Special Issue Information
Dear Colleagues,
The move towards transportation electrification has made reliability considerations of electrical machines a stringent and predominant requirement. Failures can cause severe downtime and economic losses, as well as endanger human lives. Especially in the automotive and aerospace sectors, electrical machines are required to simultaneously deliver high performance while guaranteeing the appropriate reliability considerations.
It is clear that reliability must be a design objective from the very beginning of the design process. A bottleneck for failure of electrical machines is the insulation system. As power density values continue to improve through modern enabling technologies, their adoption can trigger undesired insulation ageing and degradation, compromising its dielectric properties. Therefore, adequate insulation design is needed to promote and enhance electric drive reliability at both the component and system levels.
This Special Issue will present scientific papers dealing with design for the reliability of electrical machines with special focus on the machine insulation system and the impact of their main ageing/stress factor. Articles on machine design, ageing mechanisms, lifetime degradation modelling, partial discharge detection and modelling, fault‑tolerant systems, real‑time fault detection, and diagnostics methodologies are invited for submission. Original research and practical contributions as well as surveys and state-of-the-art tutorials are welcome.

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.
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.
