“…In the vibration and noise in a four-pole PMSM, the spatial first order (circular mode second order) often presents a problem, as reported in the literature [8,9]. With regard to the time order, the medium to high range (1 kHz to 3 kHz) is where auditory problems occur [18,19]. Thus, in this paper we attempt to reduce vibration by focusing on these points.…”

SUMMARYGlobal warming and the problem of successfully incorporating environmental safeguards are promoting the need for a more power-efficient motor. Therefore, as a driving source, permanent magnet synchronous motors (PMSMs) with concentrated winding are widely used in a variety of fields. However, a PMSM with a concentrated winding generates more vibration than one with a distributed winding because of the radial electromagnetic force. This paper describes the effect of a new skewed rotor on the characteristics of a concentrated winding PMSM. We investigated this effect by three-dimensional finite element method (3D FEM) analysis and measurement. We also demonstrate that the proposed rotor is effective in reducing the radial electromagnetic force without decreasing motor efficiency. C⃝ 2014 Wiley Periodicals, Inc.

“…Past literature has noted that spatial first-order (second-order annular mode) of the vibration and noise from a 4-pole PMSM often becomes a problem (17) (18) . Time order is the mid-high range band (1 kHz-4 kHz), which is problematic in terms of auditory perception (17) (18) . Therefore, vibrational factors of the motor were analyzed by focusing on the following points.…”

MemberThis paper describes the influence of rotor eccentricity on the vibration characteristics of a concentrated winding interior permanent magnet synchronous motor (IPMSM) by using a finite element method (FEM) and several measurements. The rotor eccentricity primarily caused an increase in radial electromagnetic force. In addition, an IPMSM with rotor eccentricity has higher vibration acceleration than an IPMSM without rotor eccentricity.

“…However, it is known that it is difficult to estimate the Young's modulus of winding. For the analysis of the radial force, vibration and acoustic noise, several papers have been published (Ishibashi et al, 2003, Shiohata et al, 1998, Munoz et al, 2003. They gave the amplitudes as well as the frequencies of the radial electromagnetic force.…”
