How to Choose a NEMA 17 Stepper Motor
Choosing the right NEMA 17 stepper motor requires more than matching the standard 42 mm frame. Engineers should consider motor body length, step angle, holding torque, phase current, shaft configuration and transmission requirements.
Motor Body Length
NEMA 17 motors share the same nominal 42 mm frame size, while motor body length varies between models. Shorter motors are suitable for space-limited equipment, while longer motor bodies are commonly selected when higher holding torque is required.
0.9° or 1.8° Step Angle
A 1.8° NEMA 17 stepper motor provides 200 full steps per revolution. A 0.9° NEMA 17 stepper motor provides 400 full steps per revolution and is suitable for applications requiring finer positioning increments.
Holding Torque
Holding torque varies by motor body length and winding configuration. Current NEMA 17 models in this series range from approximately 1.8 kg·cm to 8.7 kg·cm (18–85 N·cm), with longer-body models available for higher holding torque requirements.
Phase Current
Different winding configurations are available with phase current options of approximately 0.5–2.5 A per phase. The selected winding should be matched to the stepper driver and operating requirements.
Shaft Configuration
Available shaft configurations include single shaft, dual shaft, D-shaft, custom shaft dimensions and integrated lead screw designs.
Gearbox or Encoder
A gearbox can be added where higher output torque and lower output speed are required. An encoder can be integrated where position feedback or closed-loop operation is needed.

NEMA 17 Stepper Motor FAQ
What is a NEMA 17 stepper motor?
A NEMA 17 stepper motor uses the NEMA 17 mechanical frame standard, commonly with an approximately 42 mm × 42 mm mounting face. The designation defines the frame size rather than one fixed motor length, current or torque value.
What size is a NEMA 17 stepper motor?
The mounting face is approximately 42 mm × 42 mm. Motor body length varies between models according to construction, winding and torque requirements.
Are NEMA 17 motors available in both 0.9° and 1.8° versions?
Yes. A 1.8° NEMA 17 stepper motor provides 200 full steps per revolution, while a 0.9° version provides 400 full steps per revolution.
How much holding torque does a NEMA 17 stepper motor provide?
Holding torque depends on motor body length and winding configuration. Current NEMA 17 models in this series range from approximately 1.8 to 8.7 kg·cm, or about 18 to 85 N·cm.
Can a NEMA 17 stepper motor use a gearbox?
Yes. NEMA 17 stepper motors can be combined with planetary, worm or parallel shaft gearboxes for applications requiring higher output torque, lower output speed or a different mechanical transmission layout.
Can a NEMA 17 stepper motor use an encoder?
Yes. Encoder options can be integrated with NEMA 17 stepper motors for position feedback and closed-loop motion-control applications.
What shaft options are available for NEMA 17 stepper motors?
Available options include single shaft, dual shaft, D-shaft, custom shaft dimensions and integrated lead screw configurations.
Can NEMA 17 stepper motors be customized?
Yes. Motor body length, step angle, winding, phase current, shaft dimensions, cable length, connector type, lead screw, gearbox and encoder configurations can be customized according to OEM requirements.
