Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time.
With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.
Stepper Motor Operation
In this theory section, we’ll get a quick reminder about how stepper motor works. Stepper motors work in very specific way, a standard stepper motor will have two or more coils that charge and discharge when electricity is allowed to flow through them. The animation below illustrates that.
When the coils are charged and discharged in a specific pattern (usually sequentially), it creates an electromagnetic attraction between the coil and the motor. When this occurs fast enough it makes the stepper motor turn, and we get the movement you see above.
