The maximum torque this motor can generate is around 0. 67 lb- peaking on the verge of stalling It is assumed that the stated speed of 120 RPM is a no-load speed. The motor could approximately produce 0 by using a more reasonable operating 60% of these values. 4 lb- at a speed of 90 revolutions per minute This unit has a power output of approximately. 426 watts is the maximum power available. Do you want to lift a 30 pound door? ) inches in an estimated 10 seconds, equating to about 10 watts. So you're wondering if a 0 will work. A 10 watt requirement for a 43 watt motor. (The preceding power requirement calculation ignores any additional wattage required due to friction or drive efficiency losses, which would turn the "no" into a "HELL NO.")
It all depends on what you're trying to accomplish. I found a motor that spins at 20 RPM: At 12V and 100mA, there is no load. There is no need to start a load. If you apply a heavy load on a regular basis, I'll calculate it. 2A. I believe the stall test was close to 4A.
The output RPM of your electric screw driver is 200, so it depends on the speed and torque you want and/or need. You didn't say how much torque was needed to rotate the load, or even how much current was used. The motor is rated for 7 amps at 2 RPM when powered by 12 volts DC. @ 0.8 kg cm 03 amp. There is a motor that can provide 2 RPM if you want to stay at 200 RPM. @ 0. 2 kg cm 1 amp. There are also a variety of motors available with different speed ratio gear sets, depending on the speed and torque you require. In the end, you must define the torque and speed you require, then choose a motor that can deliver the speed and at least twice the torque to compensate for friction and efficiency losses. (Note; One kilogram equals one centimeter. The difference between 868 lb and 1 lb is 1. 152 kilos cm)
So far, there hasn't been any evidence of grease leaking.

I'm very dissatisfied with this purchase! It's not going to work. I took it to a battery store and tried connecting it to a 12 volt DC battery, but it didn't work. The shaft appears to be iced over. I'd return it, but the shipper would be thrown away. There was also no information in the package, only a mark on the carton; 12v DC.
Quite flimsy.
I started with small 6v DC motors that worked fine, but when I needed to upgrade to 12v, they never moved. I tried everything I could think of, including buying new 12v battles, a L298N motor driver, and a L293D IC, but nothing worked. It was extremely frustrating to work with because this was for a project with a tight deadline.
Simply put, there isn't any. What else could have gone wrong with a three-cell lipo? I'd like to return them, but I soldered wire to the mounting wire lugs, which makes them useless. br>br>I've been away from my computer for a while, and I've forgotten about your request to add additional comments to the review, so I'll do so now. I'm hoping you'll see this and be able to assist. I don't have a tool to measure torque, but I do have a new 4 cell lipo bat that I can use. With my fingers, I can stop the shaft. The robot would not move on 2 1/2 " wheels! The other 1000 rpm motors are in good shape. These were significantly more expensive than others I'd purchased, and I expected them to be superior, but they are not. I can't think of a single place where these motors could be useful! I wouldn't recommend these motors unless something changes! rk007bs@aol. com rk007bs@aol. com rk007 R Kelley, com.
In December of this year, I purchased four of these motors. This is one of the worst motors I've ever purchased. Unfortunately, by the time I got to work with them and learned how the motors worked, my return deadline had passed. So, what's the deal with the motors? br>br>
1. Pwms greater than 250 are required for motors to work.
2. As a result, if you want to slow down one motor, you won't be able to. It'll come to an end eventually.
3. The polarity of the motor changes automatically from time to time with no change. Instead of moving forward, the motor will reverse direction.
This motor does everything I expected it to do. It was purchased to turn a circular mylar graphic panel inside a larger mylar graphic panel. I used a small amount of Gorilla glue to adhere it to a metal brace that I bent into shape because it had four threaded screw holes for mounting but didn't come with any screws. br>br>It has enough torque to handle my application, and the shaft is strong enough to support my mylar piece, two plexiglas braces, and the shaft adapter.
I've now received two of these motors, both of which run at 2RPM. The first one was almost 50% off in speed. Despite the fact that it was labeled as a 2RPM motor, it was spinning at nearly 3RPM when powered by a 12-volt battery. dc power supply with a voltage of 12 volts I attempted to contact Greartisan's customer service, but Rita was uncooperative. "I ordered the 2RPM version of this motor, and while the sticker on the motor I received says 2RPM, it actually rotates at 3RPM when connected to a 12V DC power supply," I wrote in my first message. I want to replace this motor with one that runs at the proper speed. Thank you very much. "br>br>The first response I received was, "Hi Chris,br>Thanks for contacting us; we are happy to assist you!"
According to your description, this speed is within the normal range, 2 transfers have plus or minus 6% specification error, so 3 turns are normal, so 3 turns are normal. br>If you want to adjust the speed more precisely, use 3-. For fine tuning, there is a 5A governor. br>I hope this has been of assistance to you; if you have any further questions, please do not hesitate to contact me; have a pleasant day! br>Best regards,br>Ritabr>Greartisan Customer Service Team"br>br>Of course, this response was obviously incorrect, so I responded, "Hi Rita,br>Unfortunately, that math does not add up. " If a 2RPM motor rotating at 2 was within your claim of a 6% specification error, then a 2RPM motor rotating at 2 was within your claim of a 6% specification error. 12 RPM is a good starting point. A 2RPM motor rotating at 3RPM is 50% specification error, however. I don t believe that the motors RPM were 50% off spec, implying that it is just the wrong gearbox for 2RPM motor. I'm going to wait to write a review until I know if this product will be made correctly. br>Christopher Purdue"br>br>"Christopher Purdue"br>br>"Christopher Purdue"br>br>"Christopher Purdue"br>br>"Christopher Purdue"br "Hello Chris, I apologize for the error in my previous statement. br> I've spoken with the engineer about this issue. Normally, our motor's no-load speed cannot exceed 3 rpm; please download and review our specifications; we also have no idea why the data you tested had 3 rpm; perhaps your test results are incorrect. By the way, unlike stepper and servo motors, this reduction motor cannot be very precise because it lacks encoders and drive plates to record precise control. Servomotors or stepper motors can help you achieve 100% accuracy. If you want to be more precise when using a deceleration motor, you can add an encoder or a governor to fine tune it. br>Sorry for the inconvenience; if you don't need this one, please return it to Amazon warehouse before using it. I hope this information is useful to you; if you have any questions, please contact me! br>With best wishes, Ritabr>Greartisan Customer Service Teambr>Attachments: 37RGa981i- 37RGa981i- 37RGa981i- 37RGa981i- 37RGa 12V- 2RPM. pdf". br>br>After receiving this response, I decided to contact Amazon and request an exchange. They sent me a replacement and told me I had until February to return the old one. So, I recorded the unboxing and put both motors to the test, which you can see in the video that comes with this review. I checked the power supply voltage, which was 12 volts DC. I wrapped a strip of tape around each motor's shaft and timed a single rotation for each. It took 20 seconds to build the first motor. It takes 99 seconds to complete one full rotation, implying that it rotates at a speed of 2. 85RPM. Clearly outside of their 6% claim of 6% of their claim of 6% of their claim It took 24 hours to install the new motor. It takes 59 seconds to complete one full revolution, implying that it rotates at a speed of 2. 44RPM. It's better, but there's still a 2 error margin.
The wide range of speeds offered in nearly identical form factors is one of the nice features of this line of gear motors. One of the nice features of this line of gear motors is the wide range of speeds offered in nearly identical form factors. I'm not expecting a 10,000-hour lifespan, and I appreciate the small size and low price; the only thing I can think of to improve the basic design is to choose a motor with slightly larger solder lugs.
