Vector space as an area of the operation risks characteristics for asynchronous electric machines

Abstract

The article is written in terms of topological theory for the asynchronous electric machine (AEM). During operation the vector space properties of AEM are changed under the influence of operational aging and operational damage. The information about its current properties is used to assess the AEM routine operating condition and the risks of the operational integrity loss. The authors analyze the vector spaces of the stator symmetric three–phase winding and the AEM rotor 9–phase cage. Their common working area is discovered, which serves as a communication channel for a stator and a rotor. A Working area operational testing methodology is described. Absolute and relative measures of risk for AEM operational integrity loss are introduced.
