DC Position Control System Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13324
Indian Lab Suppliers supplies the DC Position Control System (Product ID: 13324) as part of its electronics engineering lab equipment range. It is a real electromechanical angular position control system with a geared DC motor, servo-potentiometer error detector and tachogenerator feedback.
Quick Answer
A 12 V, 1 A armature-controlled DC gear motor (50 rpm) turns the output shaft through a reduction gear set, and two 360° servo potentiometers compare reference and output angle on dials with 1° resolution. A tachogenerator (about 2 V per 1000 rpm) gives positive or negative velocity feedback. Because the real response is slow, a microprocessor-based capture card stores the step response in RAM and replays it on an ordinary measuring oscilloscope. Students study step response, rise time, overshoot and steady-state error as forward gain and velocity feedback change, and see real effects such as saturation, dead zone and backlash. It runs on 220 V ±10%, 50 Hz with a 3½-digit DVM, built-in step input and supplies; an oscilloscope is needed and not included. Keep fingers clear of the gears.

Frequently Asked Questions
Why is a waveform capture card included?
The real step response is too slow to see on a normal oscilloscope, so it is stored and replayed.
What does velocity feedback change?
Damping, overshoot and stability of the position loop.
What resolution do the dials have?
1°.
