Electric machines are important devices that convert electrical energy into mechanical energy and are extensively used in a wide range of applications. Recent years have seen an increase in applications where electric motors are used. The frequent use of electric motors in noise-sensitive environments increases the requirements placed on electric motors intended for these applications, especially when compared to electric motors commonly used in industrial applications. This paper provides a comprehensive review of electric motor noise. Firstly, a brief introduction to noise is given. Then, the sources of electromagnetic noise and vibration in electric machines, including mechanical, aerodynamic and electromagnetic factors, are presented. Different methods such as analytical, numerical and semi-analytical for calculating electromagnetic force, natural frequencies and noise are also analyzed. Various methods for noise reduction are presented, including skewing, stator and rotor notching and slot opening width. Finally, noise measurement standards and procedures are described.

“…Regarding the rotor, the most typical strategies are to modify the shape [8][9][10][11] and the height [12,13] of the permanent magnets. Some authors also vary the magnetization direction of the magnets [12] or include different notch geometries to the rotor [14][15][16][17].…”

Sensitivity Analysis of the Design Parameters of Permanent Magnet Synchronous Motors for Vibration Reduction

The use of electric motors, and particularly, Permanent Magnet Synchronous Motors, is increasing in recent years, and their vibration response is one of the most crucial aspects regarding their behaviour. Thus, the reduction in vibrations is one of the key objectives when optimizing electric motors. In an initial design state, the influence of the main design parameters on the behaviour of the machines is not always clear. For that reason, this work presents a global sensitivity analysis procedure that allows identifying the most influential design parameters and determining guidelines to optimize the design of Permanent Magnet Synchronous Motors. First, the analytical calculations employed to estimate the electromagnetic torque and the vibration response of the machine are described. Then, the sensitivity analysis procedure, based on the Monte Carlo method, is presented, and the conditions to apply the method successfully and accurately are analysed. Finally, the sensitivity analysis is performed for a particular electric motor design, and some general design guidelines are deduced, which can be extrapolated to similar machines.

“…In contrast, radial electromagnetic force is the primary source [3,4]. Effective studies such as stator and structure optimization [5], pole-arc coefficient [6], slots design [7], improving the rotor structure [8], and decrease of harmonics of the air gap flux density [9] can result in improvement of electromagnetic filed performances. As for rotor skewing, it also weakens cogging torque and torque ripple to improve electromagnetic field characteristics [10,11].…”

Permanent magnet synchronous motors (PMSMs) have recently been popular and widely used for electrical vehicle developments in the automobile industry to replace internal combustion engines due to their ability to perform at higher efficiency. This paper uses the PMSM in fuel cell vehicle electric air compressors. To ensure that the PMSM performs at higher efficiency, some field performance, such as electromagnetic field, must be improved. In this paper, a comparison between the electromagnetic forces components in the presence of current harmonic. The data indicates that the amplitude of electromagnetic forces for both radial and tangential components are not the same, particularly in lower orders. However, radial forces contribution is greater than tangential forces. A structural optimization method reduces the radial electromagnetic (RE) forces to improve PMSMs efficiency. The optimization method involves changes in the PMSMs design values and improving the electromagnetic field performance. The RE forces found to dominate the tangential electromagnetic (TE) forces, and it is amplitudes corresponding to 2,4 and 6-order are minimized by 31.1%, 28.5%, and 15.9%, respectively.
