Universal Motor Speed Control with Power Supply & Motor Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12890
Indian Lab Suppliers supplies the Universal Motor Speed Control with Power Supply & Motor (Product ID: 12890) as part of its electronics engineering lab equipment range. It controls the speed of a small universal (AC/DC series-wound) motor with SCR and TRIAC circuits, and the motor is supplied on the board.
Quick Answer
Four controllers are built: a half-wave SCR controller without feedback, the same with feedback, a half-wave skip-cycling version that gives high torque at low speed, and a full-wave TRIAC controller with DIAC triggering, where the hysteresis effect is shown and reduced by gate slaving. Two potentiometers and two capacitors set the firing angle, and a snubber across the TRIAC improves its dv/dt rating and reduces RFI. The controller handles universal motors up to 1/4 HP; the motor supplied is stated as 1/12 HP or less, so please confirm its rating at quotation. The board runs from 230 V ±10%, 50 Hz mains and weighs about 3 kg.

Frequently Asked Questions
Why can a universal motor run on AC and DC?
Its field and armature are in series, so both reverse together and torque keeps the same direction.
What does feedback add?
It holds speed steadier as the load changes.
Is the motor included?
Yes, a universal motor of 1/12 HP or less is fitted.
