DC Motor Speed Control System (PWM, SCR) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13326
Indian Lab Suppliers supplies the DC Motor Speed Control System (PWM, SCR) (Product ID: 13326) as part of its electronics engineering lab equipment range. It compares PWM and SCR controllers for open- and closed-loop speed control of a 12 V permanent-magnet DC motor.
Quick Answer
The motor (0–2000 rpm typical) sits in a separate see-through cabinet with a small generator, an electronic tachogenerator for feedback and a non-contact eddy current brake for loading. Speed is sensed by an opto-interrupter and shown on a 4-digit microcontroller rpm display; a 3½-digit DC meter reads signals. Students run each controller open- and closed-loop, with and without load, and measure timings on the motor voltage waveforms. It runs on 230 V, 50 Hz, draws about 17 VA, measures 340 x 210 x 125 mm and weighs about 3 kg. A 20 MHz dual-trace oscilloscope is needed and not included; keep the oscilloscope earthed and use isolated or differential probes for waveforms that are not ground-referenced.
