Abstract: This paper deals with determining the accuracy of measuring systems for determining the characteristics of rotating electrical machines. Efficiency classes and experimental methods for determining efficiency, are given in a standard, which has to be strictly respected. For determining the efficiency of an electrical machine, it is necessary to have a modern and accurate measurement system with sensors of high accuracy classes, which enables the user to carry out precise measurements and consequently, to determine all the characteristics of the electrical machine. This paper will be focused on torque and speed measurements.Keywords: efficiency, measuring system, electric machines, torque and rotational sensors, accuracyPublished in DKUM: 04.12.2023; Views: 529; Downloads: 54 Full text (18,06 MB)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: 56 Full text (18,06 MB)This document has many files!
