    Motor arrived well. But I can not find the right ratio; it seems to be about 3.5 and not 5.18 as if there was a gear blocked internally. I have tested the motor with Arduino and Ramps 1.4. Incredible and strange. All my purchases on Banggood were excellent in price and quality. This is the first time that I have problems.

    The gearbox is truly well mechanically made. Silent operation (given it is driven with correct driver and correct current setting on the driver :) I used the Pololu - DRV8825, 12V and current limited to 1.3A with potentiometer on the Pololu board (driver board setting to do 1/32 micro-stepping) used this Arduino sketch to drive the driver https://github.com/impexeris/A4988-and-Arduino/blob/master/cntrSpeedDirDRV8825TimerPWM.ino When motor runs fingers are not able to stop the shaft and there is

    The gearbox is a planetary gearbox with 3 satellites, in particular the number of teeth for the solar gear (z1) is 17 while the number of teeh on the 'corona' (z3) is 46; hence the ratio between the input and outout shaft is 3.7:1 (z1+z3)/z1

    This is a powerful little gearmotor. Long leads and east mounting. The planetary looks good. I cleaned everything packed it with fresh grease and now it is running my rotary axis on my minimill.

    Good product, however it may have damaged during transport due to the packaging. The gear doesn't turn smoothly, it stops on random places, like there is small particles inside. Wouldn't buy again.

    It is pitty the the voltage rating is about 3 volt. Perhaps a voltage rating of 5 volt would be better as 5v power supplies are more current.

    Il motoriduttore è arrivato ben imballato e si presenta bene e senza gioco! Bene!

    Dieser Stepper Motror ist bestens geeignet für direkt angetriebene Extruder (3D-Drucker) oder für die Z-Achse. Qualität ist i.O.
