When it comes to selecting the right stepper motor for your application, understanding the NEMA stepper motor size chart is essential NEMA (National Electrical Manufacturers Association) provides standardized dimensions for stepper motors to ensure compatibility and interchangeability across different manufacturers By referring to the NEMA stepper motor size chart, you can easily determine the physical dimensions and mounting requirements of a stepper motor.
The NEMA stepper motor size chart categorizes stepper motors into different frame sizes, with each size denoted by a number The most common NEMA sizes for stepper motors are NEMA 17, NEMA 23, NEMA 34, and NEMA 42 The number in the NEMA designation corresponds to the faceplate dimensions of the motor in the unit of tenths of an inch For example, a NEMA 17 motor has a faceplate that measures 1.7 inches by 1.7 inches.
Let’s take a closer look at the characteristics of each NEMA stepper motor size:
1 NEMA 17:
– Faceplate dimensions: 1.7 inches by 1.7 inches
– Holding torque: 44 to 93 oz-in
– Typically used in smaller applications such as 3D printers, CNC machines, and robotics
2 NEMA 23:
– Faceplate dimensions: 2.3 inches by 2.3 inches
– Holding torque: 76 to 300 oz-in
– Commonly found in medium-sized applications like laser cutters, engraving machines, and small CNC routers
3 NEMA 34:
– Faceplate dimensions: 3.4 inches by 3.4 inches
– Holding torque: 275 to 1300 oz-in
– Suitable for larger applications such as industrial automation, packaging machinery, and large CNC milling machines

– Faceplate dimensions: 4.2 inches by 4.2 inches
– Holding torque: 750 to 3500 oz-in
– Used in heavy-duty applications like large CNC plasma cutters, CNC routers for stone cutting, and industrial automation equipment
By referring to the NEMA stepper motor size chart, you can easily identify the right size of stepper motor for your specific application In addition to the physical dimensions, the NEMA size also provides valuable information about the motor’s torque output, which is crucial for determining its performance capabilities.
When selecting a stepper motor, it’s important to consider not only the size but also other factors such as step angle, step accuracy, current rating, and operating voltage These specifications will vary depending on the specific requirements of your application, so it’s important to carefully evaluate each parameter to ensure optimal performance.
In addition to the NEMA stepper motor size chart, you may also come across other designations such as “17HS4401” or “23HS5628” when shopping for stepper motors These alphanumeric codes provide additional information about the motor, such as the stack length, coil resistance, and other technical details While these codes can be helpful for identifying a specific motor model, the NEMA size is still the standard reference point for comparing different stepper motors.
When installing a stepper motor, it’s important to pay attention to the mounting requirements specified in the NEMA size chart Different NEMA sizes may have different mounting hole patterns and shaft dimensions, so it’s essential to ensure proper alignment and compatibility with your equipment.
In conclusion, the NEMA stepper motor size chart is a valuable resource for selecting the right stepper motor for your application By understanding the different NEMA sizes and their corresponding characteristics, you can make an informed decision when choosing a stepper motor for your project Whether you’re working on a small-scale DIY project or a large industrial application, the NEMA stepper motor size chart will help you find the perfect motor for your needs.
