Our take on the 1/3/5Packs Nema17 Stepper motor 34mm 0.28Nm 40oz.in 2PH 4Wire for 3D Printer/CNC

A NEMA 17 frame stepper motor with a 34mm body, rated at 0.28 Nm (40 oz.in) holding torque, two phases and four wires. The short body suits tight builds where a standard 40mm motor will not fit, such as compact 3D printer extruders and small CNC axes. It trades some torque for that length, so it fits light loads better than heavy ones. Buyers pick it for the standard 42mm mounting pattern and the common 4-wire bipolar wiring.

Pros
  • Standard NEMA 17 42mm face and mounting holes
  • Short 34mm body saves space in tight frames
  • 0.28 Nm holding torque is enough for light axes and extruders
  • Four-wire bipolar wiring works with common A4988 and TMC drivers
  • Sold in single, three and five packs for multi-axis builds
Cons
  • Less torque than the common 40mm NEMA 17 motors
  • No datasheet details such as current rating or step angle given
  • Shaft type and connector are not specified
  • Not suited to heavy loads or high-speed axes

Questions and answers

What does 0.28 Nm and 40 oz.in mean here?
It is the holding torque: the turning force the motor holds when powered but not moving. 0.28 Nm equals about 40 oz.in, which is modest for a NEMA 17 and suits light loads.
Will it fit a standard NEMA 17 mount?
Yes. NEMA 17 means a 42mm square face with 31mm hole spacing, so it bolts to the same brackets as other NEMA 17 motors. Only the body length differs at 34mm.
How do I wire a 4-wire bipolar motor?
The four wires form two coils, A+ and A- on one, B+ and B- on the other. Pair them with a multimeter by finding the two wires that show continuity, then set the driver current for the motor.
Is it good for a 3D printer extruder?
It works for direct-drive extruders and light bowden setups, and the short body helps on compact toolheads. Check that the torque and current suit your extruder before buying.
What is the difference between the 1, 3 and 5 packs?
They are the same motor in different quantities. A single motor suits one axis or a spare; multi-packs suit builds that need several matched motors.
Does it come with a pulley, cable or driver?
The listing describes the motor only. Assume you need to supply your own pulley, wiring and driver board unless the seller states otherwise.
