Tiivistelmä
The goal of this study is to evaluate and follow the development of the multi-axis servo and drive systems. Systems were compared from several manufacturers for this study regarding their technical properties and solutions focusing on power electronics. Selected multi-axis servo systems were ordered and dissembled for closer observation. The power electronics components were listed and compared between each other. The datasheets of the components were obtained from the manufacturer websites.
In the beginning of the study the basic operation and principles of multi-axis servo drives are introduced. The benefits of multi-axis drive systems and common applications are presented. Next different system implementations are introduced and the different functions of the different modules are explained. After the theory, this study focuses on the results from the disassembled modules and processes the discovered information.
The conclusions focus on defining the limiting rules of designing multi-axis servo systems to guide and support future product planning. Such instructions concern dimensioning of the IGBT modules, distribution of common DC bus capacitance and addiotionally control electronics performance. The collected data has been added as an appendix of this study along with the reverse engineered power elec-tronics schematics from the selected manufacturers that were ordered for closer inspection.
