Special Issue Information
Dear Colleagues,
In response to the increasing efficiency requirements of electric drives and line-start electrical motors, rotor/secundary hybridization of synchronous motors has emerged as a viable solution that can increase both efficiency and fault tolerance. Due to hybridization, the motor torque is developed by more than one phenomenon. In this category, line-start synchronous motor drives develop torque either by induction in a squirrel cage or synchronously due to reluctance and/or permanent magnet flux, making them highly recommended for direct replacement of old induction motors, whereas permanent magnet-assisted synchronous reluctance motor drives develop their synchronous torque due to both the reluctance and permanent magnet flux being more fault tolerant in cases of rotor faults.
This Special Issue aims to explore the fault tolerance of synchronous motor drives through design, fault diagnosis and control. It targets increasing fault tolerance through new designs, evaluation of innovative designs of synchronous motors in terms of transient and steady-state faulty operations, as well as new fault tolerant control strategies. This Special Issue covers the improvement of analytical and finite-element models in performance prediction as well as the development of the experimental setup to examine the behavior of synchronous motor drives under different faults, such as stator faults, demagnetization, broken rotor bars, eccentricity, and power converter faults. It considers a wide range of innovative solutions such us hybrid rotor synchronous motors, including line-start permanent-magnet synchronous motors (LSPMSMs), line-start synchronous-reluctance motors (SynRMs), permanent magnet-assisted synchronous reluctance motors (PMASynRMs), multi-phase Shincronous drives, etc.
This Special Issue focuses on the following topics:
- Analytical and finite element modelling as well as optimization of more fault tolerant synchronous motor drives;
- Transient and steady state operation prediction and measurement of faulty synchronous motor drives;
- Design and analysis of special types of synchronous motor drives like line-start permanent-magnet assisted synchronous reluctance motors, multi-phase hybrid rotor synchronous motors, etc.;
- Fault analysis of synchronous motor drives;
- Thermal modelling synchronous motor drives, particularly under faulty conditions;
- Condition monitoring of synchronous motor drives;
- Application of artificial intelligence in the performance parameters estimation, analysis, and design of synchronous motor drives;
- Solutions for variable speed capabilities as well as improved fault tolerant control solutions of synchronous motor drives;
- Studies comparing the efficiency, power factor, and reliability of synchronous motor drives.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed open access monthly journal published by MDPI.
