You might try telling that to bobamosfet....before you ask, it’s ok to have a supply rated for more than the load, because a load (the motor) only takes what it needs. The transformer can’t / won’t force 2A into a 200mA motor.

Do they have HVAC stores there? 24VAC is the voltage used in most every heating or air conitioner system on it's controls. https://www.google.com/search?clien...hUKEwitibOCy5PpAhVll3IEHS6vDIoQ4dUDCAs&uact=5I'm from Philippines and i can't find any 24v DC bell transformers only 12v DC ones, I guess i'll just have to make do with 12v DC, Thanks djsfantasi and MaxheadRoom for answering my question
I just pick any bridge rectifier with specifications that exceeds the output of the transformer and just solder it on right? No need for a capacitor since my only load is dc motor, could i moderate the speed with a potentiometer?Rectifying AC is connecting two wires from the transformer to a bridge rectifier and taking two wires from the other or DC terminals of a bridge rectifier to your load. Since your load is a motor, you may not need filtering, which is just a capacitor across the DC terminals.

he controllers then use a po
I have done my research and i'm now ready to start this project, I thought that I would build my own PWM controller so I could soak all the knowledge i can. Thanks for you help everyone! i hope that I don't run into any troubles! if I do then I'll just have to do more research or bump this thread and hope that someone can explain answers to my questions in the future! Thanks again!I was on my way to bed when I posted that. Controlling speed of a motor with a pot can’t be done. Motor current is more than any pot can handle. Maybe a rheostat, but they’re expensive
Motors are controlled typically with PWM, pulse width modulation. The controllers then use a pot. ESC stands for electronic speed control. You can also search for a motor controller. Modules are available.
The module must be able to control the motor voltage. Plus, it’s current capacity must be able to handle the motors stall current.
(Motors have two current ratings. Stall or Startup current and Run current. The latter is the lower number)
Some controllers have inputs to control direction as well.
For starters, here you go!I have done my research and i'm now ready to start this project, I thought that I would build my own PWM controller so I could soak all the knowledge i can.
