Description

We offer D. C. Position Control System usefull in control laboratory experiment. This unit provides the students an opportunity to study and operate a practical electro-mechanical angular-position-control system. The system is built around a good quality permanent magnet armature controlled d.c. motor, speed reduction gear-set, potentiometric error detector using special **0° revolution servo potentiometers, a tachogenerator for velocity feedback and associated electronic circuits. The motor unit is housed in a separate cabinet with transparent panels for easy viewing. Interconnection with the main unit is through a standard *-pin D-type connector. Experimental work on this system would enable the students to appreciate the difference in performance between idealized systems studied in the theory classes and the systems encountered in practice.
