STUDY ON STAND automated electric STUDY frequency regulation electric drives, built on the principle of vector control

摘要

The invention relates to electromechanical systems and, in particular, for automation facilities of the electric power, and can be used in the educational process as a training bench for automated electric actuator for the study on the basis of an asynchronous motor with frequency vector control.; Training stand for automated electric drive is designed for smooth loading of the actuator, while expanding the functionality and efficiency of the use of the stand. The stand is further provided with a second asynchronous electric motor, articulated to a first asynchronous electric motor, a second frequency converter, which is part of the second analog-to-digital converter, a second variable potentiometer tumbler, the second emergency stop button, a second button trigger, the second contactor. A distinctive feature of the stand is the fact that as the loading machine is an asynchronous machine, the stator receives power through the inverter circuit from providing the necessary orientation points relative to the moment developed by the induction motor primary.
