Permanent-magnet-assisted synchronous reluctance motors (PMa-SynRMs) have many advantages. This paper designs a PMa-SynRM and optimizes the machine structure to achieve high performance for electric vehicle (EV) application. Many variables such as width length of permanent magnets, air gap, shape tilted flux barriers are created study effects these on motor based finite element method (FEM). The results indicate that an influence d-q axis reluctances inductances, then affect torque; helpful...

Abstract Physicochemical features of nano-carbon (NC) particles significantly influence the microwave absorption performances NC-containing materials. Here, we report development rare earth neodymium (Nd)-doped barium ferrite (BaM) composites with carbon nanotubes (CNTs) and other NC materials (onion-like graphene oxide) to enhance absorption. Nd 0.15 -BaM containing 8% CNTs demonstrate a minimum reflection loss − 123.12 dB at 7.97 GHz, an effective bandwidth 5.46 GHz in 2–18 range. improve...

The energy and operation costs have always been a bottleneck, restricting the development of rural sewage treatment. This work proposes biocontact oxidation process driven by battery-free wind-solar power generation to implement automated An automatic machine learning model was designed predict performance system. Higher accuracy obtained using random standard deviation sampling (RSDS) data amplification method. Correlation analysis indicated that influent quality indicators had path...

To investigate the differences in bacterial communities of biofilms appurtenant facilities rural sewage collection systems, a pilot research setup was constructed. A study conducted using real collected area, and different were characterized Illumina HiSeq high-throughput sequencing technology. The results showed that there significant biofilm among annexes. from all four ancillary (drop manhole, turning inspection well, mud trap, direct well) contained some amounts denitrifying bacteria...

Low stiffness of serial robot is the main factor limiting its application in milling task. In order to improve characteristics robot, model established based on kinematics and Jacobian matrix. Then, for task, process analyzed cutting force introduced. Base that, further performance index proposed. At same time, avoid singular posture during process. Condition number introduced measure dexterity robot. A comprehensive optimization was established, optimized. Finally, with optimal are obtained.
