I have a 12 volt worm gear motor
and I need to be abel to control it’s speed. I have it hooked up to a PWM control board and when I try to control the speed at low RPM the motor has a jerky motion and sound like it is continuously starting and stoping and quit noisy.
This will not work for me as my project requires as quiet an operation as possible and also a smooth transition of speed and power.
I have looked around and found that using a potentiometer is out of the question due to the high amps. This brings me to Rheostats, or at least I think it does. With that in mind I figured it would be easy to find what I needed, I was wrong.
I can fix, repair, or build most anything I put my mind to but when it comes to electricity I am way out of my league.
I need to know what size of rheostat I need for this job or if there is something better that would be great also. Below is the volt/amp information on this motor.
VOLTAGE - 12DC I am using a standard 12 volt car battery as a power source.
AMPS - 3.0 at no load.
AMPS - 6.0 at continuous operation.
AMPS - Momentary for peak operation or starting under load.
