A 5‐degrees of freedom hybrid excitation bearingless motor for vehicle flywheel battery

Electronics Letters, 2021
To deal with the restriction of vehicle space on a flywheel battery, a 5‐degrees of freedom (DOF) hybrid excitation bearingless motor (HEBM) was proposed. The 5‐DOF suspension force required for the flywheel battery is provided by HEBM.

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

IET Electric Power Applications
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 ...

Analysis and weakening of radial electromagnetic forces in high‐speed permanent magnet motors with external rotors based on shape functions

IET Electric Power Applications, Volume 17, Issue 5, Page 656-669, May 2023., 2023
Abstract In this paper, a strategy of integrating direct‐drive turbine compressors with high‐speed permanent magnet external rotor motors is used to improve the problems of large footprint, low efficiency and high maintenance costs. The rotor of the motor will vibrate under the action of radial electromagnetic force when rotating, and under the action ...

New technical concept for alternating tangential flow filtration in biotechnological cell separation processes

Biotechnology Progress, Volume 39, Issue 2, March/April 2023., 2023
Abstract Robust cell retention devices are key to successful cell culture perfusion. Currently, tangential flow filtration (TFF) and alternating tangential flow filtration (ATF) are most commonly used for this purpose. TFF, however, suffers from poor fouling mitigation, which leads to high filtration resistance and product retention, and ATF suffers ...

Qualification of a Single‐Use Disk Stack Separator for Cell Separation in Mammalian Cell‐Based Antibody Production

Chemie Ingenieur Technik, Volume 94, Issue 12, Page 1936-1943, December 2022., 2022
The cell separation process is one of the key elements in biopharmaceutical productions. In the last years, some new devices were launched by different manufacturers. In this work, the novel single‐use disk stack separator kytero 500 from GEA was successfully used for the separation of antibody producing Chinese hamster ovary cells. Abstract Single‐use

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.

Mathematical modelling and control of bearingless brushless direct current machine with motor and generator double modes for flywheel battery

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.
