Super‐spiral sliding mode controller design for single‐winding bearingless switched reluctance motor
IET Electric Power Applications, Volume 16, Issue 12, Page 1492-1501, December 2022., 2022 Abstract The strong coupling effect between the torque system and the suspension system of the single‐winding bearingless switched reluctance motor (SWBSRM) would result in continuous interference to the system and bring difficulties to the design of the control system.

IET Power Electronics, Volume 15, Issue 13, Page 1249-1263, 14 October 2022., 2022 Abstract The performance of flywheel battery is affected by the vibration and friction of traditional mechanical bearing. A novel kind of bearingless brushless direct current machine (BBLDCM) with the hybrid capabilities of electrical machine and suspension is suitable for flywheel battery which reduces the losses and improves the power quality.

IET Electric Power Applications, Volume 16, Issue 8, Page 912-925, August 2022., 2022 Abstract The doubly fed induction generator is commonly used in commercial wind turbines because of its simplicity and robustness; it is a wound rotor induction machine. It has a relatively small airgap which makes it more vulnerable to unbalanced magnetic pull.

Mathematical model of a novel 12/14 conical bearingless switched reluctance motor
Energy Reports, 2022 Aiming at the defect that the traditional bearingless switched reluctance motor cannot control the axial suspension force, so that the rotor cannot achieve five-degree-of-freedom suspension by itself, this study presents an innovative 12/14 conical ...

Design and analysis of double 6/3 transverse flux bearingless switched reluctance motor
Electronics Letters, Volume 58, Issue 15, Page 573-575, July 2022., 2022 Abstract A novel dual 6/3 Transverse Flux Bearingless Switched Reluctance Motor is proposed to solve the coupling problem between torque and suspension of conventional Switched Reluctance Motor. The working principle is introduced in detail, the motor is modelled by ANSYS, and the accurate mathematical model of the suspension force is deduced and ...

IET Electric Power Applications, Volume 16, Issue 3, Page 328-349, March 2022., 2022 Abstract Due to the dual air‐gap topology of the direct‐drive permanent magnet motor with inner enhance force (IEF‐DDPMM), the radial EM exciting force generated in the inner and outer air gaps when the rotor is eccentric will act on the same rotor, and the unbalanced magnetic pull (UMP) on the rotor will reduce the fatigue life of the rotor structure ...
