I have a Neptune Apex aquarium controller that, among other things, output 0-10V DC to control things like motors. I want to get a low variable speed motor that can go from an almost 0 to 10 or 20 RPM in response to the controller output. My optimal speed is around 7.5 RPM but I would like to be able to adjust the speed as needed. This motor would not require high torque at all but it would be continues duty, runny 24/7 365
Moving a slider bar in the controller’s software changes its voltage output. This is not intended to be an accurate speed control.
My first thought would be a stepper motor and one or more boards but a servo motor or even a regular motor might work as well and be simpler.
What would you suggest that I thing about using to get this done?
