Powering the Future of Electrification
Metal Powder Products (MPP) has been awarded a United States patent for an induction rotor design that eliminates the use of rare earth magnets. This milestone reinforces our position as a leader in advanced powder metallurgy and electrification solutions, helping customers achieve higher efficiency, stronger supply chains, and more sustainable designs.
Why it Matters:
Electrification demands more from every component. Motors must deliver higher power density, operate more efficiently, and be sourced sustainably. At the same time, global supply chains for rare earth magnets remain unpredictable.
Our patented induction rotor addresses these challenges head-on, giving customers:
Supply chain confidence – Reduced reliance on rare earths through U.S.-sourced materials
Compact efficiency – High torque and power density without added weight
Sustainable performance – Near-net-shape manufacturing that reduces scrap and lowers total cost
What are Soft Magnetic Composites (SMCs)?
At the core of this design are Soft Magnetic Composites (SMCs) — engineered powder metal materials coated with an insulating layer. Unlike traditional laminations, SMCs carry magnetic flux in three dimensions, enabling designs not possible before
SMC Advantages:
3D flux capability → reduces core losses
High-frequency performance (10,000 Hz and beyond)
Near-net-shape production → lighter parts, minimal scrap
Design flexibility for compact, efficient architecture
SMCs unlock the ability to design motors that are smaller, lighter, and more efficient — a perfect fit for electrification where every millimeter and every watt matters.
Why Copper Matters
Our rotor is pressed from copper using powder metallurgy — a deliberate choice that brings measurable benefits. Copper provides superior conductivity and efficiency compared to alternatives, translating into:
- Higher torque output and usable power
- Lower energy loss and improved thermal behavior
- Durability for long service life in demanding duty cycles
For customers, this means motors that run cooler, last longer, and deliver more power per unit of energy.
Applications Across Markets
This technology is optimized for axial flux motor systems, but its value extends far beyond one configuration.
- Transportation: EV traction motors, auxiliary drives, pumps, onboard power generation
- Industrial: Cooling fans, pump motors, distributed energy systems
- Commercial: HVAC systems, appliances, energy storage
Wherever electrification is driving change, MPP’s patented induction rotor offers more performance with fewer compromises.
