Bearingless switched reluctance motor [PDF]
, 2004 A switched reluctance motor has a stator with a first set of poles directed toward levitating a rotor horizontally within the stator. A disc shaped portion of a hybrid rotor is affected by the change in flux relative to the current provided at these ...

Electronics Letters, Volume 60, Issue 3, February 2024.This study analyzed the electromagnetic characteristics of the suspension force in the axial split‐phase bearingless switched reluctance motor to characterize the time‐varying suspension system accurately. The study elucidated the hinge relationship between the magnetic flux in the suspension system and the rotor position.

Fuzzy variable gain robust control of active magnetic bearings rigid rotor system
IET Electric Power Applications, Volume 18, Issue 1, Page 90-106, January 2024.First, the T‐S fuzzy model of four‐degree‐of‐freedom (4‐DOF) AMBs was established based on the 4‐DOF AMBs rigid rotor equivalent coupling model optimised by the μ‐gap metric. Then, the non‐dominated sorting genetic algorithm II (NSGA‐II) was used to find the relative optimal weight function value of H‐infinity robust controller when AMBs system was at ...
