## Description

desertcart.com: CQRobot 270:1 Metal DC Geared-Down Motor 37Dx72.5L mm 6V/12V, with 64 CPR Encoder and Bracket. 6V-3W-20RPM-40 kg.cm(556 oz.in), 12V-6W-40RPM-70 kg.cm(972 oz.in), D-Shaped Output Shaft 16mm. : Industrial & Scientific

Review: Decent hobby motor with encoding capabilities. - This review is for the "CQRobot 70:1 Metal DC Geared-Down Motor 37Dx70L mm 6V/12V, with 64 CPR Encoder and Bracket. 6V-5W-75RPM-15 kg.cm(208 oz.in), 12V-10W-150RPM-27 kg.cm(375 oz.in), D-Shaped Output Shaft 16mm.." I ordered this due to the built-in gear reduction. Overall the motor is pretty stable with no apparent back slop. The encoder also seems to show pretty accurate measurement pulses and seems consistent with the simple test I set up. For the most part, it passed so I'm going to be using it to move a bracket into position. I can use other motors for this, but I like the gear reduction... slow for my application is better as there is no room for a worm gear. It functions as listed, and is an acceptable value for what it does. Worthy of consideration imho.
Review: Works - I tested this using the sketch in the Wiki listed in the product description. The first few declarations are all smashed together so you have to do a little copy and paste to get it to run properly, but it does do what it says. It will give you a running output from the motor encoder to the Arduino serial monitor. You can unplug the motor (as I did in the screen shot) and see the changes in the encoder output as the motor slows down after losing power. In order to actually do something with this, you'll need a motor controller board. There is plenty of online tutorials to guide you through that if you are new to this. Be certain to heed the warning about keeping mounting screws to 3mm of penetration. Lots of power in a small package. Works as advertised-recommended.

### ⭐⭐⭐ The shaft is not 16mm as shown in decription. It is 6mm
*by P***S on February 28, 2026*

The shaft diameter is incorrect on this description and caused me to select the incorrect interfacing hardware. The motor itself is fine.
