Client Background:

The client is a global leader in advanced materials and core technologies for electric motors and generators.

Challenges:

Comparing multiple competing material technologies.
Mapping a wide landscape of suppliers and technology developers.
Balancing performance with manufacturability, scalability, and commercial readiness.

Engagement Objective:

The client wanted to understand the competitive and adjacent supplier landscape for amorphous and nanocrystalline motor-core materials, while benchmarking these technologies against advanced electrical steels and soft magnetic composites.

Approach:

The team at Stellarix engaged in:

Identifying key competitors and enabling players across soft magnetic materials for EV, aerospace, and UAV applications.
Mapping the competitive landscape of amorphous, nanocrystalline, and adjacent substitute materials, including their target frequency ranges and application focus areas.
Evaluating material suitability across the 100 Hz-2 kHz electrical frequency band, with emphasis on high-frequency performance in the 400 Hz-2 kHz range.

Final outputs included a PPT and a dataset (Excel) covering competitors and enablers, benchmarking across technical and commercial parameters, and profiling top players by technology, materials, applications, etc.

Solution Offered:

Competitor Assessment

Identified soft magnetic material suppliers and ecosystem enablers, including Vacuumschmelze (materials supplier) and Sumitomo Electric Industries (motor OEM), serving electric vehicle, aerospace, and UAV applications.

Material Assessment

We identified key classes of soft magnetic materials, including amorphous alloys, nanocrystalline materials, advanced electrical steels, and soft magnetic composites (SMCs). Their suitability was evaluated across a range of electrical frequencies. For example, Vacuumschmelze’s 40–50% nickel-iron alloys demonstrate frequency-dependent core loss behavior, with iron loss values such as 0.30 W/kg at 1 T and 50 Hz.

Competitor Benchmarking & Mapping

Identified material suppliers were mapped across key technical and commercial parameters. For example, Vacuumschmelze’s portfolio includes nanocrystalline materials such as 40–50% nickel–iron alloys, which are applicable in laminated rotor and stator stacks used in high-efficiency electrical machines.

Future Direction & Solutions

Nanocrystalline materials offer the best combination of technical properties among soft magnetic materials for motor-core applications.

Client Impact:

The client gained a clear, comprehensive understanding of key suppliers and competing solutions, with evidence-based comparisons supporting material selection. The engagement also provided a clear direction for future motor-core materials.
