Yep, I mirror what guys below said. Very good breakdown. I have seen inside the gears before so knew what I would look like inside. But being told the pro/cons and the information about the materials of the different stages of a planetary (eg, nylon vs metal) was great info. And best of all, being told exact meaning of spur.. It got me thinking that a planetary must be spur also, and then having it confirmed a few minutes later was great. Clears up some confusion I always seem to have when looking at motors on websites
Glad to see people like you making proper use of TH-cam. Thanks for the informative breakdown and one suggestion; give the other guy a chance to speak ;)
Nice explanation. Keep the videos coming!
Thank you! Will do!
Very informative. Thank you!
Great Video! Thanks for the informative break down.
Thanks! Glad you found it helpful!
Nice explanation. thanks a lot
Glad you found the video helpful!
Where can I get a brushless outrunnner motor about 1000kv to 1500kv with planetary 4:1 to 6:1 gearbox?
Hello guys, thanks for the great video! I have a question, hoping you could answer it. I am currently looking at the following three products on your website:
1. 5201 Series, 26:1 Ratio, 210 RPM Spur Gear Motor w/Encoder
2. 4" Heavy Duty Wheel
3. Clamping D-Hubs (Tapped), 0.770" Pattern
I was wondering: is it enough to use the clamping D-hubs to attach the shaft of the gear motor to the wheel? Do the hubs and the wheel have the same kind of hole patterns to be used with the same type of screws? Thank you!
Yes! If you could attach part numbers I can check the exact part fitment. But that should all work!
Can a typical brushless 3650 motor fit in the planetary gearbox? What size pinion?
Great video! I'm curious what would occur if the wax-like lubricant were replaced with gear lube grease (like the ones pressed into zerk fittings in larger machine applications) and if this would lend to even longer life. I've replaced the OEM lubricant in my impact gun with synthetic lube grease after the OEM stuff broke down and caused it to seize. A year later, my impact gun is going strong.
One can reasonably assume for generic parts whatever is used is primarily chosen for cost purposes.
Find out what high-end motors use, and do likewise. I wouldn't just use a different grease made for metal for a nylon application.
Do I need a gearbox with this if I'm gonna use it on a rc 110scale crawler chassis
Can u support by explaining how to reduce cyclic noise in this planatory gear box
Nice bro
Any chance you can demonstrate stalling a gear motor? Would be great to see more videos...
Thank you for your feedback. We will hopefully have some new videos rolling out this next year. We wills send your feeeback to our technical team.
Please explain me shaft length ?
what is the opposite of a reducer? is there a motor with planetary gears inside them to power a larger radius and add rotations to the smaller radius center axis? like a brushless motor with the magnetic ring rotor and inside there a planetary gear speeding up the rotations?
That's something that isn't commonly available, generally it is easier and cheaper to wind a motor to spin faster than it is to add an external geared "overdrive" setup.
@@ServoCity ok thanks
What is that software? used for showing cross-section of gearbox?
We use a variety of software programs. A few of our favorites include Keyshot, Blender.
Which have more torque
Which one among these two is better for backdrivability?
A planetary gearbox is more robust and will better withstand being backdriven. The ratio you backdrive has a lot to do with it; if that ratio is too great, it will be very difficult to backdrive and cause a lot of stress on the gears. Feel free to email us should you have any other questions tech@servocity.com.
Which type would haver the least amount of free rotary motion, ie rotary wobble when no power exists.
Backlash is not something that is directly related to the gearbox style (at least when comparing spur vs planetary). Both have the potential for a bit of backlash as there's typically a tiny bit of tolerance built-in between each mating gear. Feel free to contact our Tech Team should you have any additional questions tech@servocity.com
Hey, I think the title of this video should be "Compound gear train motor Vs Planetary gear train motor" because both motors have spur gears only..
An astute observation. I would be lying if I said we had not had a conversation along these lines before shooting this video. We opted for the more common nomenclature.
sir I am going to make a ebike which motor should I USE 775 spur gear motor or 775 planetary gear motor
????????????????????????/???/??? pls reply
We appreciate thinking of us! We aren't experts in ebikes and such I don't believe we're the best people to answer that question well.
At face value we would go with a Planetary gear motor in most heavy-duty applications similar to ebikes. But we recommend looking for other members of the community who may be more well-versed in the intricacies of ebikes.
👍👍👍👌💐
Spur gears have low noise? Other pointers on net denote "spur gears make most noise"
helical better helical + planetary even better
i need a gearbox to inrease speed
