Alternating Current Photovoltaic Effect Enhanced Heat‐Resisting GaN Photodetector and Its Application in Highly Sensitive Wind Speed Sensing

open access: yesInterdisciplinary Materials, Volume 4, Issue 6, Page 850-859, November 2025.
Discovered in GaN Schottky junctions, the alternating current photovoltaic effect boosts ultraviolet photodetector responsivity and speed by two orders of magnitude. Heat treatment further enhances the performance. Integrated with a magnetic levitation structure, the device can work as a highly sensitive wind speed sensor. ABSTRACT Gallium nitride (GaN)

Research on the Influence of Multi‐Harmonic Magnetic Field on the Stability of the Radial Suspension Force and Electromagnetic Torque of Bearingless Motors

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
Bearingless motors can realise the rotor active suspension by the radial electromagnetic force, whereas the suspension force and torque ripple will increase the difficulty of motor control, which may lead to the stator and rotor collision and irreversible damage to the motor.

Design and Analysis of a Bearingless Permanent-Magnet Motor for Axial Blood Pump Applications

open access: yesIEEE Access, 2020
Because of their high power density and compact size, permanent-magnet (PM) motors have been commonly used to drive rotary blood pumps (RBPs), which are focused on the treatment of end-stage heart failure or as the bridge to a heart transplant.

Homopolar bearingless slice motor in temple design

open access: yes2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017
This work describes a concept of a magnetically levitated homopolar bearingless slice motor in temple design. The proposed setup consists of two oppositely magnetized permanent magnets on the rotor and stator and provides high axial stiffness. The fluctuation of the air gap field for torque generation is generated with a cross-shaped rotor iron ...

Co‐excitation control of a four‐degree‐of‐freedom magnetic bearing switched reluctance motor based on mathematical models

open access: yesIET Electric Power Applications, Volume 18, Issue 12, Page 1703-1718, December 2024.
The authors attempt to explore the co‐excitation control method of both radial magnetic bearing (RMB) and switched reluctance motor (SRM) by using a set of asymmetric power converters together in order to reduce the controller cost of conventional magnetic levitation motor systems.
