Nema 17 Stepper Motor
- Nema 17 Stepper Motor with Integrated 300mm T8 Lead Screw, much stable than shaft coupling connecting
- Each phase draws current 1.68A, allowing for a holding torque of 40Ncm.
- Easy to plug: 30cm lead wire with XH2.54 connector,no soldering or peeling works.
- Frame size: 42mm*42mm*40mm. With 1.8° step angle (200 steps/revolution)
- Precisely machined full metal body, great replacement for the Z axis of prusa i3 3d printers.
Key Features
High Quality Stepper Motor
No shaft coupling needed,integrated with stepper motor and lead screw. Precisely machined full metal body, heat shrink tubing effect to prevent the wire tangled up.
Electrical Specification
Each phase draws current 1.68A. Holding torque up to 0.4Nm(56.2oz-in), low loss stators have better high speed performance.
Physical Specification
Frame Size: 42 x 42mm; Body Length: 40mm. Lead Screw Lengh:300mm. 2-phase 4-wire, 30cm lead wire with XH2.54 connector,no soldering or peeling works.
T8 Lead Screw
Lead screw mainly used in stepper motor, machine tool, and other equipment.
Lead Screw: Material: stainless steel Diameter: 8mm Pitch: 2mm
Screw Nut: Material: brass Diameter: 8mm Pitch: 2mm
Connection Notice
As a stepper motor, it should connect to a constant current or chopper driver. Connecting the motor directly to a power supply will destroy the motor.

Could not find an applicable torque vs speed plot to use for calculating force output. Limited information available on the unit.

First this is 300mm not 310mm, not to big deal for me as 300mm is just barely enough but wanted the extra 10mm for safety. Second would not work for me, not sure if these motors don't produce enough torque or what, tried many different amp settings but no matter what would not rise the print bed, actually would start lower instead of rising, if i turn the shaft with had while rising then it would go but then stop again. Thought i had a bad unit, got it replaced and same thing. Went with another brand that was 310mm shaft and works great unlike this one

The lead screws are not 310mm, I purchased two and they were 300mm measured from the top of the motor (same as in their website description). Returned...

I bought this as a replacement for the y axis on a lotmaxx shark v2. I had to reverse the polarity so that it wasn’t running the machine backwards. But it’s beefier than the stock one and less likely to overheat (which turned out NOT to be the issue with my printer, but I’m keeping it because the stock one did get relatively hot and this was a good motor for the money).

I can't attest to the bad reviews saying this thing is terrible at X or Y performance, but lead screw steppers shouldn't even be used for those axis, you dungos!

Verkäufer gibt an das die Spindel ab dem Motor 310mm lang ist. Ist aber nicht so sie beträgt 300mm und das geht nicht zurück gesendet

Works very well to replace the Anet A8 Y motor. Because it is taller at 40mm compared to 38mm from the original I had to make adjustments so it won't hit the bed. Also, you'll have to rewire it because the phases won't correspond to the ones on the Anet, basically match every color to every wire.

Disappointed with the quality control—my unit arrived with a broken cable, making it unusable right out of the box. This suggests inadequate inspection before shipping. Buyers should be prepared for potential quality issues.
