CTI 2025 Highlight｜ YEESMA's Secret Sauce of Cost Reduction: Thermal !
At CTI 2025, one message came through loud and clear from OEMs and Tier 1s:
The industry is shifting its focus—from extreme performance and high speed to cost efficiency without compromise.
As explained by Dr. Philippe at CTI, cost reduction does not have to rely on pushing speed limits.
YEESMA achieves competitiveness through its electrically excited architecture and, more importantly, through advanced thermal management.
Rare‒Earth Free vs. Bulkier Motor & Expensive Inverter
To reduce the use of rare-earth magnets and achieve the same torque and power ratings, but the overall package becomes 30–40% larger and the inverter requires higher phase current.
In the end, it is not cheaper for the whole packaging.
As an axial flux EESM, YEESMA is more compact, requires lower phase current. Hence it reduces inverter costs. Put it simply: a cheaper motor and a cheaper inverter. That’s how we deliver significant reductions in overall BOM costs.
YEESMA wants to transform sustainability and cost
from a dream, to a vision, to a reality.
With over 35 years in the automotive and electric motor industry, Philippe Siad FARAH, our Co-founder of YEESMA, shares the why behind their journey:
A vision to remove rare-earth magnets from electric motors—not just to reduce costs, but to solve real issues of sustainability, supply chain risk, and environmental harm.
Challenges in electric motor industry: Balancing Performance, Cost,
and Sustainability
50% BOM cost reduction and 70% lower CO₂ emissions
That’s where 𝗬𝗘𝗘𝗦𝗠𝗔 comes in.
All while reducing dependence on rare-earth magnets that are expensive, environmentally damaging, and mostly sourced from a single country, creating serious supply chain risks. Let's explore how YEESMA address this issue by unique EESM-based axial flux technology and without rare-earth magnets.
Collaboration with MeltIngLab (Unimore)
From Concept to Reality ‒ Prototyping and Testing
"It has been the right convergence between academic research approaches and industrial pragmatism."
– Prof. Stefano Nuzzo
Together with MeltIngLab, this cooperation brings academic depth and industrial focus, making 𝗬𝗘𝗘𝗦𝗠𝗔’s technology more solid and closer to real-world applications. As Prof. Nuzzo highlighted, open-mindedness and practical feasibility are key in turning research into reality.
