Yokeless/Yoked Electrically Excited Synchronous
Machine, YEESMA
YEESMA is a groundbreaking motor technology that eliminates the need for rare-earth magnets, significantly reducing material costs and environmental impact.
-45% Bill of Material
High Potential, Cost-Effective
No need for rare-earth magnet
—cutting costs without cutting performance.
-50% CO2 emissions
Greener by Design
Less use of copper and no rare-earth magnet
— lower CO₂ emissions and a stronger alignment
with sustainability goals.
-25% Volume
Made for Mass Production.
Simplified structure = faster, easier assembly.
Power Without Rare Earths. Progress Without Limits.
At YEESMA, we’re redefining electric mobility with motors that are high-performance, low-emission, and free from rare-earth dependencies.
