Modernization of the VSVEM-1140 electro-mechatronic system for testing theasynchronous motors

The article is devoted to the description of practical experience in testing the alternating current electric machines. The results of combining thecapabilities of digital systems for collecting and processing information with a powerful electromechanical system are presented. Itis the combination of two systems of different purposes that enables creating the state-of-the art diagnostic installations combined into one electro-mechatronic system. Practical results of electric machine tests contain clear explanations of fundamental principles and provide acomprehensive assessment of the conditionof electric machines. They use methods of direct charging the electric machines with the possibility of recuperation of electric energy during tests. Thermal state of electrical machine nodes is monitoredusing the thermal forecasting technologies. Both the methods for various types of tests and means for their implementation are described in detail. This article is intended for engineers involved in designing, manufacturing and testing the electric machines.
