UQM Technologies Granted Patent on Electric Vehicle Motor Design that Allows the Use of Non-Rare Earth Magnets.
UQM Technologies has been granted a U.S. patent for its electric and hybrid electric vehicle motor design using non-rare earth magnets. The majority of electric and hybrid electric vehicles produced today use permanent magnet motors with rare-earth magnet materials. 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.
“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,” said Eric R. Ridenour, President and Chief Executive Officer of UQM Technologies, Inc. “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.”
Implementation of this patented technology is part of a $4M Department of Energy (DOE) Advanced Research and Development Grant previously awarded to UQM for the development of non-rare earth magnet electric motors for use in electric and hybrid electric vehicles.
UQM Technologies is a developer and manufacturer of power-dense, high-efficiency electric motors, generators and power electronic controllers for the commercial truck, bus, automotive, marine, military and industrial markets. A major emphasis for UQM is developing propulsion systems for electric, hybrid electric, plug-in hybrid electric and fuel cell electric vehicles. UQM is TS 16949 certified and located in Longmont, Colorado. (1/20/15)
