UQM Technologies was granted a U.S. patent for a new permanent-magnet electric motor design that uses non-rare earth magnets.

According to the company, performance of the new motor is similar to current motors with rare earth magnets.

"This new design provides a similar level of performance to UQM’s current design, and once the development is completed will allow UQM the flexibility to choose between these systems depending on projected magnet costs into the future.

United States Patent Number 8,928,198 was issued and assigned to UQM Technologies on January 6, 2015. The patent covers the unique magnet geometry and the method of manufacturing the motor."

Eric R. Ridenour, President and Chief Executive Officer of UQM Technologies, Inc. stated:

“The patented technology that we’ve developed provides a viable option to existing rare-earth motor technology, limiting exposure for us and our customers to the price and political volatilities of rare-earth magnets. We are now in the prototype stage and the first samples are meeting our objectives, providing us with the validation to move into the next phase of development.”

UQM got a $4 million Department of Energy (DOE) Advanced Research and Development Grant for this project.
