GTB Components

SMC materials are made of iron powder particles coated with an electrically insulating layer and can be formed into complex shapes by means of powder metallurgy, thereby allowing three-dimensional magnetic circuit design.

The intensifying electrification trend in the automotive industry along with calls for high-efficiency, low-cost industrial applications will drive the demand for energy- and cost-efficient electromagnetic components. Soft Magnetic Composite (SMC) materials play a fundamental role in this conversion, making it possible to manufacture more compact and cost-efficient motor and inductor solutions compared to using traditional designs.

The main benefits of SMC solutions for both motor design and production processes are:

• Compact design – both size and weight of the components can be reduced
• High performance – can meet the highest efficiency requirements
• Excellent cost efficiency – the compact designs require less material and enable simple net shaping production process with minimum waste and reduced need for subsequent operations.

Our Soft Magnetic Composites can be used in a wide range of different applications such as:

Automotive

• Traction motors
• Air conditioning compressors
• Pumps (cooling, oil, etc.)
• DC/DC converters
• On-vehicle chargers

Industrial

• Air conditioning compressors
• Ventilation fans
• Solar power
• Industrial motor drives
• Off-board battery charging

The SMC materials are developed for component manufacturing of electromagnetic applications, providing high performance and low losses. They are designed for efficient volume production at low cost, by utilising state-of-the-art technology. It is the 3D magnetic properties and the net shaping capabilities of the SMC materials that open up new opportunities to design compact, light and cost-efficient solutions.

Examples of how SMC materials can provide lower production costs:

• Size and weight reduction of components
• Reduction of the total number of parts in the final application
• Less need for machining
• Low scrap rate in manufacturing

Material Benefits:

• High resistivity
• High flux density
• Tight tolerances achievable
• Low core losses at High frequencies
• High permeability
• 3D flux paths
• Net shape capability
