Greartisan DC 12V 30RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Centric Output Shaft 37Mm Diameter Gearbox Review

Just received the PEMENOL Motor Speed Controller. Hooked it up to a 30V 10 A DC power supply to check it out. Powered up fine when I got the power supply hooked up. The LED display is easy to read. The unit output is switched by the control knob by pushing it in. There's an LED above the knob to indicate on or off. The knob has smooth indents as you turn it, indicating the PW percentage on the LED display. It goes from 0 to 100. Don't know what the PWM frequency is. I didn't hook it up to my…

Nice little motors for the price.They are strong enough to move my 4kg robot along at at decent speed.My only issue is that the 3 motors I have bought vary a lot in terms of rotation speed at the same PWM setting.

This motor works great. I have a old rc P-51 that parts are hard to find for so instead of taking a chance of breaking something I decided to turn it into a display with the propeller turning and it works great. The poles can be reversed it turns CW but I needed it to turn CCW so just swap the poles. You can definitely hear the motor running but it’s nothing overpowering

I bought this to make a rock tumbler for my wife. This motor has worked amazingly well. It's been able to handle turning several pounds of rock continuously for days without a single hiccup.

The motor probably had a short and when power was applied simply drew maximum current and just sat there. Buy at your own risk.

I previously reported how I liked the motor but the rotation direction was not as shown. After studying the detail drawing I now understand. The drawing shows the shaft rotation direction is shown from the REAR. This seems quite ridiculous. The shaft rotation should be shown with the shaft in display.

It's a bit noisy in video since it's sitting on my workshop wood surface, but when installed on roof, the noise barely noticeable . I installed the LED's in the eyes which powers one side from the motor. For the wires not to twist, i am using a bearing. Couldn't be happier with this motor.

I needed a small electric motor with low RPMs and lots of touque to run a home made fish feeder. It fit the project prefectly. The overall quality of this product is very good. I would definitely purchase the again for future projects.

Used these in my x-mass animatronics this year instead of windshield wiper motors which I normally use. They held up very well and had the torque required when given a power supply with sufficient amps.

I used two of these 50rpm motors in tandem to run a home made spit rotisserie. I cooked two 10lbs chickens continuously for 3 hours and they did not hesitate.

Great lil motor tons of torque an not loud at all its been running for a few days with out issue.def a good buy for the price!

I bought the 20 RPM , 12 volt motor to use in a Cauldron Creep Halloween prop I made. This motor was going to run the rotating pot stirring stick. The motor works fine, moves at a great rate of speed, and is quite powerful. But, it is really loud. So loud that even with my cackling witch sound effect playing it could still be heard. Due to the loudness I decided to order a different style of motor and will not be using this motor in my prop.

This thing is a beefy hunk of metal. Make no mistake either, it is very loud and the vibrations generated from the motor can be felt in neighboring rooms.

Running great for about 15 or 20 min. Then stalled and burned up. The speed control worked fine and was ok as was power supply (12Vx2A) - but neither had current limiting.

These are advertised as high torque great reduction motors. They are great reduction and the quality seems good but they have to be the weakest motors I've ever held. I doubt they will work for my application.

This motor has all the specs I needed. Works great, really good price. Will check this brand again, next time I need a small DC motor.

My conversion was off on the metric system size was an 1/8 of an inch to big all the way around. Sorry for ordering the wrong size

Good small 12 volt DC motor.Powerful for size, difficult to stall only about 30 MA @12 Volts when my project is at max load.

This motor hooks up easy and does run but is not capable of giving the torque it projects. Have it hooked up to an rc small truck and will not move the truck in reverse. I also don't believe it is giving 550 rpm as intended, i tried to return it to revain but it was past my return date due to not having tried it until recently. Any advice.

Worked lovely,thought it was smaller then the picture but still worked.id like to find one thats smaller that has faster rpm and torque power if possible
