This is related to another post I made but different enough to ask afresh.
12vdc 2.0amp SMPS.
1.0 amp 1900rpm@12vdc permanent magnet DC motor
I'm looking at motor controllers in the catalog I'll order the motor from. They are kinda pricy and I don't need any other adjustments except speed. RPM/VDC will be set and never moved much outside of a narrow range.
As an experiment, since I'm using a power supply dedicated to just this motor, I tried a common 110vac dimmer switch on the input of the SMPS.
Running a .50amp muffin fan it worked exactly as I might have hoped.
Is there anything wrong with this form of motor control for this low voltage low amperage purpose? It's so simple and seemingly elegant.
