High-efficiency brushless rotor excitation (maintenance-free)
Reduces friction, wear, and mechanical failure risks. Optimized for high-speed e-motors, ensuring long-lasting performance and reliability.
Better thermal stability than PSM
Electromagnets less sensitive to high temperatures, providing enhanced durability and consistent operation in demanding thermal conditions.
Inherently rare-earth-free design
Sustainable and cost-effective, reducing reliance on rare earth materials while ensuring robust supply chain stability and improved thermal management.
Cost savings
The EESM offers larger possibilities of cost saving on the bill of materials (BOM). In fact, the additional cost of the rotor excitation system becomes relatively small in comparison to the larger mass of magnets that can be saved.
