Collaboration Spotlight: Modal Motors + MPP Driving Next-Gen Electrification

At MPP, we believe the future of electrification is built on strong partnerships. Our collaboration with Modal Motors combines their patent-pending motor architecture with our advanced soft magnetic composites (SMCs) to deliver higher torque density, rare-earth-optional designs, and scalable U.S. manufacturing. Together, we’re unlocking new performance and efficiency for next-generation mobility systems.

  • Hybrid Stator Stack: Laminations for high-B 2D paths + SMCs for 3D flux, loss reduction, and design flexibility.
  • Rare-Earth Optional: Architecture can eliminate permanent magnets and use aluminum coil windings.
  • MPP SMC Stator Tips: SMC stator cap + stator pole wing tip (Samoloy® 700 3P) enabling 3D flux handling.
  • Domestic & Scalable: Michigan manufacturing; cell-based robotic assembly; U.S. supply chain ready.

Why This Collaboration Matters

Modal Motors’ patent-pending architecture is engineered to harness all magnetic flux inside the motor, rgeting the highest torque density and full-speed-range efficiency. By eliminating back irons and yokes, major loss sources in conventional
designs—the platform boosts efficiency and enables materials flexibility, including rare-earth-free options and aluminum coils.

MPP’s Role: Advanced SMC Stator Tips

MPP supplies soft magnetic composite (SMC) stator tips—specifically the SMC stator cap and stator pole wing tip manufactured using Samoloy® 700 3P. SMCs enable 3D flux, disrupt eddy currents, and unlock geometric flexibility where laminations are less efficient.

Hybrid Stator Innovation

  • Laminations: Carry very high B-fields (≥ 2.0 T) in simple 2D flux paths.
  • SMCs: Handle 3D flux, reduce losses, and enable complex geometries.
  • Together: Leverage both materials for higher efficiency and smarter magnetic circuit design.

Built for U.S. Manufacturing

The Modal architecture supports cell-based robotic assembly with low capital and low/no-touch labor, scalable as volumes and motor sizes increase. Combined with MPP’s seven U.S. operations, customers gain a resilient, domestic supply chain from
materials through assembly.

Meet us at The Battery Show 

This collaboration will be highlighted at The Battery Show North America, where attendees can explore Modal’s innovative motor design and MPP’s enabling stator technology. The companies will jointly showcase their work on the exhibition floor with Modal’s design featured at Veolectra Booth 2450 and MPP’s full suite of electrification solutions at Booth 822.
