Even though the use of DC servomotors is a convenient solution for most customers, from some modem analysis criteria points of view, this type of drive system has a low reliability and a greater impact on the environment, compared to AC servomotors. From this class of AC servomotors, high behaviors, in such an application, have stepper motors and electronically commutated motor （brushless DC）. That is why, analysis in this paper, balances these two classes of AC servomotors. The systems performed are analyzed in Matlab/Simulink and PowerSim environments.展开更多
