Electrical Machines for Electric Vehicles and Renewable Energy Systems

Dear Colleagues,

In recent decades, electrical machines have been the subject of massive developments in order to improve their performance and reliability, and to create new design concepts to expand their applications in different fields. They are considered important components in electricity generation and consumption, making contributions of more than 90% and 50% to them, respectively. Their importance is increasing even more alongside the desire to create a more sustainable, carbon-neutral economy, which can be achieved by advancing electrification in renewable energy systems and electric vehicles, including electric on-road (cars, trolleybuses, buses, trucks, and bicycles), air, marine, and rail vehicles. 

Modern electrical machines are required to demonstrate reduced emissions, better performance, and more reliable operation. As a result, there is constant demand for new and innovative electrical machinery concepts and technologies to meet emerging needs. Innovations in material science and novel thermal management concepts have provided many exciting features in advanced electric machines. Additionally, additive manufacturing, known as 3D printing, has created new opportunities for low-volume designs.

This Special Issue will focus on the advanced modelling of electric motors and generators for application in electric vehicles and renewable energy systems. Finite element method (FEM) designs, including coupled electromagnetic, thermal and mechanical analyses, will suit the scope of this Special Issue. The application of newly developed thermal management materials in electrical machines; reliability-focused electric motor design and analysis; novel stator housing manufacturing, considering improved cooling schemes; and additive metal manufacturing with a focus on improved cooling technologies will be acknowledged within this Special Issue.  We welcome any original research papers on the modelling of electrical machines.

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

• Finite element modelling and analysis of radial, axial and transverse flux motors and generators for e-mobility and renewable energy systems;
• Multi-physics electrical machine design, considering electromagnetic, thermal and mechanical aspects;
• Coupled electromagnetic–thermal finite element modelling and optimization of electrical machines;
• Electrical machine design, considering thermal management aspects;
• Heat transfer in electrical machines with thermal calculations, lumped parameter thermal networks, and computational fluid dynamics (CFD);
• Machine loss analysis coupled with thermal finite element and CFD simulations;
• The effect of manufacturing methods on the performance of electrical machines;
• Manufacturing challenges in electrical machines;
• Additively manufactured motor and generator components used to improve heat transfer in electric vehicles;
• Reliability-based electrical machine design for electric vehicles and renewable energy systems;
• Aging of electrical machines due to thermal and electrical stresses;
• Accelerated life tests in modern electrical machines.
