Comparative Analysis of Conventional Methods for Braking a Three-phase Induction Motor and Research on Efficient Combinations of Methods for Efficient Braking Process

This paper discusses the errors in braking an electric motor in different conventional operating modes for positioning with a screw lead mechanism. The focus of this document is on the error caused by the duration of the braking process. First, three electric braking modes are considered, namely self-excited braking using capacitors, magnetic braking and DC injection braking, and classical connection schemes are suggested. There are three combinations of the modes, mentioned above to increase the accuracy of the system. Research has been carried out to determine which stopping mode is the most accurate. Simulations were then performed in Simulink by using models with the same parameters to establish the truth of the research by analysing the value of the errors. Finally, a conclusion was made about the effectiveness of the used methods and applications of classical regimes in positioning systems.
