In this project, we will use the hybrid motor type. The common stepper motor type is the hybrid motor type.

The energizing of both the coils change the accuracy of the rotor from 30 degrees to 15 degrees. When both the coils are excited, the position of the rotor (in between) is shown below: The position of the rotor (moves 30 degrees), when coil B is energized is shown below: The position of the rotor, when coil A is energized is shown below: It means that the rotor moves to the position with the least reluctance. After that, the coil A will energize again. The above figure signifies the step size is 30 degrees. If we trigger or energize the coil A and B, the rotor would rotate. It is done so that one pair of rotor teeth at a time can be aligned easily with the stator. It has different teeth compared to the rotor, which is four. The rotor in the stepper motor is made up of a stack of steel laminations. It is shown below:Ī stepper motor with six stator teeth can be triggered with three different DC power sources. The stepper motor can control the angular position of the rotor without a closed feedback loop.Ĭonsider a motor with six stator teeth and a rotor. Such devices are used when we require high torque popularly at low speeds. The bipolar stepper motors do not have any center tape connections. There are two leads per phase in the motor. The bipolar stepper motor consists of a single winding per phase. The Unipolar stepper motor has five leads when both the phases are joined internally. For the regular two-phase stepper motor, there are six leads per phase. There are three leads per phase in the motor. The Unipolar stepper motor consists of one winding that operates with a center tap per phase. The Stepper is categorized into two types, which are listed below:Įach type possesses a different circuit, but the coding is similar. It has a simple, accurate open-loop system. We can also hold the position of the motor at any step during rotation. These coils are negatively and positively charged in a sequence, which makes the shaft to move in forward and backward in little steps.

Each driver circuit has a potentiometer to control the maximum output current, a DIP switch to switch the step resolution, easy to control step rate.

Easy and fast to step up the stepper motor project, especially for 3D printer project.

The A4988 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ☒ A. The A4988 is a complete micro stepping motor driver with built-in translator for easy operation.

We use high-quality SPF 3.5mm pitch terminal for stepper motor connection, the male header side has screw socket, which can provide reliable connection for the whole project. This stepper Motor driver Arduino shield had three built-in A4988 stepper motor driver IC, which allows you to drive three different stepper motors independently. Now you have the chance to add only 1USD to get NOA brand SMDuino board!
