- In this video I talk about dc motors and recommended speed. At the end of video we calculate wheel diameter and speed of lawnmower.

Good explanation👍
Excellent video. It sure will inspire me to continue working on my lawnmower. Btw, on one of my projects I use the same motors, power full and cheap! I'm looking forward to see more of your videos.
Thank you!
Very useful video😀
the knowledge is very useful, thank you sir
Thanks, I try my best to give something to community
Thanks
waau you are clear & melody voice with presentation i also start full electric powered rc lan mover
Thanks, wish you all the best with your project 😀
Great video. Can you suggest a motor driver for MY1016ZL motor which is compatible for pixhawk.
I dont have experiance with pixhawk, but what I have seen from manual, every motor controller with rc sgnal or pwm signal input should do the job. Look for sabertooth or cytron motor controller
Little help.
I have 4 motors with this specs:
Supply voltage: 24V
Rated current 1.4A
Rotational speed: 1260 rpm
Gear: 145
Would all four be enough to start and have enough power to wriggle through the grass?
Hi, sorry I am not shure if I understand this right. Your rpm is 1260/145=8.7? For 25cm wheel you need 75rpm to go 3km/h. Your robot will be too slow. What are you trying to build?
4:46 je to tomo vinkovič srk 70 kosilnica ? trenutno tudi jaz predelujemo to kosilnico na električni pogon z dvemi 250 w motorji. bo to dovolj za pogon v strmine ?
Tole je Sachs and Vettel motor narejen v osemdesetih, dvotakten. Za kosilnico cca 100kg bodo 250w motorji ok tudi za v strmine.
Thanks as usual. Are you going to eventually move it into Ardupilot?
Hi, yes I am thinking about it for long time. It is hell of the project. I have to sort things out theoretically first, becouse I am a little bit confused when looking ardupilot hardware. I am not shure which hardware is compatible and cost effective. Did you make any progress?
Hi, do you have the reference for all terrain wheel ? Please
Sorry didnt understand your question. Could you explain a little bit, thanks
Rather than use arduino why not attach relays direct to your RC receiver?
Do you think you could have just used the wheelchair motors with better tyres instead of tracks?
I notice the newer Chinese Rc mowers are using much better brushless motors and differentials to power their tracks now
Hi, you can not attach relays to RC receiver directly. You need some sort of controller to handle the rc signal and control relays.
For higher slopes you must have 4WD or tracks. If you dont have high slopes you are fine with 2WD and better wheels.
Brushless motors are better because they have constant torque and no brushess, however motor contollers for brushelss motor are more expensive
@@gregorkobetic you can easily attach a relay to a receiver - what makes you think you can’t?
@@janramonmartin you can if you use relays for Rc receiver. What you can not do is connect standard relay that you can buy in every electronic shop. Thats all am I saying. Have a nice day!
*Where is it cheaper to use a hydraulic motor with a magnetic motor boss?*
I am not shure if I am qualified to answer this question, but long time ago I checked this possibilitie, and I remember that hydraulic motor were very expensive. Not shure how are prices in China now.
我的视频里也有割草机
Profi machine :)
Hi,
The tracked version is very cool but more expensive.
Here's my version for 4x4 with chains and two chain tensioners on each side.
It weighs about 120KG and works great:

Drive train in detail :

I did have a lot of problems in soft soil with the drive train because of the weight before the two chain tensioners on each side.
It looks realy nice. Very well made. Congrats on sucessfull project!
Now I know not to use chain 4x4 drive and why all Chinese manufacturers have stopped doing it.
True 😉. Made mower that you saw in this video with 2 motors and chain to be 4WD. Trying to do zero turn, didn't move for inch 🤣
