In this video I test a regulator or dimmer circuit for inductive loads in alternating 220V (motors generally not brushless), which works with a simple oscillator and an enabled diode that chops the alternating voltage into pulses of more or less variable duration, as a result the connected motor will have a lower average power and will turn more slowly, I will go to test it on two wheels to understand if a wheel with adjustable revolutions can be transformed into a sander or a polisher, good vision.
