“…A coupling FEM, empirical equations, and 2D/3D axi-symmetric methods have been used in [46] to calculate the electromagnetic losses, the mechanical losses, and the fluid and solid cooling calculations, respectively. FEM and CFD have been coupled in [44] for the thermal analysis of a PMSM. FEM has been used in [100] for both electromagnetic and thermal studies.…”

Permanent magnet (PM) machines have gained increasing attention from the industry because of their potential merits over conventional electrical machines. High‐temperature level in electrical machines is a major factor that can adversely impact the performance and health conditions of these machines. These effects need to be minimized to make them competitive with currently operational machines in the industry. It can be done by performing a thorough thermal analysis of the prototype during the design process and proper online thermal monitoring of the machine during the operation stage. Thermal modelling is a powerful tool for achieving such goals in both cases. This paper aims to review the state‐of‐the‐art of thermal modelling techniques and provide a detailed comparison of them in PM machines. The fundamental concepts of heat transfer and sources of heat in PM machines are first discussed. Then, different thermal modelling techniques, including thermal subdomain models (TSMs), lumped parameter thermal networks (LPTNs), finite element models (FEMs), computational fluid dynamics (CFD), reduced order models (ROMs), and hybrid thermal models (HTMs) are introduced and compared. Finally, the utilization of these models in the thermal design, control, and monitoring of PM machines is studied.

“…Sometimes, simplifying assumptions are also considered to shorten the simulation time. For instance, it can be assumed that heat sources are uniformly distributed on the surface, the ambient temperature is constant during the study, or some losses are insignificant [41,[43][44][45][46][47][48][49][50][51][52][53][54].…”

The paper describes 3D analysis of the thermal field in permanent magnet synchronous machine and reluctance synchronous machine able to work at high internal temperature (HT° machine). 3D coupled fluid-thermal model of projected machine is created to obtain the distribution of thermal field and air flow and to calculate the average temperature of the most sensitive parts such as coils and permanent magnets. The influence of the surface state of the machine housing on its heating is examined. The points of the highest temperature inside analyzed machine are localized too. The comparison of thermal properties and the possibility of working at high temperatures for both kinds of machines has been carried out.

Purpose The purpose of this paper is to present a comparison between reluctance synchronous machine-enabling work at high internal temperature (HT° machine) with laminated and solid rotor. Design/methodology/approach To obtain heat sources for the thermal model, calculations of the electromagnetic field were made using the Opera 3D program including effect of rotation and the resulting eddy current losses. To analyse the thermal phenomenon, the 3D coupled thermal-fluid (CFD) model is used. Findings The presented results show clearly that laminated construction is much better from a point of view of efficiency and temperature. However, solid construction can be interesting for high speed machines due to their mechanical robustness. Research limitations/implications The main problem, despite the use of parallel calculations, is the long calculation time. Practical implications The obtained simulation and experimental results show the possibility of building a machine operating at a much higher ambient temperature than it was previously produced for example in the vicinity of the aircraft turbines. Originality/value The paper presents the application of fully three-dimensional coupled electromagnetic and thermal analysis of new machine constructions designed for elevated temperature.
