How P. aeruginosa cells with diverse stator composition collectively swarm. [PDF]
mBioSwarming is a macroscopic phenomenon in which surface bacteria organize into a motile population. The flagellar motor that drives swarming in Pseudomonas aeruginosa is powered by stators MotAB and MotCD.

Torque-speed relationship of the flagellar motor with dual-stator systems in Pseudomonas aeruginosa. [PDF]
mBioThe single polar flagellar motor in Pseudomonas aeruginosa is equipped with two stator systems, MotAB and MotCD, both driven by H+ ions. The torque-speed relationship for flagellar motors with two stator systems has not been explored previously.

A novel spherical ultrasonic motor with wire stators and measuring torque and preload via a new method. [PDF]
Sci Rep, 2023 The present study introduces a multi-degree-of-freedom (MDOF) ultrasonic motor, which is capable of driving a spherical rotor using spiral wire stators and a piezoelectric stack actuator. Wire stators and piezoelectric stack actuators enable the proposed

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 ...

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 ...

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 ...

Dynamic Hybrid Flagellar Motors—Fuel Switch and More
Frontiers in Microbiology, 2022 Flagellar motors are intricate rotating nanomachines that are powered by transmembrane ion gradients. The stator complexes are the powerhouses of the flagellar motor: They convert a transmembrane ion gradient, mainly of H+ or Na+, into rotation of the ...
