9. Abstract
The requirement for high torque, speed and position control of the electric drive, led to
the rapid development of servomotors and the servomotor systems. Servomotors are new
technology motors which incorporate feedback deivce and with the help of the servodrive
system they can ensure precision movement. Usually they are used in automation control
systems.
Generally speaking this diplomatic paper is a presentation on operating principles,
characteristics and main applications of servomotors and servosystems.
The first chapter provides a general introduction to the servomotors, main parts, basic
characteristics, advantages and disadvantages, categories and selection criteria for the
applications.
The second chapter provides an analysis of the basic types of electric servomotors such as
induction motors, direct current motors, permanent magnet synchronous motors, hybrid
servos, R/C servos and digital servos.
The third chapter refers to the servomotor systems, the functional diagram, the feedback
devices, the cost, the servo amplifiers and DC - AC motors servodrive systems.
The fourth chapter refers to the application areas of the servomotors and generally of the
servosystems. Servomotors offered to motion control systems the possibility for parallel
control of velocity and position with great accuracy. This makes them suitable for a wide
range of industrial applications. In this chapter we analyze several such examples in order
to fully understand their function.
