Hello everyone, I am fairly new to electronics so if you can bear with me I would highly appreciate the help.
I am looking to power a stepper motor from the arduino motor shield and im not sure what kind of power supply I need or even if the motors I have would work with that shield.
Holding Torque: 48N.cm Type: Hybrid Phase: 2 Current / Phase: 2.5A Step Angle(degrees): 1.8Â° http://www.aliexpress.com/store/product/Free-Shipping-NEMA-17HS-5425-stepper-motor-length-48mm-holding-torque-48N-cm/707369_475731728.html
It seems i cannot run this motor from the arduino shield because it requires higher amps per phase than the board can supply. Is there any way around this problem ? Could I just run it with lower amperage? or do i need to get another stepper or driver?
External power: In previous projects I was powering the arduino from a wall adapter rated 1000mA 3-12 V. I assume this is not enough for the stepper, what should I get instead? and how exactly should I power it?
In the final scenario I would like to have a potentiometer controlling the speed of rotation of the stepper, spinning only in one direction.
