Universal Motor Speed Control Manufacturer,Supplier and Exporter in India
Product Code : EL-EELE-11248
Quick Answer: A board for controlling the speed of a universal motor of 1/12 HP or less with an SCR and a TRIAC, comparing a triac full-wave controller with a half-wave controller.
Last updated: October 2026
Key Features
Universal motor of 1/12 HP or less capacity.
SCR and TRIAC for speed control.
Full-wave triac controller demonstrating hysteresis effects improved by gate slaving.
Half-wave controller giving high torque at low speed, with skip cycling operation.
Two potentiometers, two capacitors for the firing angle, a DIAC and two diodes.
Snubber across the triac to improve dv/dt and reduce RFI; mains switch, fuse and jewel light.

About This Product
Students compare two approaches on the same motor: full-wave control with the triac, where gate slaving improves the hysteresis effects, and a half-wave version that keeps torque high at low speed by skip cycling. The capacitors and potentiometers set the firing angle of the thyristors, and the snubber circuit shows how dv/dt and radio interference are kept down. Colleges and TVET centres in Central African Republic, Venezuela, Albania, Togo, Chile and Guinea can source the Universal Motor Speed Control from Educational Lab Equipments.
Frequently Asked Questions
What motor is used on the Universal Motor Speed Control board?
A universal motor of 1/12 HP or less, controlled by an SCR and a TRIAC.
What does the snubber circuit do?
It is connected in parallel with the triac, improving the device's dv/dt and helping to reduce RFI.
