Reengineering of the maintenance system of variable speed drives using multi-parameter diagnostics

The work is focused on multiparametric diagnostics, which is an important part of machine and equipment maintenance today. It deals with the use of fields such as vibrodiagnostics, electrodiagnostics, thermodiagnostics, tribodiagnostics, assembly and optical measurements as well as other diagnostic methods in order to obtain a complete picture of the monitored devices. The work also discusses the modern procedure of using multiparametric diagnostics to identify the causes of problems and define appropriate measures in the framework of maintenance. The dissertation is based specifically on the implementation of multiparametric diagnostics in the operability of drives with variable speeds and justifies the necessary reengineering of the maintenance system for these devices. The given maintenance system will clearly require a change in the inspection activity primarily in terms of quality, but certainly also quantitative verification and validation of the measured data in situ, an adequate change in the documentation processed by the manufacturer, or by the supplier, conducted by the user, etc. The work itself is based on the basic idea that if I can measure and diagnose something, then I can declare that I know something about it
