A Stepper Motor Application in Smart Dish

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.
