Product Code : SCL-EELE-13315
Indian Lab Suppliers supplies the DC Motor Speed Control Trainer (Product ID: 13315) as part of its electronics engineering lab equipment range. It is a closed-loop speed control system built around a small permanent-magnet DC motor, with an eddy current brake for loading.
Quick Answer
The 12 V, 4 W PMDC motor (0–2500 rpm typical) sits in a separate see-through cabinet with an electronic tachogenerator for feedback and a non-contact eddy current brake for variable load. Actual speed is measured independently by a photodiode reading a slotted disc and a frequency counter, shown on a 4-digit rpm display; a built-in 3½-digit DVM reads signal voltages. Students measure how forward-path gain changes steady-state error, time constant and load-disturbance rejection, and find the motor transfer function and tachogenerator characteristic. It runs on 230 V ±10%, 50 Hz with 50 cm stackable 4 mm patch cords. Keep fingers away from the rotating disc.
