Understanding Can Stack Stepper Motors

Stepper motors are widely used in various automation and robotics applications, including CNC machines, 3D printers, and robotic arms. These motors provide precise control over the rotational movement, making them ideal for precise positioning tasks. In this article, we will focus on can stack stepper motors and guide you through the process of choosing the right one for your project.

Can stack stepper motors, also known as tin can motors, are among the most common types of stepper motors available in the market. They feature a cylindrical shape and are characterized by their construction using stacked laminations. These motors offer a cost-effective solution for many applications due to their simplicity and ease of use.

Factors to Consider when Choosing a Can Stack Stepper Motor

When selecting a can stack stepper motor for your project, several key factors come into play. Let's explore these factors to ensure you make an informed decision.

1. Evaluating Torque and Speed Requirements

The torque and speed requirements of your application are crucial considerations when choosing a can stack stepper motor. Torque determines the motor's ability to rotate a load, while speed determines the rate at which the motor can perform its tasks.

To evaluate the torque requirements, you need to determine the maximum load the motor will need to move and consider any additional factors such as friction and required acceleration. If your application requires quick movements with minimal load, a lower torque motor may suffice. However, for heavy-duty applications, you may need a motor with higher torque capabilities.

Similarly, assessing the speed requirements of your project is essential. Consider the desired rotational speed and the required precision for your application. Keep in mind that higher speeds may reduce the motor's torque output, so finding the right balance is crucial.

2. Examining Size and Mounting Options

Another critical consideration when choosing a can stack stepper motor is the size and mounting options. The physical dimensions of the motor must align with the available space in your project. Insufficient space can cause assembly issues or limit the motor's performance due to heat dissipation challenges.

Additionally, you must evaluate the mounting options provided by the motor manufacturer. Some motors may have flanges or brackets that simplify installation, while others may require additional components or custom mounting solutions. Ensuring compatibility between the motor's design and your project's requirements is essential for a successful integration.

3. Cost and Availability: A Comparative Analysis

Cost and availability play a vital role in the decision-making process. It is crucial to compare different can stack stepper motors based on their price and availability. While cost-effective options are attractive, it's important to strike a balance between affordability and quality.

Research various suppliers and manufacturers to ensure that the can stack stepper motor you choose is readily available and meets your project's specifications. Consider factors such as lead time, after-sales support, and warranty options. Durable and reliable motors may be slightly more expensive initially, but they can save you time and money in the long run.

4. Steps per Revolution: Precision Matters

The number of steps per revolution is another significant parameter to consider when selecting a can stack stepper motor. The resolution of your application depends on the motor's step angle. A small step angle (e.g., 1.8°) provides higher precision but requires more steps to complete a full revolution.

Evaluate the required accuracy and the smoothness of motion you need for your project. If precision is of utmost importance, you may need to choose a motor with a smaller step angle or even opt for a geared system.

5. Motor Power Supply and Control

Lastly, consider the power supply requirements and control options of the can stack stepper motor. Ensure that the motor voltage and current ratings match your power supply capabilities. Additionally, consider the control mechanism that best suits your project's needs.

Some can stack stepper motors come with integrated drivers, simplifying the control process. Others require separate stepper motor drivers or controllers, which offer more flexibility but require additional components.


Choosing the right can stack stepper motor for your project is crucial to ensure optimal performance and reliability. By carefully evaluating torque and speed requirements, size and mounting options, cost and availability, steps per revolution, and power supply and control mechanisms, you can make an informed decision. Don't hesitate to reach out to suppliers or experts for guidance to ensure the success of your project.
