    Robust and Reliable

    Posted by Robert Dopp on Mar 21st 2021

    This product is very robust and reliable. Even at the lowest speed, the torque is very great (did not measure it, but could not stop it by hand). Is being used to drive and auger powder feeder and it works wonderfully. I CAD’ed a box to hold the electronics which you are welcome to download from Thingiverse for free. It includes the .stl as well as the gcode so you can modify it at will. You could make the box an additional 10 mm for easier insertion of the wires. The box is taped to the motor using strong Scotch Mounting Tape (

    A fantastic product and even better customer service

    Posted by Brandon Scott Livingston on Sep 18th 2020

    Ordered this looking for a compact solution to a custom weld table positioner build. Arrived in great condition, but I didn't understand how to wire it up to my digital read out to help me gain repeatable conditions for quality welds. I emailed the company asking for a more in depth print to help me achieve the desired results. Sheng called me and walked me through how this motor was not the one I need for my application, how I can achieve my desired results using a brushed motor at a significantly less expensive cost, and allowed me to return my current motor for the less expensive product. I highly recommend this motor. More importantly I highly recommend you purchase it from maker motor, due to their fantastic service and honesty.

    Runs great and is super quiet

    Posted by Gary on Feb 19th 2018

    So far so good. I'm still testing the motor, but it seems to run great. Would be nice if there was a way to access the hall sensors so I can read the rpm and control it with an arduino. I'll probably open it up and see if I can find it on the board.
