High Performance Permanent Magnet Synchronous Motor Drives

Dear Colleagues,

Permanent magnet (PM) synchronous motor drives are widely used in industrial applications, electric vehicles, and electrical devices, thanks to their high torque density, fast dynamic response, and good overload capability. New challenges are appearing in the design of synchronous motors due to the appearance of new technical and socio-economic requirements. Moreover, recent applications require an extended sensorless capability, an outstanding flux-weaking capability, and a wide constant-power region.

This Special Issue aims to collect original research and review articles on different design methodologies or solutions for PM motors and PM-assisted synchronous reluctance motors, suited for meeting the demanding specifications of the emerging applications. Since the price of PMs is continuously increasing, special solutions and experience in reducing rare-earth materials are welcome.

Topics of interest include but are not limited to the following:

• PM motor drives designed to achieve an extended sensorless capability;
• Control techniques to achieve high flux-weakening capability;
• Motor design solutions to expand self-sensing capability;
• Motor design solutions to get wide constant-power region;
• Optimized PM design, including reverse-saliency or hybrid excitation machines;
• Rare-earth-magnet-free machines;
• Analytical, semi-analytical, and numerical models.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
