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.

You may be asking why we’re advocating for the use of Ultra High-Temperature Sintering (UHTS) for powder metal components – As discussed previously, this revolutionary sintering process offers performance-enhancing benefits (such as lighter weight, reduced size, and higher fatigue strength) to a wide variety of applications (speed reducer sets, transmission components, ceiling fans, mobility applications, parking pawls, and more).
Nikola Tesla and Thomas Edison are names that resonate with innovation and discovery. Despite their inherent creativity, they pursued different paths to electrify the world. Edison was promoting DC, while Tesla was promoting AC. Ultimately, Tesla's theories on AC proved to be a preferred solution for electrification. As a consequence of this and his experience in electrical engineering, he set out to create a motor that ran solely on AC power without the need for brushes. Tesla’s aim was to develop a more reliable, efficient motor with precise control over its speed and torque – something no other motor had achieved before.
