Press Release

As electric vehicles and industrial automation continue to advance, electric motors are operating under increasingly demanding conditions. Higher voltages, faster rotational speeds, and more compact designs have significantly improved efficiency—but they have also introduced new reliability challenges.

Today, motor performance is no longer determined solely by mechanical design. Material selection has become a critical factor in ensuring long-term stability and reducing maintenance costs.

The Shift Toward 800V Platforms

The rapid adoption of 800V electric drive systems and SiC (Silicon Carbide) power devices enables faster charging, higher efficiency, and greater power density. However, these technologies also increase switching frequencies and shaft voltages, creating additional stress on bearings, insulation systems, and structural components.

Common challenges include:

Bearing electrical erosion caused by shaft voltage
Premature insulation aging due to partial discharge
Mechanical deformation under high-speed operation
Thermal cycling that shortens component lifespan

These issues cannot be solved by a single component. Instead, they require coordinated material solutions working together throughout the motor system.

Why Material Engineering Is Becoming Essential

Modern e-motors rely on multiple material systems to ensure reliable operation.

Conductive materials help safely discharge shaft voltage and protect bearings from electrical damage.

Electrical insulation materials maintain dielectric performance under high voltage and elevated temperatures.

Structural composite materials provide the strength needed for high-speed rotors while reducing overall weight.

Protective potting materials improve resistance to vibration, moisture, dust, and harsh operating environments.

By optimizing these materials as an integrated system, manufacturers can improve motor reliability, extend service life, and reduce unexpected downtime.
