Horse Powertrain debuts its new high-efficiency amorphous motor

Horse Powertrain, an expert in innovative, low-emission powertrain systems, has made its global debut of its “Amorphous Motor” technology. This dedicated hybrid transmission motor achieves 98.2% efficiency, enabling a 1% reduction in whole-vehicle fuel consumption

First showcased at IAA Summit 2025, the Amorphous Motor uses amorphous steel, an alloy with high durability, strength, and magnetic permeability.

By utilising these properties of amorphous steel, Horse Powertrain has reduced the thickness of the steel layers required to make up a motor stator. As a result, the sheets used to assemble the Amorphous Motor are 0.025mm thick, one-tenth the thickness of steel used in traditional motors.

Using this conductive material, the Amorphous Motor’s losses to stator iron are reduced by 50% compared to equivalent designs, enabling the motor to achieve an efficiency of 98.2%, achieved while outputting 140kW at 360Nm.

These gains in efficiency mean that hybrids using the Amorphous Motor in their powertrains will see a 1% reduction in fuel and power consumption compared to those using existing motor designs, helping automotive OEMs provide a new generation of low-emission vehicle models.

Ingo Scholten, deputy chief technology officer of Horse Powertrain, said, “This latest innovation demonstrates Horse Powertrain’s continued commitment to research and development, providing suppliers and OEMs with the tools to raise the bar on when it comes to fuel economy and emissions performance. The Amorphous Motor is an ideal tool to power a new generation of high-efficiency range extended EVs, hybrids, and plug-in hybrids, ensuring these technologies continue to play a substantial role in automotive’s decarbonization journey.”
