How do I run 3 stepper motor on one Arduino UNO? What kind of driver is needed for various Stepper motor?
Most probably it’ll be either 4 wire or 5/6 wire. Or in other words it’ll be either unipolar or bipolar stepper motor.
Even though you can drive any stepper motor using either of those, still it’s always better to check the datasheet of the driver circuit and reference from the wiring diagrams in the internet.
Since you need to drive 3 stepper motors you can either get 3 different driver units of same kind (one driver unit for each motor) or get some kind of 3 axis CNC shield/controller that will hold all 3 driver circuits in one board and also fit easily on top of your arduino without making a mess of wire mesh.
Depending on the NEMA Rating of your stepper motor you need to check for the maximum currents per pole required for driving your stepper and make sure the driver which you’re using is capable of providing atleast twice of the total current, and also the source is capable enough to provide that amount of current.
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.
Stepping angle is adjustable( rang in 18°±5%）， 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.
