Journal of Electrical Engineering & Technology, 2020 In this paper, a 3D analytical model of permanent magnet (PM) and electromagnetic hybrid Halbach array electrodynamic suspension (EDS) system for a conductive plate is presented. When the hybrid Halbach array moves to cut the conductive plate, the 3D eddy current forces are derived using the second-order vector potential (SOVP) based on y-component of ...

2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021 This paper investigates a bearingless motor with full passive suspension. The axial direction is stabilized by an electrodynamic force generated by a specific coil configuration called a figure-eight coil. Radial directions and tilting angles are stabilized by passive permanent magnet bearings.
