Stepper Motors

The two most important factors in selecting a stepper motor are the torque and the current requirements. Choose a motor that can develop enough torque to overcome the frictional and inertial loads at the highest stepping rate needed. The current rating is a maximum continuous duty rating. You can certainly operate a motor at somewhat less than the rated current to reduce motor heating or to get away with a smaller driver for cost reasons. You may also overdrive a stepper motor if adequate heat sinking is available or if the operate to idle ratio (duty cycle) is relatively low and the driver produces a "current cutback at idle" capability.
