“…19. From the Fast Fourier Transform (FFT) analysis, it is obvious that the current harmonics of the proposed LSPMSM is lower than the other two motors and this leads to decrease in stray loss due to current harmonics [23]. In addition, the performance comparison of IM, Conventional LSPMSM and proposed LSPMSM is shown in the Table II.…”

Emerging efficiency standards indicates the demand of implementing highly efficient motors to reduce energy consumption and global warming, which is a worldwide concern. Owing to this, IE4 Efficiency line start permanent magnet synchronous motors (LSPMSM) contribution is increasing to a greater extent in the industrial motor market. This paper presents a new rotor configuration for a 2.2kW, 4 pole LSPMSM which is designed to meet efficiency beyond IE5 along with good power factor. The steady state and transient performance of the motor is optimized by using finite element analysis (FEA) software. From the results, it is evident that the proposed motor meets beyond IE5 efficiency level with 10% reduction in its length. Further reducing the length up to 30%, the motor sustains at IE4 efficiency level. To illustrate the optimum performance of the proposed design, the performance of the motor is benchmarked with identical radial type LSPMSM and commercially available IE2 induction motor. The FEA results of the proposed design are validated with the prototype development and testing. Consequently, this topology is both technically competent and cost effective, particularly for round the clock operation.

“…Composite solid rotor was used in LSPMSM to enhance the performance of the motor (Yan et al , 2018). Voltage harmonics on input power consumption, losses, energy efficiency and torque pulsations of HVLSPMSM were studied (Sethupathi et al , 2022). The effect of stator faults on LSPMSM voltage and current was studied in literature (Fonseca et al , 2020.).…”

Purpose The purpose of this paper is to present the influence of inter-turn short circuit faults (ITSF) on electromagnetic vibration in high-voltage line-starting permanent magnet synchronous motor (HVLSPMSMS). Design/methodology/approach In this paper, the ampere–conductor wave model of HVLSPMSM after ITSF is established. Second, a mathematical model of the magnetic field after ITSF is established, and the influence law of the ITSF on the air-gap magnetic field is analyzed. Further, the mathematical expression of the electromagnetic force density is established based on the Maxwell tensor method. The impact of HVLSPMSM torque ripple frequency, radial electromagnetic force spatial–temporal distribution and rotor unbalanced magnetic tension force by ITSF is revealed. Finally, the electromagnetic–mechanical coupling model of HVLSPMSM is established, and the vibration spectra of the motor with different degrees of ITSF are solved by numerical calculation. Findings In this study, it is found that the 2np order flux density harmonics and (2 N + 1) p order electromagnetic forces are not generated when ITSF occurs in HVLSPMSM. Originality/value By analyzing the multi-harmonics of HVLSPMSM after ITSF, this paper provides a reliable method for troubleshooting from the perspective of vibration and torque fluctuation and rotor unbalanced electromagnetic force.
