The Ultimate Guide To Nema Stepper Motor Size Chart
Are you tired of being confused by different sizes of stepper motors? Look no further because we have the ultimate guide to NEMA stepper motor size chart. NEMA (National Electrical Manufacturers Association) is a standard that defines the mounting dimensions of electrical equipment. In this article, we will break down the NEMA stepper motor size chart, compare different sizes, and give recommendations for your next project.
What is a Stepper Motor?
A stepper motor is a type of electric motor that rotates in small, precise steps. It is commonly used in applications that require accurate positioning, such as robotics and CNC machines. Unlike other motors, stepper motors do not require feedback to control their position. Instead, they rely on a sequence of electrical pulses to move.
Understanding NEMA Stepper Motor Size Chart
The NEMA stepper motor size chart defines the dimensions of the motor and the mounting pattern. The size of the motor is indicated by a number, such as NEMA 17 or NEMA 23. The first two numbers indicate the faceplate size in inches, while the third number indicates the stack length in inches.
For example, a NEMA 17 motor has a faceplate size of 1.7 inches and a stack length of 1.7 inches. A NEMA 23 motor has a faceplate size of 2.3 inches and a stack length of 2.3 inches. The larger the motor, the more torque it can produce.
NEMA Stepper Motor Size Chart Comparison
Here is a comparison table of the most common NEMA stepper motor sizes:
| Size | Faceplate (inches) | Stack Length (inches) | Torque (oz-in) | Price (USD) |
|---|---|---|---|---|
| NEMA 8 | 0.8 | 0.8 | 6 | 10 |
| NEMA 11 | 1.1 | 1.1 | 14 | 15 |
| NEMA 14 | 1.4 | 1.4 | 25 | 20 |
| NEMA 17 | 1.7 | 1.7 | 50 | 25 |
| NEMA 23 | 2.3 | 2.3 | 100 | 35 |
| NEMA 34 | 3.4 | 3.4 | 180 | 70 |
| NEMA 42 | 4.2 | 4.2 | 300 | 100 |
As you can see, the larger the motor, the more torque it can produce, but also the more expensive it is. It is important to choose the right size of motor for your application to avoid overpaying or underperforming.
Recommendations for NEMA Stepper Motor Size Chart
Here are our recommendations for choosing the right size of NEMA stepper motor for your application:
Small Projects
If you are working on a small project, such as a 3D printer or a small CNC machine, a NEMA 17 motor should be sufficient. It is affordable, widely available, and can produce enough torque for most small projects.
Medium Projects
If you are working on a medium-sized project, such as a larger CNC machine or a robotic arm, a NEMA 23 motor should be your choice. It is more expensive than a NEMA 17, but it can produce more torque and handle heavier loads.
Large Projects
If you are working on a large project, such as a CNC router or a large robotic arm, a NEMA 34 or NEMA 42 motor would be necessary. These motors can produce a lot of torque and handle heavy loads, but they are also the most expensive.
Conclusion
In conclusion, the NEMA stepper motor size chart is an important factor to consider when choosing a stepper motor for your project. It defines the size and mounting pattern of the motor, and the larger the motor, the more torque it can produce. We hope this guide has helped you understand the NEMA stepper motor size chart and choose the right size of motor for your application.
