Otherwise, the motor will burn out. 5.Motor storage: -- Storage temperature: 0℃ - 40℃; -- Storage humidity: 15% -90% RH; -- Avoid placing in high temperature, high humidity and corrosive gases. 6.Motor use temperature: 0℃ - 70℃ Review: Value for money - Solid construction, good torque without drawing excessive amps (fine on a 2 amp supply) and is reasonably priced for a geared motor. Review: Good replacement for Merkel-Korff motor - For years we've used a small gear motor, originally made by Globe and later Barber-Coleman, now Merkel-Korff. When they raised their; minimum buy to 150 pieces we went searching for a replacement and this Greartisan motor works great at a lot less in cost to us as well as no minimum buy. We tested this motor in our engineering printer for hours at a time and it performed flawlessly. Very happy to have found it. Now after several years of shipping this motor as a replacement for worn out Merkel-Korff motors we are seeing similar longevity to the M-K motors. They are standing the test of time. ## Features - 【ALL-METAL GEARS】: High-temperature resistance, high abrasion resistance, strong load capacity, sturdy and durable, effectively protect the gear box motor body. - 【PURE COPPER WIRE CORE ROTOR】: With precision winding technology, the geared motor power instant increased by 30%. - 【D SHAPED OUTPUT SHAFT】: Using high hardness steel, good toughness, impact resistance, the quality of the bearing and the service life of the gear motor are improved, extremely durable. - 【POSITIVE-NEGATIVE ROTATION】: You also can adjust the speed, but the motor speed can only be reduced, can not be raised. Low noise and high torque, such as 10rpm can drive 15 kilograms. - 【RELIABLE GURANTEE】: Any quality issues, we promise 100% unconditional return service. If you need other voltage and rpm, please feel free to contact us! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072R5QSRG | | Brand | Greartisan | | Brand Name | Greartisan | | Customer Reviews | 4.8 out of 5 stars 68 Reviews | | Horsepower | 200 Watts | | Item Dimensions W x H | 36W x 33H millimeters | | Manufacturer | Greartisan | | Material Type | Metal | | Model | Greartisan | | Model Name | gear | | Model name | gear | | Part Number | Greartisan | | Product dimensions | 36W x 33H millimeters | | Speed | 200 RPM | | UPC | 766330626999 | | Unit Count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** Greartisan - **Horsepower:** 200 Watts - **Model name:** gear - **Speed:** 200 RPM - **Voltage:** 12 Volts ## Images ![DC 12V 200RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Image 1](https://m.media-amazon.com/images/I/61Evn9b4D3L.jpg) ![DC 12V 200RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Image 2](https://m.media-amazon.com/images/I/71QaGQzmmvL.jpg) ![DC 12V 200RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Image 3](https://m.media-amazon.com/images/I/61gesAjy+oL.jpg) ![DC 12V 200RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Image 4](https://m.media-amazon.com/images/I/61ubRus7FOL.jpg) ![DC 12V 200RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Image 5](https://m.media-amazon.com/images/I/61cAWt7KS5L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How much weight can this motor lift if it was used for a "mini" garage door opener? Door would be 50"x30". Approximately 30lbs** A: The maximum torque this motor could produce is approximately 0.67 lb-in peak at close to stall. The stated speed 120 RPM is assumed to be a no-load value. Using a more reasonable operating 60% of these values, the motor may approximately produce 0.4 lb-in at 90 RPM. The power available from this unit is approximately .426 watts. You want to lift a 30 lb door 30 (?) inches in an assumed 10 seconds which is approximately 10 watts. So what you are asking is will a 0.43 watt motor power a 10 watt requirement. The answer is no. (The preceding power requirement calculation does not address any added wattage requirement due to friction or drive efficiency losses which would increase the "no" to a "HELL NO") **Q: Can I use a 12V 1A adapter with this motor?** A: Depends on your application. I got 20 RPM motor: no load at 12V ~100mA. No load start-up < 200mA. If you put intermittent heavy load, then i measure > 2A. I think stall test was nearly 4A. **Q: Do these leak grease from the gear box?** A: Nope no sign of any grease leaking out yet **Q: If this motor is used as a wind turbine generator, will it output 12v at 200rpm?** A: I used mine as a hand crank phone charger that charged a battery pack. I worked great and the output will vary based on your load and speed, so it will probably have a lower voltage than 12v at 200RPM. You'll want to put it through a full bridge rectifier with a capacitor in parallel to produce a DC voltage, however the diodes and capacitor will also drop your voltage. The battery pack I was using was only around 6 to 7 volts DC, also the gearing in the motor is really high so for a wind turbine you would probably have to help start the blades to get them to spin. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value for money *by J***. on 30 July 2026* Solid construction, good torque without drawing excessive amps (fine on a 2 amp supply) and is reasonably priced for a geared motor. ### ⭐⭐⭐⭐⭐ Good replacement for Merkel-Korff motor *by R***S on 11 September 2018* For years we've used a small gear motor, originally made by Globe and later Barber-Coleman, now Merkel-Korff.
