Further the stepper motor has the advantage of having a holding torque.Steppers are able hold their position when they are not moving. With a stepper motor you can “step” exactly a given angle. Driver circuit & a microcontroller are needed to control the speed & direction of a stepper. Stepper motors are not like simple DC motors and cannot be driven by providing just DC voltage. This characteristic makes it very suitable for digital interfaces integrates with a microcontroller. Since the stepper motor does move in discreet movement, we can say that a stepper motor is actually a digital motor. In the example below you may notice that there are 4 distinct steps for the rotor to make a complete 360 degree rotation. The stepper motor moves is distinct steps during its rotation. This is the most complete guide about this module.Ī digital electric motor that moves one step at a time and each step is defined by a step angle.
