Investigation of noise and vibration characteristics of an IPMSM with modular‐type winding arrangements having three‐phase sub‐modules for fault‐tolerant applications

Abstract

The noise and vibration level in modular‐type permanent magnet synchronous machines with fractional slot concentrated windings (FSCW) is considered to be an important design consideration, particularly for applications requiring fault tolerance. In this work, an interior permanent magnet synchronous machine (IPMSM) with FSCW is designed in a modular manner by dividing its stator windings into different arrangements having independent three‐phase sub‐modules with separate neutral points. First, the modular concentrated winding arrangement is studied to investigate the radial forces, vibration, and the associated noise level in the prototype machine having three‐phase sub‐modules under open‐circuit fault conditions. Then, another type of distributed three‐phase sub‐module winding arrangement is analysed to further investigate the vibration and noise level in the same prototype machine under the same operating conditions. A detailed two‐dimensional (2D) fast Fourier transform analysis is performed to investigate and compare the machine radial forces, induced harmonics, and sub‐harmonics for the two analysed winding arrangements. Considering the advantages and disadvantages of both the winding arrangements, the third type of mixed concentrated and distributed three‐phase sub‐modules winding arrangement is introduced in this work, combining the first two winding design approaches. A comprehensive harmonic (3D) structure, along with the vibration and noise analysis, is performed using a multi‐physics model analysis for all the winding arrangements under different three‐phase sub‐modules open‐circuit fault conditions. Lastly, the vibration levels of all the machine prototype models under different winding arrangements are experimentally validated. Moreover, the different modular types of winding arrangements are deeply investigated in this work to suggest the best winding arrangement approach that enables the machine to work in a wide range of applications requiring lower power levels or under critical, faulty, and hostile conditions. The proposed winding arrangement has reduced stator deformation with a reduced vibration and noise level under three‐phase sub‐modules open‐circuit fault‐tolerant conditions that can be used according to process requirements.

Enhanced Image Denoising with Diffusion Probability and Dictionary Learning Adaptation

“…Image denoising (ID) aims to preserve the main features of the original image while separating the image signal from the noise signal [2]. However, noise in images exhibits diverse distribution characteristics and can be influenced by factors such as image acquisition and transmission, leading to two primary categories: additive noise and quantization noise [3]. Current image denoising methods fall into three main categories: traditional filter-based methods, model-based methods, and deep learning (DL) methods [4].…”

Coupled Magnetic Field and Thermal Analysis Model for an IPMSM With Modular Three-Phase Winding Topologies for Fault-Tolerant Applications

“…Meanwhile, the thermal behaviour of multiphase machines has been investigated in many existing research studies [11][12][13]; however, there are very limited contributions to the research study on the thermal investigation of multi threephase machines. [14] Discusses the electromagnetic design and performance evaluation of the dual three-phase machine, while [15] and [16] presents a detailed investigation about the radial forces and torque response of multi-sector machine design and its electromagnetic considerations. The multisector machine has a multi three-phase winding arrangement in which each three-phase winding set is located in separate sectors of the stator.…”
