Im looking at buying a 0-30V 0-5A variable regulated power supply to play around with dc motors ranging from 3v to 12v and varying amps. I plan to connect them directly without using mosfets, transistors or switches of any kind, just looking to vary the speed of them for use with 3D printed models.
My question is, can I do this successfully without needing a fly-back/snubber diode or without overloading the capacitors in the power supply? Im only new to electronics and have read a lot about needing fly-back diodes when dealing with mosfets and inductive loads but cant seem to get a good answer when it comes to directly using nothing but a dc motor.
Thanks in advance.
Just looked into powering the dc motors more and I was reading that a short circuit protected power supply wont work with DC motors, is this true? because every power supply i can find has that built into it.
