PEEK/Nomex laminates for electric motors: performance, efficiency and reliability through innovative material combination

PEEK and Nomex laminates for electric motors: performance, efficiency and reliability through innovative material combination

The development of electric motors for electromobility and industry presents manufacturers with immense challenges. One of the biggest challenges is selecting materials that meet the high requirements for performance, efficiency and reliability. This is where the combination of PEEK (polyetheretherketone) and Nomex comes into play. By combining these two materials, laminates are created that offer a variety of advantages and thus represent an innovative solution for the electric motor industry.

Materials in focus: PEEK and Nomex

PEEK (polyetheretherketone)

PEEK is a high-performance plastic material known for its exceptional temperature resistance, electrical insulation and mechanical strength. These properties make PEEK an ideal material for applications in electric motors, where high temperatures and mechanical stresses prevail.

Nomex

Nomex paper, an aramid fiber material, is known for its good impregnating agent absorption. This property is particularly important in electric motors as it makes it easier to impregnate components, thus improving performance and reliability. By combining Nomex as an outer layer with PEEK as an inner layer, laminates are created that combine the advantages of both materials.

Flexible structures: diverse layer configurations for specific requirements

A key advantage of PEEK-Nomex laminates is the ability to create different structures and layer configurations to meet specific requirements. By combining PEEK and Nomex in different layers, electric motor manufacturers can achieve the optimal balance between performance, efficiency and reliability.

Examples of different structures and layer configurations:

• Nomex-PEEK-Nomex (NPN): An outer layer of Nomex with an inner layer of PEEK. This construction offers an optimal combination of impregnating agent absorption, mechanical strength and electrical insulation.
• PEEK-Nomex-PEEK (PNP): An outer layer of PEEK with an inner layer of Nomex. The advantage of this configuration is the Flexibility and other mechanical properties, since the impregnating agent absorption is limited by the inner Nomex layer.
• multi-layer structures (e.g. P/N/P/N): For applications with extremely high demands on performance, efficiency and reliability.

Properties of the laminates:

• Mechanical strength and stiffness: Optimized for the loads in electric motors.
• Electrical insulation performance: Ensures the safety and reliability of the engine.
• Thermal stability and thermal conductivity: Reduces heat generation and increases service life.
• flexibility and adaptability: Especially in configurations with inner Nomex layer.

Application in electric motors: advantages and practical examples

PEEK-Nomex laminates are used in various areas of electric motors, including:

• Insulation of windings and components: Improves electrical safety and reduces heat generation.
• housing and cover components: Provides mechanical strength and thermal stability.
• Other potential applications: Under development to further increase the performance and efficiency of electric motors.
