This paper first derives the characteristics of radial electromagnetic force considering
different types of current harmonics. By using two-dimensional fast Fourier transform, the …

This paper aims to clarify global and local force harmonics and their effects on vibration in
permanent magnet (PM) synchronous machines. The local force includes both the tangential …

The vibroacoustic characterization of an electric powertrain which consists of a permanent
magnet synchronous motor and a gearbox for electric vehicles is analyzed in this paper …

Noise-vibration-harshness (NVH) analysis is becoming increasingly important to
comprehensively understand, identify, and mitigate the vibration and noise of the electric …

In this study, we introduce an optimal design for a spoke-type interior permanent magnet
(IPM) motor that can minimize PM weight by allowing irreversible demagnetization, unlike …

The normal electromagnetic force wave plays a critical role in electromagnetic vibration of
permanent magnet synchronous linear motors (PMSLMs). In this paper, a PMSLM designed …

Conventional electromagnetic vibration analysis methods mainly focus on the spatial
harmonic components of the radial force density. Because they do not consider time …

Abstract Background and Purpose The comfort of electric vehicles (EVs) is closely related to
the vibroacoustic performance of integer-slot permanent magnet synchronous motors …

This paper discusses a motor that was designed to satisfy the size constraints of system by
using ferrite magnet and has the same performance as rare-earth magnet motor. In general …

Interior permanent magnet synchronous motors (IPMSMs) have been widely used in a
variety of applications. The IPMSM will generate vibration as well as functioning like other …
