So you need an Arduino stepper motor for your next project? Check the best available stepper motors fitting Arduino shields and drivers, plus a list of available kits.

Stepper motors are becoming mandatory for controlling movement in the physical world. Almost any robotics project requires one, along with a microcontroller. Their main advantages include the ease of use, their affordable prices, rounding few tens of dollars (or even less), and the simple operations involved.

These qualities make stepper motors ideal for getting started in robotic projects. However, their versatility allows their application for more advanced users.  But which one should you choose? Are all of them alike? To find out more continue reading.

If you haven’t got the proper Arduino, please take a look here:

Best Arduino Stepper Motors How Does a Stepper Motor Work?

Stepper motors are Direct Current motors, mostly known as DC motors, which move in discrete steps. This means that they rotate one step at the time. The rotation is a result of the magnetic current induced by an electrical current, which is generated inside of the motor.

Stepper motors have multiple coils organized in phases. The steps for the motion are computer controlled. They can achieve precise positioning, speed control, and low-speed torque with high precision through the steps.

The motors have 48 outer and inner teeth. In order to magnetize the inner teeth, the motors contain 8 separated coils. Four steps will be created by the magnetic field that results from the electrical current. Multiplying the number of teeth (48) by the steps (4), the motors get 192 steps per rotation, equivalent to a rotation of 1.8° per step. This type of stepper motor is the most common, known for the full steps (200 steps/rotation).

Due to their unique design, stepper motors can be used with a high degree of accuracy without requiring any feedback mechanism. The motors could in principle be moved mechanically, but for real tasks, a driver must be included in the system. Hence, the system consists of a microcontroller driving the order, which will result in an electric current in the driver. This controls both the step and the direction of the motor, which will generate a magnetic current driven by the electric discharge. Discrete steps will result in a smooth and controlled position, ideal for high precision tasks, such as 3D printing.

Best Arduino Stepper Motors Which Stepper Motors are Available

There are two types of stepper motors: unipolar and bipolar. For each motor, different circuits are required.

Unipolar stepper: This motor works with one winding with a center tap per phase. Each section of the winding is switched on according to the desired direction of the magnetic field. The magnetic pole can be reversed without switching the direction of the current. Note that these motors are less available in the market compared with bipolar ones, given that their efficiency is only up to 50%. This is a result of the unipolar steppers having twice as much wire as they can use at one time.

Bipolar steppers: In these motors, there is only one winding per phase. A more complex circuit is required to reverse the magnetic pole, given that the current in the winding needs to be reversed. This means that it usually needs an H bridge arrangement. Yet, bipolar motors are more powerful than unipolar ones. They are recommended for more sophisticated tasks, and also are more expensive than the former.

So… which one should I use?

Here’s a brief comparison to help you choose the correct motor for your project. When following a guided project, you will certainly get detailed information on the components required.

Pro Bipolar: Unipolar motors will only use half of the winding at a given time, while bipolar uses the entire winding. The last one uses a bidirectional current flow. As a consequence, torque will be greater in bipolar motors than in a unipolar one. Additionally, the thinner coil wire in unipolar motors implies that more wire is needed. this last factor increases the resistance in the motor. Its implication is higher power consumption.

Pro Unipolar: In favor of the unipolar motors, these motors are simpler to use and so require an easier circuit. Additionally, they are cheaper and will use less of your driving board’s capacity.

Therefore, according to your current proficiency level and budget you should decide for one or the other. Affordable motors of each type are readily available, as you can get our budget selection below. Additionally, forums and communities online can offer great support overcoming your beginner doubts.

Best Arduino Stepper Motors Software

Image of Best Arduino Stepper Motors: Software

To run your stepper motor you will need to code your Arduino through the open-source Arduino IDE environment. It runs on Windows, Mac OS X, and Linux. The environment is written in Java. This is required to control the steps per revolution, speed, and directionality (backward and forward) and the step type, such as single, double or micro steps. Micro-steps refer to a movement in a fraction of a step, which results in a smoother motion between steps.

Fortunately, both the kits readily available for purchase and those aimed to be customized and DIY, have provided extensive codes online. Yet, you will need to change the parameters to your specific motor’s needs. For more advanced users, optimizing the code is also a possibility. However, some coding experienced (or patience to learn on the run) is required. As a common place to start, refer to the communities’ suggested set up and customize according to your needs.

Motors

Estimating the project’s holding torque should give you an idea of which motor you will need, given that the decisive factor when looking for a motor should be the specific project requirements. Hence, our list is organized according to the holding torque of each motor. The holding torque refers to the torque that the motor will produce when the motor is at rest and the rated current is applied to the winding.

More variations of these models are available online, but we stuck with the low-budget ones. Note that the unipolar motors are less common than their bipolar counterparts. Once selecting a suitable motor for your project, you should look for an appropriate driver. For a thorough look into stepper motors and their drivers, check this comprehensive Arduino forum post.
