Abstract:
A stepper motor can be looked upon as a digital electromagnetic device
where each pulse input results in a discrete output (i.e. a definite angle of shaft
rotation). There are different modes to drive stepper motor such as wave drive
mode, full step drive mode, half step drive mode and micro stepping. In wave
drive mode, one phase of stator windings is energized at a time. In full step
drive mode, two phases are energized simultaneously. Half stepping can be
achieved by alternating between the wave drive and full drive and the step
angle is reduced by half. Finally micro stepping is obtained by deliberately
making two phases currents unequal in the full drive mode.
In this project, we aim to study the application of stepper motor in Smart
Dish using Adriano.
