“…Thermal resistances for the conduction heat transfer paths are calculated from the dimensions and thermal conductivity of each component of the motor. Radiation, in turn, is computed from emissivity and view factor coefficients and component surface area [35,38,39]. Based on the data on temperature loss, and on the velocity distribution of the cooling fluid in the cooling channels depending on the machine, the thermal flux values were determined and the distribution of these values in components of the electric machine were computed.…”

This paper presents a comparison of an AC radial flux interior permanent magnet (IPM) motor with the distributed winding (DW) and concentrated winding (CW). From time to time, manufacturers of electric vehicles change the design of electric motors, such changes may include changing the DW into CW and vice versa. A change to the winding in a radial permanent magnet synchronous motor may lead to a change in motor parameters during motor operation and /or change in the distribution of the magnetic field and thermal circuit of the electrical machine. The electromagnetic analysis, efficiency map, mechanical stress, and thermal analysis of the machine with the DW and CW are presented in this paper. This article describes the advantages and disadvantages of selected stator winding designs and helps understand manufacturers' designers how the DW and CW play a key role in achieving the designed motor's operational parameters such as continuous performance. Analyzing the performance of both machines will help identify their advantages and disadvantages with regard to thermal phenomena, magnetic field and operational parameters of the presented IPM prototypes. Both prototypes are based on commonly used topologies such as 12/8 (slot/pole) and 30/8 (slot/pole) IPM motors consisting of magnets arranged in a V-shape. The AC IPM motor was designed for an 80 kW propulsion system to achieve 170 N•m at a base speed of 4 500 rpm. Modern CAD tools are utilized throughout the numerical computations based on 2-D finite element methods. Selected test data are used to verify and validate the accuracy of finite element models.

“…Determination of heat distribution inside the machine is a difficult task that requires a large amount of calculation. Addressing this problem can be done by finite difference numerical methods [1], [2], finite element numerical methods [3], [4], [5] or by using equivalent thermal schemes (global analysis of machine) [6], [7]. All previously mentioned approaches require knowledge of thermal parameters of the machine components.…”

Abstract. This paper presents a mathematical model and numerical simulation results for heat transfer analysis that takes place at the frame level of a rotating electric machines provided with longitudinal cooling fins. For this purpose a relatively complex three-dimensional model is used, numerical treatable with affordable hardware and software resources. The frameenvironment convective heat transfer process is considered. The frame is cooled by forced convection in two cases: the thermal radiation heat transfer is taken into account and without considering it. Numerical simulation results reveal the heat transfer pathways from the frame to the environment, and allow assessment of important parameters in designing the machine's cooling.

“…The main component is the electromagnetic one, which is designed for the electromagnetic performance assessment of the electrical machines by using precise analytical methods and FEA [7,8]. By applying the thermal unit, a 3D lumped thermal circuit can be built up automatically, enabling the user to determine the steady state and transient thermal characteristics of the machine taken into the study [32][33][34][35][36][37]. The third module, named Lab, is a special toolbox for combined electromagnetic and thermal simulations, which can ease the modeling and optimization tasks of the designers [38][39][40][41].…”

This paper deals with the simulation of a permanent magnet synchronous machine (PMSM) to be developed for driving a scroll compressor of a vehicle air conditioning system. The simulations were needed for the verification of the pre-sizing and for the electromagnetic behavior analysis of the PMSM. These were performed by using the ANSYS Motor-CAD software. All the obtained results emphasized that the pre-sizing of the PMSM was performed correctly, and the designed electrical machine can fulfill all the prescribed requirements. To highlight the superiority of the chosen surface-mounted PMSM topology, a comparative study was performed for four PMSMs having the same stator but different rotor topologies having the same quantity of permanent magnets. The study revealed that the PMSM with permanent magnets on its rotor surface is the best-fitting variant for the foreseen application. By intensively using the ANSYS Motor-CAD software, the authors appreciated that this product is a very useful tool in the hands of the designers not only in evaluating the machine’s computed geometry (by checking its correctness and feasibility), but also in its in-depth electromagnetic analysis and in calculating its parameters of interest.
