Experimental study of brushless generator with integrated exciter

Vestnik of Samara State Technical University. Technical Sciences Series, 2020
The paper studies an integrated starter-generator based on a synchronous machine with PM excitation (ISG), used to start an internal combustion engine (ICE) of an autonomous energy facility or vehicle and supply electric energy to its consumers. The purpose of the work is to obtain a mathematical model of the starting mode in the form of a system of ...

Dispersion Inhibits Thermal Mitigation of Pseudomonas aeruginosa Biofilms on Self‐Heating Surfaces

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Thermal mitigation of biofilm infections is promising in the lab. Clinical translation requires heat to be delivered from the implant surface while leaving surrounding tissue cooler. This study shows that bacteria may rapidly and reversibly disperse into these cooler areas, reducing treatment efficacy.

A Brushless Resonant Exciter Concept for Radial Flux Motors

IECON 2025 – 51st Annual Conference of the IEEE Industrial Electronics Society
This paper proposes a novel brushless electrically excited synchronous machine that employs inductive wireless transfer of rotor excitation power through the air gap. The magnetic parts of the machine fulfill the excitation function on top of the torque production, thusly achieving similar compactness as brushed electrically excited synchronous ...

Integrating Direct Air Capture Technology and Plasma Based Calcination for Sustainable Syngas and Concrete – An Experimental Investigation

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This study presents an experimental Proof‐of‐Concept of an electrified CO2${\rm CO}_2$ loop that combines DAC and GA‐plasma conversion. Atmospheric CO2${\rm CO}_2$ is captured and solidified as CaCO3${\rm CaCO}_3$, followed by plasma‐based calcination to regenerate CaO and with the possibility to split CO2${\rm CO}_2$ into CO for syngas synthesis. This

Brushless Wound Rotor Synchronous Machine Topology Using Concentrated Winding for Dual Speed Applications

IEEE Access, 2023
Permanent magnet (PM) machines have broad applicability and a rapid output rise due to their good power factor, high efficiency, and power density. However, with the recent high cost, unavailability, and demagnetization issues of PMs, the wound rotor ...

Suppression of DC Winding Current Harmonics in Wound‐Field Machines Under PWM Excitation by Using Active Voltage Injection and LC Low‐Pass Filters

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, the LC low‐pass filter is designed and connected in parallel with the DC winding of the MFMWF machine to suppress the high‐frequency sideband harmonics in the DC winding current for the first time. The suppression effect is validated by experiments.

Real‐Time Implementation of Finite Control Set Model Predictive Control for BLDC Motors With Dynamic Speed References on ESP32

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates the application of Finite Control Set Model Predictive Control (FCS‐MPC) for Brushless DC (BLDC) motor speed regulation under dynamic references, including sinusoidal, square, triangular, and sawtooth signals. A novel cost function is introduced to evaluate switching frequency effects, and the influence of different weighting ...

Transfer Function Model of a Brushless Exciter

Journal of King Saud University - Engineering Sciences, 1997
Brushless exciters are widely used in power stations to furnish the excitation current for the main alternators. These exciters are maintenance free and possess high gain and forcing margin. Transfer function models available for such exciters are somewhat complicated and deal with few variables.
