Explosion-protected electrical Drive Systems

Working Group 3.63


The tasks of working group “Explosion Protected Electrical Drive Systems“ comprise testing and assessment of electrical drives and complete drive systems as well as protection equipment required for safe operation of explosion protected electrical machines (ATEX and IECEx) including research relating to this range of topics.
Here, another aspect is the thermal evaluation of enclosures with built-in components such as control units used in potentially explosive atmospheres.
Another important focus is put on new research topics concerning all aspects of electrical drive technology performed in cooperation with universities and companies.
Furthermore, technical guidance for users of explosion protected drives is another element in the range of tasks of this working group. For detailled information concerning our range of tasks please refer to the respective websites.

Abstract: The use of permanent magnet synchronous machines to achieve high performance and high efficiency in the modern motor and generator industries has increased rapidly in
recent years. The existing efficiency determining methods and standards do not however consider measurement uncertainties during loss and efficiency calculations of such machines. In this
paper, the determination of the efficiency of permanent magnet synchronous machines using direct and indirect methods is presented and the measurement uncertainty is determined
using the software called GUM Workbench "Guide to the Expression of Uncertainty in Measurement" while assessing the results of efficiency measurements.
