Horse Powertrain Amorphous Motor Achieves 98.2% Efficiency with Ultra-Thin Steel Design

The Horse Powertrain Amorphous Motor was presented on March 5 as a next-generation hybrid transmission solution designed to significantly improve drivetrain efficiency. The technology introduces a stator built from amorphous steel, a highly conductive alloy that enables extremely thin laminated sheets and dramatically lowers energy losses during motor operation.

Ultra-Thin Amorphous Steel Stator Design

The new motor architecture uses stator laminations measuring only 0.025 mm in thickness. These sheets are approximately one-tenth the thickness of conventional electrical steel used in traditional electric motors. The reduction in material thickness improves magnetic performance while minimizing electrical losses.

Reduced Stator Iron Losses

By integrating amorphous steel laminations, the system reduces stator iron losses by nearly 50% compared with equivalent motor designs. This efficiency improvement allows the powertrain unit to operate with far lower energy dissipation during rotation and load changes.

Efficiency Gains for Hybrid Powertrains

The advanced material properties allow the motor to achieve an industry-leading efficiency of 98.2%. According to Horse Powertrain, the improvement can contribute to approximately a 1% reduction in overall vehicle fuel consumption when integrated into hybrid transmission systems.

Performance Output and Power Capability

The hybrid transmission motor maintains strong performance while delivering the efficiency gains. It produces a maximum output of 140 kW and peak torque of 360 Nm, ensuring the system can meet modern hybrid vehicle power requirements without compromising efficiency.

The combination of ultra-thin amorphous steel laminations and optimized electromagnetic design positions the technology as a significant advancement for high-efficiency hybrid propulsion systems.
