Abstract: The Finite Element Method (FEM) is a prominent analysis approach. Although it is applicable for simulation and optimization of electrical machines, FEM is a very time-consuming technique. One of the approaches to shorten the optimization runtime is the use of surrogate models instead of FEM. In this paper, the design and optimization of an outer rotor permanent magnet synchronous motor for a hybrid vehicle are investigated. Response surface methodology (RSM) with four input variables is integrated with a sequential quadratic programming algorithm for optimization. Before the optimization, the performance of the surrogate model in the prediction of untried points is validated. Finally, the optimal motor is simulated by FEM to verify the results of RSM-based optimization, and the outputs of both models are compared.Keywords: response surface surrogate method, outer rotor permanent magnet synchronous motor, sequential quadratic programming optimizationPublished in DKUM: 05.12.2023; Views: 512; Downloads: 4 Full text (683,42 KB)This document has many files!

Abstract: This paper deals with the implementation of a measurement system, capable of performing real-time data acquisition and control, and allows the performance analysis of electric drives used for electric vehicle propulsion. For applying the mechanical load on the shaft of the tested motor three different test bench configurations with different power and speed ranges can be used. The main objective of the measurement system is to perform routine performance tests and road simulation tests (in terms of driving cycles) of an electric drive. It provides a research environment for analysis, investigation and study of electric drives and control strategies.Keywords: measurement system, test bench, electric machines, electric vehicles, permanent magnet synchronous motorPublished in DKUM: 04.12.2023; Views: 383; Downloads: 27 Full text (18,06 MB)This document has many files!

Abstract: This paper presents the method for determining losses and efficiency of small axial flux permanent magnet synchronous motor with surface mounted permanent magnets and double external rotor by using measurements. Losses and efficiency are calculated by using measured electrical input power and mechanical output power. The characteristics obtained by the measurements are in good agreement with analytically calculated results and the results obtained by the finite element method.Keywords: losses, efficiency, axial flux permanent magnet synchronous motor, measurementPublished in DKUM: 10.07.2015; Views: 2220; Downloads: 90 Link to full text
