Mastering Litz Wire: Winding and Welding Techniques for Enhanced Performance

This presentation commences with an introduction to Litz wire by Mr. Benjamin Braggins. He will explore various types of Litz wire, discuss VDE and UL certifications, cover coating options such as serving and taping, and provide valuable insights into the best design practices for electric motors and magnetic components. Mr. Rajasekhara will continue highlighting the main obstacles in winding and welding processes that involve litz wire and how they can be overcome. From how to control tension to get perfect layering despite the variable morphology of the wire, how to avoid wire untwisting, up to how to get clean and solid wire/terminal welding points with wire with high thermal class and composed of many tiny, twisted wires.
