    increasing the voltage usually increases the rpm and the torque.
    Mind you, if the step timing is a constant then, although the motor spends less time doing each step, the average speed should stay the same.

    Changing the average speed of the motor, then, involves making more steps per second.
    So what controls that?
  3. Generally, increasing the voltage to the stepper motor is done to provide more torque. If undertorqued, the stepper motor will not advance to the next step, ie it will not turn.
  4. Your motor should have a torque-voltage-RPM curve given by the manufacturer. Your answer is there.
