Optimization and Simulation of Permanent Magnet Motors

Dear Colleagues,

Electric machines are the main workhorses of our modern world. Among them, permanent magnet (PM) machines have reserved a special place for applications where high efficiency combined with high torque density and reduced size and weight are important. High-performance applications often require the electric machine to fulfill several conflicting requirements, thus pushing its design electromagnetically, thermally, and mechanically to the edge of feasibility. In such cases, machine designers face a serious challenge and need to resort to reliable multiphysical models combined with mathematical optimization as an automated decision-making tool.

This Special Issue focuses on simulation and optimization of permanent magnet machines used as a design tool. The specific topics of interest include (but are not limited to) the following:

• Analytical, semi-analytical, and numerical models;
• Electromagnetic, thermal, mechanical, and multiphysical models;
• Advanced iron loss and winding loss models;
• Simulation model tuning based on testbench measured data;
• Deterministic, heuristic or meta-model based single-objective and multiobjective optimization of PM machines;
• Reduction of computation efforts in optimization of PM machines using time-efficient preparation and solving of machine models and/or parallelization of the optimization tasks;
• Introduction of improved or novel optimization methods applied to PM machine design;
• Application-targeted (aerospace, traction, high-speed, etc.) simulation and optimization.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
