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 ...

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 ...

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.

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.

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 ...
