“…Two variants of the multi-flux barriers rotor, namely, axially, and transversally laminated can be seen in Figure 2. Besides the radial flux topologies, recently a concept for an axial flux SynRM was proposed [7]. Finally, the last evolution step for further enhancing the capabilities of these type of machines was to insert permanent magnets in their rotor structure [8].…”

In this paper a side-by-side comparison between synchronous reluctance machines (SynRMs) with concentrated and distributed windings is performed. The characteristics, parameters, and the installation space of a permanent magnet synchronous machine (PMSM) with concentrated windings used in a 13 V automotive cooling fan system (CFMs) are used as requirements and specifications. For that, eight SynRMs with different stator and rotor topologies are investigated and optimized by means of FE-based electromagnetic optimization. Knowing the challenges associated with the development of mechanically stable SynRM rotor structures, for two selected cross-sections in view of being prototyped, designs checks are performed to ensure robust operation at up to two times the required operating speed. The simulated results were verified by means of measurements performed using two different types of loading systems, i.e., with the real ventilator and using a DC machine as a load. Based on this, the relative differences between all three motor technologies in terms of important quantities (e.g., torque-speed characteristic, torque ripple, efficiency, power factor and ultimately the size) are highlighted.

“…Effectiveness of the magnetic core fan cooling such that the insulating layer lifespan, which minimizes the dissipative nature of the permanent magnets, is safeguarded. 52 The effect of integrated air-cooling of the interior rotor was investigated to evaluate the thermal utilization of PMSM. The air-cooling system of the rotor was designed to dissipate the heat.…”

This paper gives a brief review of advanced cooling methods and applications to the permanent magnet synchronous motors (PMSMs), as well as investigates the cooling systems design problem for PMSM systems. Heat sources and losses together with analytical and practical analyses are described. Next, the temperature distribution and its influence on the PMSM is investigated using simulation results. The main part of the paper includes a review of the proposed cooling methods that will release the requirement of heat transfer of the PMSM. The finite element methods (FEM) are applied using the AnSys CFD software to obtain high accuracy thermal model of the PMSM system. The new developed forced air-cooling methods are given in details, which enable to effectively redistribute the temperature and heat transfer increasing the efficiency of the PMSM machine. Examples of CFD simulation are outlined to illustrate the effectiveness and benefits of the strategies developed.

Efficiency, power density and cost play an important role in motors used in low-power industrial applications. In today's world, where the importance of energy efficiency and compact structure is increasing day by day, the Axial Flux Synchronous Reluctance Motor (AF-SynRM) design, which is a unique motor with no copper loss in its rotor and compact with its axial structure, has been compared with the Axial Flux-Induction Motor (AF-IM) with the same stator structure. Figure A. Rotor parts of two motors (AF-SynRM and AF-IM) with the same stator structure.Purpose: In this study, in two motors with the same stator structure and dimensions; In AF-IM and AF-SynRM, only the rotor part has been changed and the change in output parameters has been examined. Theory and Methods:In the preliminary study of the designs, the motor dimensions were calculated analytically and modeled with the 3D Finite Element Method (FEM). To optimize the saliency ratio, which is the most important factor affecting AF-SynRM performance, a Genetic Algorithm (GA) based optimization was made and the rotor geometry was changed. Results:In comparison, the outer diameter, inner diameter and stator parameters are the same, and the motor efficiency has been increased proportionally by 8.53% with only rotor change, and it has been increased from IE3 to IE4 standards. At full load, the AF-SynRM produced 23.2% more power than the AF-IM Conclusion: Considering the total losses, costs and efficiency values, the AF-SynRM design will be an alternative to the AF-IM compared with reference. In future studies, experimental comparison of AF-SynRM, which goes through production processes, with AF-IM will also be possible. In addition, designs of AF-SynRM with permanent magnets can also be designed and the comparison procedure can be repeated. Highlights• Motor Design. • Axial Flux.• Finite Element Method.
