Guys I need some feedback with regards to using the LM338 5A regulator to provide the constant current requirement for my CNC machine
I am using 2 6.2V 2A per phase motors and I built the Tachus42 driver board which works well, I powered the driver and motors with 13.8V at 20A using the regulators and I saw only 4A going into the motor, allowing each winding to draw it's required 2A, I have not noticed anything that could be of concern (heating, noises, smoke, etc) but I would still like to hear from the forum members as I am sure someone has tried it before, and I am wondering why the 338 is not a normal CC source for builders on a budget.
Thanks in advance.
