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.

Design and Analysis of Asymmetric Rotor Pole Type Bearingless Switched Reluctance Motor
CES Transactions on Electrical Machines and Systems, 2022 Bearingless switched reluctance motor (BSRM) not only combines the merits of bearingless motor (BM) and switched reluctance motor (SRM), but also decreases the vibration and acoustic noise of SRM, so it could be a strong candidate for high-speed driving ...

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 ...
