Mine has a fair bit of play which is concerning alot more than 20arc.... unfortunately I've got no choice but to use it. The box was damaged but packaged OK. I'd ask for a replacement but I couldn't wait for it...

Sembra faccia il suo dovere con precisione. Vediamo se mantiene le caratteristiche nel tempo. Per ora sono soddisfatto.

As indicated in the specs the gear has some backlash. Otherwise a cheap and powerful solution.

Stepperonline products come with a 1 year warranty as stated on their website, but they will claim faulty products are NOT refundable outside 6 months. Stepperonline are a fraudulent company do NOT deal with them.

I am using this as an aid for dividing / indexing objects at certain angles. I eventually want to make some hand wheels with 50 graduation marks. Also need to mark, discs for 180 degrees. You can only drive this motor at less than 100 Hz, in single stepping mode. You can do half step, quarter step etc. that helps a bit with the smoothness / lack of vibration, but takes more pulses.

I'm using it with a laser displacement scanning head to find the centers of dimples on a golf ball. Thanks to the wobble of how I mounted the golf ball to the stepper motor, I have a nice sinusoidal output that helps with measuring the number of full steps needed for a full revolution. For my particular motor, I just computed that I need 19910 full steps for a full 360 degree revolution by doing a correlation on the measured data. If the motor moves at 1.8 degrees per step, that means the motor moved 19910 * 1.8 degrees = 35,838 degrees while the output shaft moved 360 degrees. 35,838 degrees / 360 degrees = 99.55. So, I think that means the ratio of my gearbox is actually 99.55, not 99.05 as stated in the description. Just an FYI for anyone who might find that useful. (It threw my scan results off by about 1.8 degrees per scan line using the wrong ratio which adds up quickly since I wasn't starting back at 0 each time, meaning the error accumulated for each line...)

100 nano meters per step in my rig. Precision! This is perfect for my application.

This worked as expected and I am happy with the purchase. Has a lot of torque which means very slow rotation.

The motor works great and the output shaft spins slowly as expected with such a high gear ratio. Only two concerns which prevented a 5/5 star review are that the motor did not have the standard 4 pin connector (just had 4 loose wires) and the motor is not compatible with a standard Nema 17 mount due to the gearbox attached to the front.

Using this to make a custom lab instrument. With a driver that can micro-step this unit provides an incredible 7.8nm/step resolution. There is minimal backlash in the gearbox.
