 15 W/kg.
-Magnetic Induction: Bmax = 1.5 T at 400 Hz.

Furthermore, we provide measurement certificates for magnetic properties upon request.

In Conclusion

In summary, our C-cores combine high-quality materials with precise measurements to ensure reliability and efficiency. By using advanced technologies and maintaining stringent quality controls, we deliver products that meet and exceed industry standards.
