Role of the Two Flagellar Stators in Swimming Motility of Pseudomonas putida
MBio, 2022 In the soil bacterium Pseudomonas putida, the motor torque for flagellar rotation is generated by the two stators MotAB and MotCD. Here, we construct mutant strains in which one or both stators are knocked out and investigate their swimming motility in ...

Optimization of pre-swirl stators based on CFD for a chemical product carrier
Zhongguo Jianchuan Yanjiu, 2017 The viscous self-propulsion flow fields of a model-scaled 55k DWT chemical product carrier fitted with a rudder-bulb-fin and a pre-swirl stator are numerically simulated based on the CFD general code FLUENT.

A Homogenization Method for Replacement Stator Models in an Aero-Engine
Aerospace, 2022 Generally, the high-fidelity finite element models of aero-engines comprise millions of degrees of freedom (DOFs). Although they can provide precise predictions of structural dynamics, the computational cost will be often unaffordable if appropriate ...

Fault tolerant control of a three‐phase PMSM by limiting the heat of an inter‐turn fault
IET Electric Power Applications, 2022 Inter‐turn faults are most commonly the initial stator winding fault in power trains with Voltage Source Inverters. Without counteractions, these faults can propagate and cause catastrophic failures in safety critical applications like all‐electric ...

Arbitrary d–q current sharing in three-phase winding sets of multi-phase machines
The Journal of Engineering, 2019 This study proposes a technique for arbitrary current sharing between winding sets of any multiple three-phase machine by using a decoupled control in two-dimensional orthogonal vector space decomposition subspaces.
