Special Issue Information

Dear Colleagues,

Electrical machines were invented more than 200 years ago, and their fundamental design procedures have been developed over decades and are still evolving. The conventional manufacturing techniques of electrical machines have already reached their desired level, and it seems that there is less possibility to do research and development on these techniques. As a result, new design methods and manufacturing techniques are required to provide outstanding and profound impacts on electrical machines’ evaluation process. In other words, advanced modern techniques allow the electrical machines’ manufacturers to design novel electrical machines with whatever complex shapes, structures, and advanced materials by implementing the modern computational electromagnetic, thermal, and material approaches. The demands for clean energy technologies for different applications, for instance, wind power, electric vehicles, and electric powertrains, are rising rapidly. The demand metrics are mainly concentrated on high power density, high efficiency, and lightweight electrical machines.

Therefore, the additive manufacturing approach is considered a new manufacturing technology method and is evolving dynamically in recent years. It is advancing and achieving as the key enabling technology in a wide range of applications, from medical sciences to the aerospace and automotive industries. This novel approach opens a new path to overcome the conventional manufacturing problems and challenges by providing more design freedom, new ranges of materials, and lightweight and complex geometries.

This is a call for papers for a Special Issue on "Future trends in advanced design of electrical machines, drives and electric vehicles using additive manufacturing approaches". This Special Issue will provide a forum for researchers and practitioners to exchange their latest theoretical and technological achievements and identify critical issues and challenges for future investigation in the design of electric machine drives using additive manufacturing approaches. The submitted papers are expected to raise original ideas and potential contributions to theory and practice. Topics include, but are not limited to, the following research areas:

- Iron core;

- Windings and insulations materials;

- Permanent magnets;

- Mechanical and structural parts;

- Thermal management systems;

- Integrated electrical machines and drives (IMD);

- Multi-material systems for the fully additively manufactured electrical machines.

The main issue of the switched reluctance motor (SRM) is its noise and vibration caused by high torque ripples on the rotor’s shaft. Many methods have been developed for improving the torque characteristic of the SRM. For example, design optimization is one of the promising approaches to the noise and vibration reduction of the SRM. Particularly, topology optimization (TO) of the stator and rotor can be highly beneficial to addressing the torque ripple issue. However, the TO of the SRM appears to be computationally demanding. To overcome this issue, this study proposes a method aiming to reduce the computational complexity of the TO through the reduction of the design space. Particularly, this paper presents a sensitivity analysis of a list of unique design parameters of the SRM and their influence on the average torque of the motor and the torque ripple of the motor. By applying the sensitivity analysis, the design space of the TO could be reduced, leading to a considerable decrease in the TO computational burden. Additionally, valuable conclusions on the geometrical parameters’ influences on the SRM torque and torque ripple have been drawn. Full article

Additive manufacturing (AM) is a key technology for advancing many fields, including electrical machines. It offers unparalleled design freedom together with low material waste and fast prototyping, which is why it has become to focus of many researchers. For electrical machines, AM allows the production of designs with optimized mechanical, electromagnetic and thermal parameters. This paper attempts to give the reader an overview of the existing research and thermal solutions which have been realized with the use of AM. These include novel heat sink and heat exchanger designs, solutions for cooling the machine windings directly, and additively manufactured hollow windings. Some solutions such as heat pipes, which have been produced with AM but not used to cool electrical machines, are also discussed, as these are used in conventional designs and will certainly be used for additively manufactured electrical machines in the future.
