Let's give you an example.

that's a simple 12V 87Amp 1600 RPM motor. Maybe good enough for a 3 wheel trike (if the motor suddenly decides to work or if i rebuild it)
Just as an example - that motor on the controller's output
with 2 car batteries in series equaling 24 volt 750Amp DC input
(a ballpark of car battery amps)
could you do something for a motor like that?
(no shame if you say it's over your head.)
Myself, i'm getting a larger motor this weekend so the controller wouldn't be much use to me. but it'd be a good test for you to see if you can figure it out.
edit:
LINK this is a simple PWM controller for a small fan.
