Kohree 12V DC Gear Motor 30RPM Small High Torque Electric Motor 37mm GearBox

Excellent little motor for the price. I used this for a motorized camera slider and it works well. It has quite a bit of torque - enough that you cannot stop it from turning with your fingers.It is a DC motor so it runs slower with less voltage. It ran at about 1/2 speed when I ran it with 4 AA batteries (6v). It has been running fine with hours of use at a time.If you are looking to get an slow speed or a variable speed motor, getting the right controller and motor together can be tricky. I used the "RioRand Upgraded 6V-90V 15A DC Motor Pump Speed Controller" with this motor and it works fine - on 6V or 12V. This allows you to control the speed from super slow to the full 30 RPM (when running it on 12v). And super slow up to 15RPM on 6V.It has two terminals at the back that you can clip wires onto or solder them on, if you reverse the wires the motor turns the other way.It also ships from within the USA so you don't have to wait weeks for this one to come from China. Overall very pleased with this purchase.

I intend to use it for motorizing open/close of curtains (will use arduino + raspberry to drive it) in my living room. I got this specific product because of the high torque and reasonable price. Initial (prototype) testing proved it was the right choice. I stopped at the hardware store and picked up some 4mm screws and will attach the motor to the correct brackets for proper operation. Also got a 6mm shaft attachment and pulley to complete the critical (moving) parts of the project. Overall I would recommend this product, I might need to get a 2nd motor for other home automation ideas.

The torque developed by the motor was less than the specified. The specified torque was 120 N-cm. With the winch I built, the motor stalled at about 80 N-cm. I have two bearing in my design that are Bronze bushing and I do not have the friction factor for the bearings but I doubt that it is high enough to explain the difference. When designing for this motor application I recommend using 60 N-cm to be safe.

The 60 rpm motor speed works very well for remote operation of a Levolor blind tilter using the following additional parts:URBEST® 37mm DC Geared Motor Mounting Bracket Holder + 6mm Hex CouplingHot !

I purchased this small motor to power a home-made device that had a 12 V DC power supply and required a relatively slow high torque motor, The NexTrox Mini fit these requirements perfectly and performed as I had hoped. It seems to generate very high torque and the DC powers allows me to easily vary the speed. Excellent product.

Works well. Easy to mount. I use it to scare pigeons away from the ground area below our bird feeders. Attached a 30" length of plastic hoseso that it swings in a 60" circle, keeping pigeons away. Motor is driven by a driver using a random timing circuit. Running on 9V power supply.

worked well for about 10 days then it went from30 rpms to about 6 rpms and needed help to get started

the mounting hole striped out on some motors but otherwise it is good motor.
