I am slightly confused about what the current ratings for stepper motor drivers are referring to. The DRV8825 high current stepper motor driver is the one i plan on using,
IT specifies that it is rated for 1.5a per phase 2.2a per phase with additional cooling elements, so does that mean in a 2 phase stepper motor is rated for 3a or up to 4.4a, with additional heatsink, per motor???
The reason i ask is i am trying to run this stepper motor, https://www.pololu.com/product/1478 but i want to make sure i dont burn up the motor. I am just confused on what exactly the specifications on the stepper motor driver are telling me and what i need to be looking for when buying a motor driver to contol the motor i need. i am brand new to arduino so any input is helpful thanks.
