Abstract: The use of a permanent magnet synchronous machines (PMSMs) to achieve high performance and high energy efficiency in modern industrial technology has increased rapidly in recent decades. Similarly, the demand for PMSMs in hazardous locations has been increasing as well. This work focuses on the safe operation of PMSMs in hazardous locations, as it undergoes through a series of mechanical, electrical and thermal tests. These tests methods ensure that no hot surfaces, electrical arcs or sparks occur during normal or possible failure operation. In addition, it ensures that there are no possible failure conditions in all inner and outer parts of the PMSMs that can lead to high energy which may be responsible for ignition. The PMSM installed in hazardous areas need to have protection against the possibility of ignition. Therefore, the thermal protection of the PMSM using PTC thermistors sensors are tested so that the PMSM stops operating in case of higher thermal heating of stator winding. Different influencing input quantities from the instruments used for measurement in the test bench are studied and the uncertainty is analysed. While determining the efficiency of the machines the final measurement uncertainty of the test bench is examined and presented with "Guide to the Expression of Uncertainty in Measurement" (GUM) procedure. Besides the testing of the PMSM, this work, therefore, deals mainly with problems concerning the demagnetization of the PM during abnormal operating condition of PMSM using FEM simulation.
