The scenario
Designing a reliable speed controller for a salon vacuum cleaner's universal motor using phase control.
What is in this drawing
Read the decisions behind it.
01
Using a phase-controlled TRIAC dimmer circuit for universal motor speed regulation
02
Including EMI filter and snubber for noise suppression
03
Simple potentiometer-based speed adjustment
Suitable for any small AC universal motor applications like vacuum cleaners, drills, and mixers requiring variable speed.
