There are three stepping modes of a stepper motor. The stepping mode refers to the pattern of sequence in which stator coils are energized.
1. Wave drive (One phase ON at a time)
2. Full drive (Two phase ON at a time)
3. Half drive (One and two phase ON at a time)
1. Wave drive :
In wave drive stepping mode only one phase is energized at a time.
2. Full Drive :
In full drive, two phases are energized at a time.
3. Half Drive :
In half drive, alternately one and two phases are energized. This increases the resolution of the motor.
