Automotive Magnets: Precision Solutions for Electric and Intelligent Vehicles

Custom NdFeB magnets and ready-to-install magnetic assemblies for efficient, compact and reliably durable vehicle systems.

Automotive Engineering

Magnetic solutions for modern vehicle platforms

Permanent magnets perform numerous key functions in electrified vehicles – from traction drives, steering and braking systems to pumps, sensors and comfort applications. High power density, thermal stability and repeatable magnetic properties in a compact package are essential.

Spacemagnets Europe supports automotive projects from material and coating selection through magnetic-circuit optimization to quality-assured series supply. Geometry, magnetization and assembly concepts are matched to the load profile, temperature, installation space and lifetime requirements.

Typical magnet grades by application

The following ranges are technical guidance. Final grade selection is based on the operating point, geometry, temperature, corrosion exposure and required safety margin.

Vehicle systemTypical NdFeB rangeTechnical focus
Traction motorsN35UH–N52UH / N38EH–N42EHHigh coercivity, thermal stability and torque density
ABS and electric pumpsN38SH–N50SH / N38UH–N45UHDynamic response, compact design and reliable continuous operation

Sensors and ignition systemsN28UH–N42SHDefined field geometry and stable signal quality
LoudspeakersN35–N50 / N35M–N50MCompact magnetic circuits with high flux density

Maximum permissible operating temperature is not determined by the material alone. Magnet geometry, counter-field, coating, cooling and installation conditions also matter and are therefore verified for each project.

Engineering priorities for automotive magnets

Thermal and demagnetization margin

Magnetic operating-point design with sufficient reserve across the complete load and temperature profile.

Corrosion protection

Application-specific NiCuNi, epoxy, zinc or specialty coatings for moisture, salt and media exposure.

Low electrical losses

Segmentation, lamination and adapted geometries reduce eddy currents in high-speed systems.

Magnetic precision

Tight magnetization, angular-error and flux-distribution tolerances support low torque ripple.

Mechanically secure assemblies

Defined bonding, encapsulation and retention concepts secure magnets under vibration and high rotational speed.

Automotive quality

IATF 16949-oriented processes, traceability and project-specific inspection and documentation packages.
