In this work, the aforementioned loss components are evaluated for both hairpin and pull-in winding EESM variants. Moreover, a brief overview of the Zooming FEM analysis which is used to compute AC ...

The machine winds carbon fibers into lightweight yet ultrastrong tubes or rods up to 14-m long. A 50-m-long machine is also in the works. The winder has five axes of motion.

This paper presents an in-depth comparison of the overall efficiency and different loss components of high-speed traction electrically excited synchronous machines (EESMs), designed for hairpin and ...
