Discuss your applicationEnergy & Power Components.
From generators and motors to power electronics and structural components, our product families support multiple stages of energy systems — including wind, hydro, solar tracking, conversion and storage.
Generation. Conversion. Supporting Hardware.
Generator Magnets
Grades selected around load, temperature and environment.
Power Magnetics
Magnetic cores for power-conversion requirements.
Metal Enclosures
Housing, mounting and sealing interfaces for power equipment.
Mechanical Components
Shaft and mechanical interfaces with agreed machining and inspection.
Production route, manufacturing responsibility, available documentation and acceptance criteria are confirmed for the particular product and order.
Typical Applications
Across the energy system:
| Application | Typical Material | What Matters |
|---|---|---|
| Wind turbine generators | NdFeB N40SH–N48SH blocks | High Hc, corrosion protection |
| Hydro generators | NdFeB segments, SmCo options | Sealed, long-life operation |
| Solar tracker drives | Ferrite + NdFeB motor magnets | Outdoor durability, cost |
| Power electronics / converters | Soft magnetic cores, LTCC | Core loss, frequency stability |
| Magnetic couplings (pumps) | SmCo + NdFeB couplings | Non-contact torque transfer; containment and maintenance requirements reviewed for the assembly |
| Energy storage / BMS | Sensor magnets, die-cast housings | Consistency at volume |
What We Supply to Energy & Power OEMs
- ✓High-coercivity generator grades — N40SH through N48SH with proven demagnetization margins for direct-drive and hybrid generator designs
- ✓Heavy-duty corrosion protection — multi-layer Ni-Cu-Ni plus epoxy, validated by salt-spray testing to 3000 hours for offshore and coastal sites
- ✓Magnet segmentation — we help optimize magnet block segmentation to balance eddy-current losses, assembly, and cost
- ✓Large block capability — generator magnet blocks to 70 kg+ with magnetization and assembly services
- ✓Soft magnetic cores for power electronics — materials for inductors, chokes and converters supporting energy conversion stages
- ✓Volume and consistency — production capacity, material sourcing and release quantities are reviewed against the program forecast
