“…The operating stability and durability of the PMSM are constrained by greater temperatures at the hot spots and the inefficient heat dissipation, as discussed earlier. The proper quantification of electric motor heat generation and sophisticated coupled motor cooling practices are topics of considerable importance [69]. Generally, air-cooling, water-cooling, oil-cooling, water-glycol-cooling and phase change evaporative-cooling are the active cooling strategies for the thermally stable operation of an electric motor.…”

“…Higher coolant flow rate tests were performed with higher forced convection heat transfer coefficients of up to 5000 W/(m 2 •K). The results indicated a substantial reduction in the winding temperature [69]. The water-cooled model was examined considering both the radial heat flow in the active portion of the system and the axial heat flow through the end-winding area and the shaft [78].…”

This paper gives a comprehensive review of advanced cooling schemes and their applications to the permanent magnet synchronous motors (PMSMs), as well as investigating the electrical motor’s topologies its thermal design issues, materials and performances. Particularly, the electromagnetic and electric performances, machine sizing, together with the structural design, are given. In addition, the work addresses the motor’s material design and properties along with its insulation performance, which is the main goal of optimization. Mainly, thermal mapping with analysis is provided according to the different cooling methods, including air-cooling, water-cooling, oil-cooling, heat-pipe-cooling, potting silicon gelatin cooling, and as well as cooling strategies for tubes and microchannels. The most common special features and demands of the PMSMs are described in the appearance of the motor’s failures caused by uncontrolled temperature rise. In addition, heat sources and energy losses, including copper loss, core loss versus motor speed, and output power, are analyzed. The review of the proposed cooling methods that will achieve the required heat transfer of the PMSM is presented with numerical simulations and measurements data. A review of numerical methods and results, including the finite element methods (FEM), such as the Ansys CFD software, to obtain a high-accuracy thermal mapping model of the PMSM system is given. The revived methods and design requirements due to PMSM temperature profile and cooling flow at different rotor speeds and torque loads are investigated. Finally, the motor design recommendations, including the newly developed cooling solutions, which enable it to effectively redistribute the temperature and heat transfer, increasing the efficiency of the PMSM machine, are laid out.

“…In electrical machines, one of the most common multi-physics methods is to solve the electromagnetic domain for the calculation of the losses and share them with a thermal model [55]. This coupling can be either one-way in which only losses are passed to the thermal simulation or two-way in which the calculated temperature is also sent back to the electromagnetic simulation in each iteration to calculate power losses accordingly [56].…”

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.
