Greartisan DC 12V 120RPM Turbo Worm Geared Motor High Torque Turbine Worm Gear Box Reduction Motor 6mm Shaft JSX40-370

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!

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.

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.

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.
