About this item

  • New micro 2-phase 4-wire 4mm stepper motor,with planetary gearbox(the outer diameter is only 4.25MM), and its planetary gears cannot be seen clearly with the naked eye. It can be distinguished by using an enlarged mirror. The entire metal slide is also very precise and stable.Connection of motor, gearbox and metal slide,all using laser welding points, is very precise and sturdy.
  • The motor drives the precise skewed lever to move the metal slider up and down.
  • The brackets are basically made of metal.
  • The spindle is made of ultra-fine precision ball bearings.
  • The difference between model A and B is just the length of the cable. The stepper motor, reducer, and metal slide are all the same.


Specifications:
Slider stroke: about 12mm
Motor phase resistance: about 14.4 ohms
Weight: 3g
Note:
The lead foot of this stepper motor is relatively fragile. It will break if pressed hard. Buyer friends should be very careful when using it.
Manual measurement, with small error. Please check size in detail before purchase.
Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution.
Package Includes: 1pcs

bought a handful and tested one on an arduino (no special driver, straight from the pins) and it works great.

The image is labeled incorrectly. Swapping the B+ & B- pins gets it moving, as the traced image I’ve attached shows.Fun little linear stepper!I recommend shutting off power to the pins any time it doesn’t need to move, or it’ll just build up heat. This design holds position with no power applied.I’ve used this with an Arduino Uno, straight off pins 2,3,4,5 and the example sketches “Constant Speed” and “Bounce” from the default stepper library.

So far I haven't been able to make this move. It just gets hot. The windings still measure 14Ω so I'll assume I haven't burned it out. I'm using an A4988 step-stick that is also new to me, so it might be operator error...I'd give it one more star if it came packaged better and with a bit of printed data in the package.

Like one of the other reviews mentions, it just gets hot, doesn't ever turn.

I bought this for a mini pin plotter I built. It worked great... for ten minutes, just enough to print "Hello World" the next print it failed and when I tested the motor it was dead.
