   Fast Modelling, Sizing and Mapping Techniques for Permanent Magnet and Externally Excited Axial Flux Machines
By Lukas KIRZINGER, Dieter GERLING, Martin BRÜLL [View]
[Download]

Abstract: Axial flux machines (AFM) are a new trendwithin automotive powertrain development. Their speciallayout requires high demands in finite element method(FEM) simulation. Typically three dimensional (3D) modelslead to high complexity as well as high simulation time.Paired with the innovative topology of externally excitedaxial flux machine (AFEEM), this problem intensifies withthe additional control possibilities. Therefore, to ensure fastdevelopement processes, different techniques are exploredwithin this paper. For the simplification of the simulation atwo (2D) and two and a half dimensional (2.5D) modellingapproach are shown for both machine types. To getcomparable designs and performances, sizing equations arederived. In addition, a fast mapping procedure is providedto also have access to the full speed range of the builtelectric machine. Finally, the resulting data is comparedto 3D FEM results and the speed up of the total processis shown.

   Implementation of new cooling configurations in electric motors via CFD and CHT modeling
By Marco MINAZZATO, Giacomo PERSICO, Alessandro CASTAGNINI, Giulio SECONDO [View]

Abstract: This paper presents a useful method for implementing new cooling configurations for electric motors using CFD and CHT analysis. The tuning and validation process through experimental tests for the current setup is shown, a new configuration is analyzed with the validated model and the results obtained are presented.

   Methods to Reduce the Errors in the d- and q-Inductance Estimation of a SynRM by Considering the Residual Magnetism
By Vasken KETCHEDJIAN, André HASPEL, Philipp MARX, Jörg ROTH-STIELOW [View]
[Download]

Abstract: When the current dependent direct and quadrature inductances of a synchronous reluctance machineare calculated using measurement results, the estimated inductance values can drastically deviate from the actual ones for small current values. This paper presents an investigation of these deviations and introduces two methods to minimize the estimation errors, which consider the effects of the residual magnetism. Experimental results are also presented for a 12kW reluctance machine.

   Review of Advances in Cooling Schemes for Yokeless and Segmented Armature (YASA) Axial Flux Motors
By Gokhan CAKAL, Bulent SARLIOGLU [View]
[Download]

Abstract: This technical review evaluates advanced cooling techniques for the yokeless and segmented armature (YASA) axial flux motors. Due to high torque density and efficiency advantage, YASA motors are getting more and more attention; however, their thermal management still remains a challenge. Therefore, this paper highlights the latest developments in cooling technology for YASA motors.
