Research on Electromagnetic and Dynamic Properties of LPMBLDCM for Electromagnetic Launch
Huilai Li,Xiaomin Li 보안공학연구지원센터(IJUNESST) 2015 International Journal of u- and e- Service, Scienc Vol.8 No.1
In order to improve the thrust characteristics of moving-magnet type linear permanent magnet brushless DC motor (LPMBLDCM), the structural characteristics and magnetic field are analyzed. The influence of electrical parameters and structural parameters on the electromagnetic properties and thrust performance are researched by finite element analysis (FEA). The cogging force, back electromotive force (back-EMF), air-gap magnetic field distribution, mover velocity as well as thrust output are studied by taking some practical parameters into account, including pole/arc coefficient, air-gap width, voltage and current. The LPMBLDCM system is established, and some relevant tests are taken to verify the simulation results. Simulation and experimental results show that the thrust and mover velocity are mainly affected by some key parameters. The results will surely provide the reference and guidance for the optimization of electromagnetic and thrust characteristics of LPMBLDCM.

Sulfamethoxazole (SMX) is a widely used antibiotic drug in medical applications resulting in its ubiquityin water and wastewater. Most of the treatment processes are inefficient in destroying SMX in water. Theheterogeneous electro-Fenton (EF)process shows promise in the non-selective degradation of antibioticdrugs in water and wastewater. Fe2O3/MXene-x (x is the ferric ion loading) was fabricated on 2DMXene carriers by hydrothermal method. The Fe2O3/MXene-x substrates were characterized by electronmicroscopic, X-ray, and molecular spectroscopic methods. Degradative products of SMX were identifiedby free radical quenching and LC-MS measurements. Electron micrographs show that Fe2O3 particulatesare uniformly distributed on MXene nanosheets. Fe2O3/MXene-x coated graphite was used as a cathodewith titanium anode for in situ generation of H2O2 required to produce free radicals (e.g. OH and O2 – ) todestroy SMX. Three possible SMX degradation routes by the electro-Fenton process were proposed. SMXand intermediates are eventually mineralized as CO2 and H2O. The new electrocatalyst shows reducedmetal ions leaching and good stability in repeated use cycles. This work offers a new electro-Fentonmethod to destroy antibiotic drugs in water and wastewater.
