Stepper Motor pulling excessive load (3-4A).
2.0 USB powering Arduino board. ADA board with soldered headers stacked on top. ADA VIN power jumper removed and input power attached to variable power supply and set at 13VDC fixed. I have two momentary switches, one to move the motor forward (left) and one to move it backwards (right). They are inputs into pins 2 and 4 respectively. The stepper motor have 4 wires; Black: A+, Green: A-, Red: B+, Blue: B- connected into ADA M3(Green & Black), M4(Blue & Red) with ground terminal open.
I was surprised to not see any voltage info on my stepper motor but this was my logic when planning. The Arduino and ADA boards and stepper to be powered with 12VDC. The stepper motor instructions showed 0.95A Rated current with 1.8deg step angle and 2 phases. I calculated required power= rated current(.95) X 12VDC = 11.4Watts, or about 1A. I believe the ADA board can run 4.5 - 13.5 VDC up 1.2 amps.
I wonder if I need a stepper motor drive board capable of higher voltage (18-24VDC) and that would in turn lower my current. However I could also have issue with connection method or code and wanted to get some peer feedback.
Thanks in advance.
