Magnetic Laminates
Magnetic Laminates
Tufflam MG267 is a special laminate based on epoxy resin and glass fabric with high content of iron powder for use as magnetic wedges in low and high-voltage rotating machines to improve electromagnetic performance. Tufflam MG267 is available in standard F class and H class versions and could be delivered in cut to size panels or machined slot wedges according to drawing.
SAM composites TUFFLAM MG267 MAGNETIC Epoxy Laminate is an innovative and high-performance material that offers a range of benefits for various applications. Some of the key advantages of this material include:
- Excellent magnetic conductivity: TUFFLAM MG267 is engineered with iron powder and an epoxy-based resin system, making it an exceptional conductor of magnetic energy. This property is particularly important for high-voltage induction motors, where the efficient transfer of magnetic energy is essential for reducing motor loss and noise.
- High mechanical strength: The glass cloth reinforcement in TUFFLAM MG267 provides exceptional mechanical strength, making it suitable for use in demanding applications. The material can withstand high levels of stress and strain, making it ideal for use in slot wedges for high-voltage induction motors, where durability and reliability are critical.
- Temperature control: TUFFLAM MG267 offers excellent thermal stability, making it resistant to temperature fluctuations and allowing for more efficient heat dissipation. This property is particularly important for high-voltage induction motors, where temperature control is critical for improving working efficiency and reducing energy consumption.
- Energy efficiency: By reducing motor loss and noise, TUFFLAM MG267 can help improve energy efficiency, thereby reducing energy consumption and associated costs.
Overall, TUFFLAM MG267 is an excellent choice for applications that require high magnetic conductivity, mechanical strength, temperature control, and energy efficiency. Whether you are designing high-voltage induction motors, transformers, or other electromagnetic devices, TUFFLAM MG267 can help you achieve optimal performance and reliability.
