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.

“…The d-q parameters and phase flux linkage harmonics are studied to relate between the d-q parameters and torque ripple. The winding placement in a 6-pole 12-slot SRM is considered in the study, for ripple torque optimization, to distribute the electromagnetic field equally, and to reduce the vibrations [5,6]. The electromagnetic exciting force of an Integrated Starter and Generator is reduced which results in Noise and Vibrations caused from the tangential, radial force and torque ripples of the ISG.…”

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.

“…Asymmetric rotor flux barriers and rotor skewing are two of the suggested design methods that can reduce torque ripples in SyRM by half and two-thirds, respectively. In terms of motor design, the permanent magnet is positioned in the auxiliary poles of the stator, and the magnet orientation guarantees that the motor produces more average torque with less cogging torque is mentioned in [16]- [18].…”

This research article explores a comparative investigation on synchronous reluctance motor (SyRM) for electrified transportation system. The SyRM has salient features like absence of magnet, singly excited but it shrinks its application due to high torque ripple aspects. The novelty of the proposed work is the rib and flux barrier of the rotor in SyRM are modified in order to achieve low torque ripple without affecting the average torque of the motor. Analysis in the electromagnetic domain infers to enhance the sustainability and reliability of the transportation system. So, it results in the reduction of torque ripple, leads to minimize the acoustic noise. This article delivers the geometric optimization to achieve SyRM with low torque ripple. The finite elemental analysis infers the torque ripple, losses and unbalanced magnetic force for SyRM. The notched and round barrier type SyRM with one-layer results acts as superior motor among different layers and geometries. The experimental arrangement is carried out in real time vehicle and the results are obtained for different loading conditions and validated with FEA findings.
