Dana LLC is pleased to announce the culmination of a collaboration with Bergstrom Inc. to develop a reliable, cost-effective, and highly capable brushless DC (BLDC) motor controller that will be incorporated into Bergstrom’s class-leading commercial and specialty vehicle climate control systems.

Dana was responsible for the design of the custom control electronics, which will be integrated with a Bergstrom motor in a final assembly that Bergstrom will manufacture for its customers.

“Dana’s hardware and software engineers worked closely with the Bergstrom team to understand the product requirements and to ensure the final assembly Bergstrom will produce meets all of the needs of its customers” said Dr. Walter Lucking, CEO of Dana. “Working on this project has been a great experience for our team and we’re looking forward to a close partnership with Bergstrom in the future.”

The controller has been designed to operate in 12V and 24V systems and incorporates a variety of different control signal inputs, covering the spectrum of Bergstrom’s vehicle customer’s needs.  It also contains self- diagnostic capability to provide superior reliability in a sensor-less design. The control electronics have been fully tested and passed some of the most rigorous electro-magnetic compatibility (EMC) criteria possible.

“Having a partner like Dana that really understands the intricacies of control electronics design for vehicle applications is invaluable in supporting Bergstrom’s product development efforts and keeping us at the forefront of technology in the market for vehicle climate systems.” said Bjorn Hansson, Mechatronics Chief Engineer for Bergstrom.

Bergstrom’s system incorporating the Dana designed controller goes into volume production in 2016.  This custom BLDC design adds to a growing portion of Dana’s business providing custom electronics solutions for customers in multiple markets.  Other recent applications include a UAV engine controller, a specialty injector driver module, and a hybrid vehicle supervisory control module.



Dana LLC has been in the United States since 1990. The OpenECU product family (Model-Based development Software Platform) is Dana’s signature product family and by 2019 there were more than 40,000 OpenECU based ECUs on the road in production vehicle applications.
