Electric motor design is about more than just reducing cost -- it’s about the chance to get innovative and exceed performance expectations.
If you’re already experimenting with new electric motor solutions that are a little "different,” consider incorporating powder metallurgy (PM) into your plan. Whether you’re looking for electric motor efficiency or cost reduction, chances are a PM solution exists.
Use this hub as a resource for understanding the advantages of powder metallurgy for motor applications vs. competing technologies like electrical steel laminations. Below you can learn more about the untapped potential powder metallurgy holds for motor makers -- and how you can use it to push the boundaries of your design.
Using powder metal parts to cut costs is nothing new. Using powder metal components to further the “electrification” of transportation and other electromagnetic applications is the new frontier for driving performance and cost-efficiency to new heights.
In the case of transportation, these opportunities go far beyond the traditional automobile. Powder metallurgy processes and materials are seeing more use in:
Powder metal materials and processes can optimize both AC and DC motors -- everything from axial flux motors to magnetic torque tunnels. Basically, anything that needs to be small and efficient needs to include metal powder parts.
In the race to innovate, electric motor designers no longer need a “good enough” solution, they need a great solution. Powder metallurgy’s benefits go hand in hand with cutting-edge design.

Choosing powder metallurgy materials means you must consider a handful of different factors, including desired part performance, market availability, and more. While all of these factors play a role in the decision-making process, many manufacturers only want to ask one question: “How much does it cost?”
When it comes to electric motor materials, there’s not much to choose from.
The two big contenders right now are electrical steel laminations and soft magnetic composites (SMCs). While they both have their benefits, they also have some problems, including:
