Course detail

Electrical Servodrives

FSI-GES-KAcad. year: 2010/2011

The subject provides students with the knowledge of basic problems of electric servodrives and their role in driving production machines and equipment. It concerns with defining basic requirements regarding static and dynamic characteristics of servomechanisms, explaning principles of activities of the most important components of electric servo mechanisms, methodology of the design of the most frequently used feedback circuits (position loop, speed feedback, current feedback, position servomechanism with subordinated current and speed loop, dynamic submission of position loop, communication between numeric control system and machine drives), and the description of the interaction with the inertial load at servomechanisms.
