Finite element analysis (FEA) has rapidly developed in the past three decades. In case of the magnetic field analysis, many researchers have proposed different electric machines by using FEA in order to achieve high efficiency, high torque density, low torque ripple, and so on. For further development of electric machines, this paper presents a literature survey on the state‐of‐the‐art research trends of the electric machine related to FEA in the last 3 years. © 2017 Institute of Electrical Engineers of Japan.

“…Permanent magnet synchronous motors (PMSMs) are widely used for many industrial applications, such as electric vehicles, household electric appliances, and factory automations. These diverse applications require higher power density, higher efficiency, lower acoustic noise, and fewer vibrations (1) (2) . Carrier harmonic loss, noise reduction (3) (4) , and vibration reduction control (5) have been studied using multi-three-phase PMSMs that can increase the degree of freedom of the current control and be constructed with commonly used three-phase inverters.…”

Real-time Dynamic Eccentricity Detection by Analyzing Harmonic Components of No-load Line-line Voltages in Multi-three-phase PMSMs

Permanent magnet synchronous motors (PMSMs) are widely utilized for many purposes owing to their high efficiency. Such frequent applications require less noise and fewer vibrations. This work focuses on multi-three-phase PMSMs that can independently control the current among winding groups to suppress the vibrations caused by air gap imbalances, which must be detected for suppression control. The representative effects of air gap imbalance include static and dynamic eccentricities. Dynamic eccentricity varies the air gap length in time; therefore, the instantaneous detection of the air gap length condition is necessary for suppression control. We propose a method that instantaneously detects dynamic eccentricity using the fundamental and fourthorder harmonic components of no-load line-line voltages, which are easily measurable in practical manufacturing processes. The proposed real-time detection method is applied to a finite element analysis (FEA) model with dynamic eccentricity, and confirm its detection ability is confirmed experimentally.

“…Permanent magnet synchronous motors (PMSMs) are widely used because of their many advantages such as maintenance‐free operation, high controllability, robustness against adverse environmental conditions, high efficiency, and high power‐factor operation . Recently, there has been a great demand for energy saving because of environmental problems; thus, highly efficient motors are in demand in various fields . This, along with the development of high‐performance rare earth (RE) permanent magnets (PMs, usually Nd–Fe–B), has expanded the application fields of PMSMs, such as factory automation, home appliances, and automobiles .…”

This paper presents an overview of the recent technical trends in permanent magnet synchronous motors (PMSMs), especially the rare earth (RE)-less PMSMs that have been developed in Japan. The RE-less PMSMs, along with PMSMs with reduced RE permanent magnets (PMs), PM-assisted synchronous reluctance motors (PMASynRM) with ferrite PMs, spoke-type interior PMSMs (IPMSMs) with ferrite PMs, and axial-gap PMSMs with ferrite PMs, are reviewed.
