Asynchronní kroužkový motor a jeho využití

Abstract

The work is aimed at analyzing the performance characteristics of ring asynchronous motors with a focus on the effects of changes in the rotor resistance. The thesis contains a basic set of operating characteristics measurements whose results are used to determine the energy balance of the machine and to construct Circle diagram. Furthermore, there is dedicated space measuring motor when changing the rotor resistance. The measurement results are complemented with theoretical calculations . The conclusion is devoted to a deeper analysis of the stator current and torque characteristics machinery. The analysis is performed to compare the results obtained from the measurement , calculation of equivalent circuit and also by reading the Circle diagram.
