Makermotor 10mm 2-Flat Shaft 12V DC Reversible Electric Gear Motor 50 RPM

I used this little gear motor to electrify a hoist I had made for my mobility scooter. All of the manufactured hoists were meant to lift the whole scooter. Due to space in the rear of my Jeep Patriot I have to load the scooter in pieces. I can't lift the rear axle, battery, or main deck. So I made up a handy little hoist that fit in my hitch receiver, using the lightest boat trailer winch I could find. HOWEVER, this was beginning to cause problems in my right shoulder from cranking.Then, I stumbled on this little gear-motor while surfing Amazon. After some pondering & calculating the torque requirements, carefully reading specs, etc. & a visit to Wondermotor's website to confirm specs.,I ordered one. I've finished the hoist & used it a few weeks & it is working fine.I have no idea what this motor is actually for but it seems to be a quality, well made device. It's up to the purchaser to decide if it is appropriate for his need.But I'm completely happy with the outcome of my project because it meets my need for something that I just couldn't buy anywhere.Just one little warning... The motor is powerful for its' size but the driven gear is white plastic (maybe Nylon) Don't use it where the torque load is greater than its' rating.UPDATE: May 22, 2016... OK, I've been using my home made hoist with this gearmotor for over a year now & it's doing the job perfect. A few weeks ago, I took the side cover off to inspect that plastic gear. It's doing GREAT! I lubed it with some multi-purpose grease just because I thought it might be a good idea.I was looking at the owner's manual on line for a Fiamma camp trailer awning & the motor on the electric version looks EXACTLY like this one.

This is a very good low RPM and high torque DC motor. I'm using it to power a large photographic turntable using #25 roller chain and it's awesome. It comes up to speed quickly and its speed is easily controlled by a PWM controller. I've only been using it for a couple of weeks but I feel it's bulletproof.

4 months plastic gear stripped , used very light duty. Purchased. Gearmotor 7 years ago still in service ( plastic gears not good) NOT HAPPY

I used this to motorize my manual awningPros: , It works great, lots of torque, its quietCons: A little pricey, Placement of mounting holes made installation a little difficult for my application

Overall, this motor has a configuration that makes it easy to integrate into a mechanical design. The one issue I have is the location where the wiring exits the motor body. This location is 180 degrees from the side of the motor the gearbox projects from the most. This requires allowing at least an additional half an inch of clearance from the motor centerline on this side (top in the image) that would not be required if the wiring termination were located at another point on the circumference. The ideal location from the perspective of minimizing package dimensions would be to place it on the same side as the gearbox, in that location the electrical termination would not be a package dimension constraint to any significant degree as it now is.

50RPM, works well with PWM control from an Arduino through a motor driver; forward and reverse. The shaft is a flattened rod so you can attach a pulley or something to it and there's no way it can slip. I printed a 3L V-belt pulley that slips on perfectly.Two things to be aware of:1. if you have the motor running at full or near full speed and then stop it in an instant, it jumps. Literally, off the table. Might not be a problem if it's securely fastened to something. My code ramps down the speed over the course of a second.2. there are three threaded holes for mounting it. But the plate you mount it on can really only be about 1/4" thick and still have the shaft stick through the mount enough to attached a pulley.

Pro:Very quietPlenty of torqueThe motor being perpendicular to the shaft makes the installation more compactCon:None so farBe sure to refer to Wondermotor's website for a drawing of the motor and it's mount. Including a copy of it with the motor probably wouldn't be a bad idea.

What can be said? It does it's job! Well built sturdy little thing. Great housing, made well. Love it! :)
