When it comes to selecting the right stepper motor for your project, one of the most important aspects to consider is the size of the motor NEMA (National Electrical Manufacturers Association) is an organization that sets standards for various electrical products, including stepper motors The NEMA stepper motor sizes chart provides a standardized way to categorize stepper motors based on their dimensions and specifications.
NEMA stepper motors are classified into different size categories, ranging from NEMA 8 to NEMA 42 The size of a stepper motor is determined by the frame size, which is the distance between the mounting holes on the motor’s faceplate The larger the frame size, the more powerful the motor tends to be Here is a breakdown of the most common NEMA stepper motor sizes:
1 NEMA 8: This is one of the smallest stepper motor sizes available It typically has a frame size of 20mm x 20mm and is used in applications that require very precise motion control in a compact space NEMA 8 stepper motors are commonly found in robotics, 3D printers, and medical devices.
2 NEMA 11: The next size up from NEMA 8 is NEMA 11, with a frame size of 28mm x 28mm These motors are slightly larger and more powerful than NEMA 8 motors, making them suitable for applications that require a bit more torque, such as small CNC machines and linear actuators.
3 NEMA 17: NEMA 17 stepper motors are one of the most popular sizes, with a frame size of 42mm x 42mm They offer a good balance between power and size, making them versatile for a wide range of applications, including 3D printers, camera sliders, and laser cutters.

5 NEMA 34: With a frame size of 86mm x 86mm, NEMA 34 stepper motors are among the largest standard sizes available These motors are capable of delivering high torque output, making them ideal for heavy-duty applications like industrial automation, large-scale robotics, and motion control systems.
6 NEMA 42: The largest stepper motor size in the NEMA standard is NEMA 42, with a frame size of 110mm x 110mm These motors are designed for applications that demand maximum torque and power, such as large-scale manufacturing equipment, heavy-duty robotic arms, and industrial machinery.
Choosing the right size stepper motor for your project is crucial to ensure optimal performance and efficiency By referencing the NEMA stepper motor sizes chart, you can easily identify the appropriate motor size based on the requirements of your application Factors to consider when selecting a stepper motor size include the physical space available for installation, the torque and speed requirements of the application, and the overall power consumption of the motor.
In addition to size, other specifications to consider when choosing a stepper motor include the holding torque, step angle, and current rating These factors can vary among different models and manufacturers, so it’s important to carefully review the datasheet for each motor to ensure compatibility with your specific needs.
Overall, the NEMA stepper motor sizes chart serves as a valuable resource for engineers, designers, and hobbyists who are looking to incorporate stepper motors into their projects By understanding the different size categories and their respective applications, you can make informed decisions when selecting the right motor for your needs.
In conclusion, the NEMA stepper motor sizes chart provides a standardized way to categorize stepper motors based on their dimensions and specifications By familiarizing yourself with the various size categories and their typical applications, you can confidently choose the right stepper motor for your project Whether you’re working on a small-scale hobby project or a large industrial application, there is a NEMA stepper motor size that meets your requirements.
