Engineering Solutions Motor Design

Windings has been a trusted supplier of custom electric motors, generators, and electromagnetic components to the aerospace industry for over 50 years. Founded in 1965 to produce AC synchro motors used in commercial and military avionics, Windings is well versed in the design and regulatory requirements driven by the unique environmental hazards and performance challenges associated with air and space operations.

Our view on intellectual property gives Windings customers the flexibility they need to prevent supply chain issues related to single sourcing and the ability to protect business assets that are core to their business. Intellectual Property retention is recommended for customers who need assistance developing their projects’ design and want to safeguard their project’s information and supply chain.


With more than 165 years of combined engineering experience and access to the latest design tools, Windings’ engineering team offers a host of professional engineering services to complement and extend your internal capabilities. Services include analysis of electric motors and solution design feedback, part design analysis and simulationprototype testing, and reverse engineering of legacy designs.

The electric motor engineering experts at Windings help our clients to:

  • Solve challenging or complex issues relating to critical applications
  • Achieve “stretch goals” for performance, reliability, or cost
  • Compress tight new product development schedules
  • Supply rapid prototypes for proof-of-concept testing and design iteration

Windings’ engineers are supported by engineering technicians and documentation specialists that are skilled both mechanically and electrically to provide packaging for our client designs, as well as technical documentation for our manufacturing team. With Windings’ 50-year history of manufacturing electric motors for aerospace applications, combined with our engineering team’s skills and experience, you can be assured that your project will transition smoothly and seamlessly from engineering and prototyping to pilot and full-rate production. 

Windings’ Quality Management System (QMS) Certifications include ISO 9001:2015 / AS9100-D, ITAR Registration, RoHS 2002/95/EC, and NADCAP Accreditation. US domestic production facilities and capabilities are located in New Ulm, MN for prototyping, pilot production, and Low Rate Initial Production (LRIP). As production quantities increase Windings offers a seamless transition to their certified production facility located in Mexico. The highest standards in concept development, engineering, material management, and part production are maintained while achieving a global presence in the industry.
