This article describes the electromagnetic analysis of high efficient hybrid motor, which comprises the salient features of switched reluctance motor (SRM) and spoke‐type brushless DC motor. The main objective is to develop a motor with a high‐power density and winding faulty capability. Furthermore, this research article extends in the manner to increase the power density of the motor through the sensitivity analysis on rotor geometry by replacing the rotating part of SRM and adopting the rotor of spoke type brushless DC motor, originating the hybrid motor with the high‐power density and enhanced efficiency. To ensure the winding fault capability, a SRM‐based stator winding is adopted. Then, the modelling process for hybrid motor 48 V, 1500 RPM, 2 kW, and 12.7 Nm are detail in both analytical and finite element methods. The electromagnetic analysis is carried out to estimate the torque characteristics and flux pattern of the proposed motor. Furthermore, the proposed motor is analysed with the selection of laminating core material among M 27 24 Ga, 36F155, 46F165, 47F165, M 420 50D, and arnon 7. This infers 36F155 material assists proposed motor has high‐performance characteristics. The vibration frequencies are investigated in modal aspects to estimate the natural frequencies of vibrations. These analyses are validated among analytical and finite element results under no‐load conditions.

Biofilm formation has incredible detrimental effects and has brought huge issue to our daily life. Pseudomonas aeruginosa is recognized as an opportunistic pathogen and its one of the antibiotic resistance mechanisms includes biofilm formation. To survive against harsh environmental conditions the microorganisms form an extracellular polymeric substance matrix. Natural products, particularly, marine natural products have been established useful in providing new chemical entities to mark biofilm inhibition and dole out as a rich source of privileged frames for studying chemical as well as biological applications. In the present study, antibiofilm potential of bioextract from Actinokineospora cibodasensis (MW513387) is tested against Pseudomonas aeruginosa (ATCC 27853) biofilm. The analysis of the quorum sensing modulation was done using exopolysaccharide (EPS) quantification and Cytotoxicity assays were performed to check toxicity. Scanning electron microscopy (SEM) was also conducted to visualize the mitigation of biofilm using the biocontrol agent. All the assays conducted evidently indicated that the potential bioactive compound from Actinokineospora cibodasensis has greater inhibition effect against pathogenic biofilm. In the near-term years it is expected that these pharmaceutical compounds from natural source be translated into antibiofilm drugs.

Doubly Salient Singly Excited Machine (DSSEM) inbuilt with the features as high torque density, high speed density, compactness, low maintenance, but the machine reduces its application due to its demerits as torque ripple. This study enhances the performance of switched reluctance motor (SRM) in the track of electromagnetic and mechanical characteristics. A 290 Volts, 10 Amps, 3000 rpm, 4 N-m SRM undergoes finite element (FE) characterization in the view of parameters like torque ripple. In the regard of torque characterization, the ripple torque is estimated under rated condition. FE analysis gives accurate results by 2D analysis. Torque ripple is the main concern in electrical machines, because these two are responsible for producing harmonics, vibration, and noise. So, a novel machine is designed to reduce the torque ripple content. The losses are considered as heat generation as a source of temperature rise in a motor, and the heat distribution is analyzed. The experimental setup is arranged to evaluate the simulation results with the current profile of FE analysis and prototype for verification.
