Horse Powertrain has unveiled a new hybrid transmission motor that uses amorphous steel in the stator and, the company says, reaches 98.2% efficiency while delivering 140 kW and 360 Nm.

The company says the motor’s stator uses amorphous steel alloy layers just 0.025 mm thick—about one tenth the thickness of steel used in conventional motors. According to Horse, that cuts stator iron losses by 50% versus equivalent designs, which is the main reason the unit reaches its claimed efficiency figure.

Horse is positioning the motor for hybrids, plug-in hybrids, and range-extended EVs. The company says the efficiency gain can translate into a 1% reduction in whole-vehicle fuel and power consumption compared with existing motor designs.

“This latest innovation demonstrates Horse Powertrain’s continued commitment to research and development,” said deputy CTO Ingo Scholten. He called the motor “an ideal tool” for a new generation of high-efficiency hybrids and range-extended EVs.
