I just saw a motor using 0.025 mm steel
That’s 10x thinner than usual.
Can push motor efficiency to 98.2%.
Horse Powertrain unveiled a new motor technology.
It uses ultra-thin amorphous steel layers.
Amorphous steel lacks a crystal structure.
So magnetic losses reduce significantly.
The stator is the motor’s stationary core.
Magnetic fields rotate inside this structure.
Traditional steel sheets are much thicker.
This design uses just 0.025 mm sheets.
Iron loss means wasted magnetic energy.
Losses drop nearly fifty percent here. ⚡
Efficiency now reaches an impressive 98.2%.
Peak output reaches 140 kW and 360 Nm.
Even hybrids gain around one percent efficiency.
Small gains matter in powertrain engineering. 🔧
Would amorphous stators reshape future EV motor design?
