Special Issue Information

Dear Colleagues,

This Special Issue aims to record the findings of latest studies and research activities on materials, production processes, design particularities, configuration conception, fault tolerance and measurement techniques regarding the development of high-performance electrical machines. In this regard, papers dealing with the recent research, application and configuration of constitutive parts, design and operation of high-performance electrical machines are welcome.

The main topics of interest include but are not limited to the following:

  • Thin iron laminations and low-loss alloy magnetic steels implemented in electrical machine cores.
  • Winding configurations and cooling techniques for high-performance electrical machines.
  • Multi-phase electrical machines.
  • Permanent magnet materials and associated loss reduction techniques.
  • Harmonic losses and converter control enabling high efficiency drives.
  • Ceramic and electromagnetic bearings for high-speed and high-efficiency machines.
  • Machine topologies and design considerations favoring high-performance machines.
  • Measurement techniques for high-performance machines.
  • Lamination cutting and core building factor loss reduction methods.
  • Design of fault-tolerant electrical machines.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

The extreme environmental issues and the resulting need to save energy have turned attention to the electrification of energy applications. One of the key components involved in energy efficiency improvements is the appropriate conception and manufacturing of electric machines. This paper overviews the electromagnetic analysis governing the behavior of permanent magnets that enable substantial efficiency gains in recent electric machine developments. Particular emphasis is given to modeling the properties and losses developed in permanent magnets in emerging high speed applications. In addition, the investigation of properties and harmonic losses related to ferromagnetic materials constituting the machine magnetic circuits are equally analyzed and discussed. The experimental validation of the implemented methodologies and developed models with respect to the obtained precision is reported. The introduction of mixed numerical techniques based on the finite element method intended to appropriately represent the different physical phenomena encountered is outlined and discussed. Finally, fast and accurate simulation techniques including aggregated lumped parameter models considering harmonic losses associated with inverter supplies are discussed. Full article
