Stepper motor introduction

“

- Stepper motors are one of the types of motors that are available to work with your Arduino Projects. Instead of rotating the shaft at a constant speed stepper motors move in discreet steps using controllers to apply voltage to the motor. Stepper motors 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. One of the common applications for a stepper motor is a 3D printer. The advantage of stepper motors is that you can achieve a much higher precision movement because they provide accurate at a fixed angle movement. There are two common model of stepper motors. Unipolar and bipolar. Which differ in how the internal coils are wired. For unipolar stepper motors it has five wires and four coils. All of the common coil wires are tied together internally and brought out as a fifth wire. The center connection used as the power connection. They are called unipolar steppers because power always come in…
