This paper delves into the accurate evaluation of iron loss in permanent magnet synchronous machines, with special emphasis on traction applications. First, iron loss models from the literature are comparatively assessed based on the criteria of their effectiveness and accessibility in terms of required steel data. The primary challenges associated...
This article deals with the investigation of iron losses in toroidally wound laminated magnetic cores excited with wide-bandgap-device-based power electronic converters. The study aims to analyze the impact of selected pulsewidth modulation voltages on the iron losses, through an extensive experimental measurement campaign. In particular, four toro...
High frequencies are ubiquitous in present-day power applications: most electrical equipment, like rotating machines, are supplied by pulsewidth modulation (PWM) switching inverters, often working at tens or hundreds of kilohertz. PWM is responsible for minor cycles along the major hysteresis loop of the magnetic core, lasting a few microseconds. S...
This paper proposes a new magnetic model self-identification technique for synchronous machines to build the flux-map look-up tables (LUTs). Provided the shaft is free to turn, an alternating self-acceleration and deceleration sequence is envisaged for identification without a dedicated experimental rig or additional hardware. Respect to previous w...
Magnetic structures have attracted a great interest due to their multiple applications, from physics to biomedicine. Several techniques are currently employed to investigate magnetic characteristics and other physicochemical properties of magnetic structures. The major objective of this review is to summarize the current knowledge on the usage, adv...
