GreartisanDC 12V 50RPM Turbo Worm Geared Motor High Torque Turbine Worm Gear Box Reduction Motor 6mm Shaft JSX180-370

See title.

spins at .5 rpm as advertised. Motor connections seem fragile for testing with alligator clips but worked fine for soldering.

I have several of these along with the associated "flange" that can be slid onto the shaft. I use this combination as small rotating photo tables powered by a variable voltage DC power supply. The beauty of these motors is their high gear ratios make them operate stably at even a fraction of their rated 12 volts. Lower voltage makes them rotate substantially slower, so you essentially have a variable speed turn table. The only downside is the connection tabs are so fragile you have to retrofit a connector to the motor as your first order of business. Even at a lower voltage they only draw a fraction of an amp so you could probably get variable speed with just a rheostat.

I've used several of these for various projects. They are a nice sturdy little gear motor, available in a wide range of reductions. This 35RPM version gives a LOT of torque at 12V. Easy to mount. Can run forward or reverse by changing polarity of the supply. Because it's a worm gear motor, it locks in place when not powered, so useful for anything where you want it to hold its position when idle. Will buy again when I need more.

I have a number of these that run at various speeds for different projects. I like them for their quiet, compactness and ease of use. One thing, after I solder on leads, I add a drop of epoxy or hot melt glue to the contacts, as they are tender.

the motor will not turn

Bought this little Greartisan 12v 25 RPM as well as a larger BringSmart 12 volt 16 RPM worm gear motor. I wanted to put a picture of them side by side so you could get an idea of what you're paying for. The little one was around $15 and the bigger one was around $30. That's of April 2021. I am planning to build an outdoor motorized 12-ft projection screen. I believe the Bringsmart will have enough torque for the project. I feel it is well worth the extra $15. It's easily twice the size and has wired leads as well as mounting holes on both the front and back. However if you're doing something smaller you might like the space that the Greartisan saves. The little one is roughly 3 in and the bigger one is roughly 4 and 1/2 in long. Will probably donate this little one to my son for an Arduino project or something like that. I'm forced to give it stars before I used it so I will give it five stars and then come back and adjust accordingly if necessary.

Motor after ten hours of operation at 12 v dc began smoking. Using it with a universal joint between drive shaft to precent any misalignment problems when began to over heat. Built this to use on a filament winder but failure was with no load merely driving gears on winder. No binding no problem turning with out motor. Motor just can not run long do to problems with gear box making a lot of noise from the start. Took me a while to test this due to other priorities and no ability to return. I do not suggest this motor for any voltage due to gear box. this was the third motor i have purchased sent one back due to excessive gear box grinding and noise other runs hot but use it with a fifty percent duty cycle to keep from burning up. Vendor recommended changing the power supply to five amps and you can bet if i do this I will use a fast blow fuse as a precaution as I am not sure why this is now required they indicated they would update their description on the motor in Amazon.Vendor was very supportive and recently not only sent me a refund without my requesting it, but is sending me a replacement for evaluation and I will be again updating this review based on the results. They believe that the motor gears were damaged which makes sense as i detected as previous noted oil covering the motor upon receipt. I am increasing the review ranking to three stars based on the response because there is no other way to give a five star ranking on just service as i want to evaluate the motor again.

Der Motor ist soweit ganz gut.Aber tatsächlich sehr laut und wir unter Last sehr warm.Nach einem Blick ins Getriebe fiel dann noch mangelnde Sanierung auf. Nachdem hier ordentlich machgefettet wurde, war der Motor im Betrieb brauchbar.

For years I've been hunting for a really slow-turning motor for turning a disco ball at off-grid parties (IKR?!), ideally battery-powered.Naturally, commercially available ones are easy to find - but they turn at 5rpm, which is enough to induce audience vertigo! I've even tried using low-voltage PWM units to 'dial down' the speed, but around 2 to 1.5 rpm the pulses seem to be too spaced apart to run such a motor at its rated voltage (4.5-5.0v).Finally, I took a punt on one of these.Happy days!Sure, there's a little noise from the reduction gear - but now the points of light reflected off a mirror ball revolve as steadily as the sweep-second hand of a Rolex.Best of all, it was a doddle to fabricate a little plywood case for it (see pic below) and connect a tiny 2800mAh powerbank, which will happily run it for many, many hours (I haven't tested its full capacity, but it's done easily 5hrs so far, turning a smallish mirror ball).I've no idea what other uses an excellent little DC motor like this has, but as you will have gathered I am more than happy to recommend it!
