Which N20 gear motor is best for an RC excvator
HTML-код
- Опубликовано: 29 окт 2014
- In this video I take a look at a number of the fantastic N20 gear motors. Each motor has a different gear ratio, they are 1:50, 1:100, 1:150 and 1:200. I use the screw mechanism on the Liebherr 900 model to compare the different motors to see which best suits a radio controlled excavator.
The N20 motors were purchased on ebay: rctractorguy.co...

Where did you buy that linear actuator (the rod connected to the motor)
so what rate is more better? 1:50 as i understand?
Hi, Guy.
Please give me all the characteristics of the latest engine and gearbox.
Characteristics:
?-- rpm ( idling )
Gear Ratio ?: 1
? rpm @ ?V
Maybe you have a motor marking.
Thank you so much
Are this 6V or 12V motors?
can i use PWM to slow a 200 or 300 rpm motor?
yes
Are limit switches needed to stop the screws from damaging themselves?
Cheers.
What is the name of the hydraulic dynamo for the huina 1550 excavator to be strong
How would i connect one of these motors to a receiver? Is it just a case of fitting a connector plug on the end of the wires and plug it into a receiver channel?
what type of screw that you used it?can you tell me please
+Alif Haiqal For this it was a mild steel nail which I tapped to M3 and then soldered copper wire on the other end to attach it to the bucket.
Do you do anything with crawlers
Nice review , all these motors work at 12 v?
Whats about small servos? I watch many builds with servos in the arms of small size build excavators like the Volvo ec 460 in 1:32.the speed was smooth and range was nice but i dont know how are the lifting power?
+crawlervideo Yes servos work on these plastic models like this liebherr and the ec 460. Don't forget that a servo will always be carrying the weight of the boom where as the screw designs aren't loosing power holding up the boom so the batteries should last a lot longer but other than that I don't see any problem with servos.
How much rpm motor you were used
Muito bom,como você fez para rodar mais rapido? É a rotação por minuto,muito bom gostei,to fazendo a minha,breve lhe mostro,abraço!
Hi, I bought 4 different gearbox ratios 1:50, 1:100, 1:150 and 1:200 that gives me the initial difference in speed but at the end I used a 7.4 volt battery instead of a 3.7 volt battery which gave me a bit more speed. Good luck with your build, looking forward to seeing your work.
How weight it up?
How many weight it carry
from where you got that actuator attachment may i please have the link well done though
+Ibrahim Khan I made the actuators for this model. I used an N20 motor, some brass standoff for one side and a mild steel nail which I threaded to M3 for the other side.
where can i get the motor driver for this motor?
gostei muito. sabe me informa onde encontro esse motores com essa caixa de reducao.????
+Joserodolfo Schneider I usually get them on ebay, there are links here to the different types of N20 motors I buy rctractorguy.com/store/electronics
Obrigado.

Hi, I've watched a few of your videos and have seen the screw mechanism that is used on the arm however haven't been able to locate a seller given that I don't know what it's called. If you could let me know that would be great!
Linus Opat Well a linear actuator is what it is called but I haven't found commercially available ones small enough for this application yet. That is why I made my own using threaded bar and a brass stand off for this video.
Linus Opat Also a lot of people use a masonary drill bit instead of the threaded bar because it is faster.
Small doubt with the specified RPMs, is it for no load condition or max. efficiency condition?
Thanks for posting,did you find the gears where okay on the ebay motors?
+Rob Crawford Yes I haven't had any break yet so they must be okay.
Okay think i'll order some then,i got a few a while ago and the gears never meshed properly and when i fixed them to the drive the gears just slipped,yours look good though,i'll take a chance on them, thanks!
+Rob Crawford They sound terrible, definitely haven't experienced anything like that. I always buy from the sellers I've linked on this page rctractorguy.com/store/electronics
Okay i'll give those guys a shot.
@@RCTractorGuy hi mate whats the force of the motor I want n20 push rod actuators but was told they only had a push force of 1kg can u recommend a stronger motor but that the same size
👏👏👏👍
1200rpm
Okey yo ice una excavadora con estos motores pololu
