Abstract: The purpose of this paper is to study the design opportunities in high-speed toothless toroidal winding surface permanent magnet machine enabled by the implementation of silicon ...

Abstract: Due to the short end winding length of toroidal windings, it is conducive to improve the torque density of the machine. Therefore, this paper presents a new type of dual-rotor permanent ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...
