Which motors work flawless with an fbl-2360 at low speed?

4 years 6 days ago - 4 years 6 days ago #29532342 by Erik
Can anybody recommend bldc motors who sure (tested) will work perfect with my fbl-2360 in closed loop mode?

They have to be waterresistant for outdoor use and be able to work very precise in a lawnmowing robot to mow along walls. Max. 10-20 Amp per channel.

Oh and i also like it a lot if they are as silent as possible (like hubmotors). Tachometre, encoders, hallsensors i don't mind as long as they are precise and easy work with the roboteq.

I've worked with parker bayside DX series servo wheels. You have everything integrated, servo (obviously), gearhead (you can choose the ratio you want), tire, breaks (optional), you can choose between 3 different servo power, and they have hall sensors as feedback.

I have worked in speed closed loop with FBL2360 and there are no problems.

But servos are extremely difficult to disassemble therefore they are difficult to maintain.

I hope it helps you.

Victor

Thanks very much Victor!

Yes this is what i'm looking for...they come in 8" which is a bit small to drive over uneven floors but i can fix the floors as well..And they will make the robot a lot higher, i allready made my mower and brushes on actuators who will be too short if i raise the height.

But i can change those things as well, the motors look like the quality i'm after and i also found them on ebay. With these i can use my hubmotors as frontwheels and just cut the magnets out.

I was also thinking about segway motors, they have the same gearing but are not brushless.

Well you have given me new hope, i won't waste my time anymore on the 15 pole hubmotors i have now...wether they exist or not with 15 poles. These look like professional machinemotors and all my parts are high quality except the wheels i got now.

I'm going to do my homework and try to find video's about them. Thanks a lot!

Dear Erik,

I'm glad to hear that.

If you are really interested in buying bayside servos. I can give you the mail of a person who works on a big company in USA and they are selling a few of these servos. I have bought my servo wheels from him. They are selling them really cheap and all the servos are new.

Please let me know if you want me to send you the email address.

Regards,
Victor.

Hi Victor,

I use this emailaddress for forums, This email address is being protected from spambots. You need JavaScript enabled to view it.

They don't make much noise do they? I choosed the hubmotors because they are ultrasilent and don't use much space. Gears always make some noise though but also produce more torque and that's what i need. Some noise is fine with me as long as they don't sound like cheap rc-car motors.

Please send me the emailadres of your friend, i'm very interested in them. I searched for similar motors in Japan and Germany but can't find it yet, also they are not tested with the roboteq which is a huge plus for me.

Thanks a lot!

Dear Erik,

Dx servo wheels are really difficult to find and really expensive but the guy who is selling them doesn't need the servos anymore because the project he was supposed to use the servos never became a reallity.

Servos are really quiet, I have the 1 hp model with 34:1 gearhead and an output torque of aprox. 100 Nm.

I'm using them in mixed mode 2 with speed closed loop. They are 8 pole 24 volts servos.

I will send you the email address to your mail.

If you something else, let me know.

Regards,
Victor.

Thanks Victor, i received your mail.

Did you see the link i sent you? Are they the same motors?

I don't know why but suddenly my open loop mode (loaded the config from harddisk) has way more power, extreme much, the robot makes wheely's all the time even in 10 amp. mode...Also the motors sound more agressive now and make more noise.

I have to figure out why that is, i can't drive it slow without adjusting the throttle curve at the rc-remote.

Hopefully Blake can tell me how to run it in closed loop mode or i need the new wheels.

I have a Kincect 2.0 camera waiting to be installed on it, not sure what that thing exactly can do but i want it to control a watercanon which i allready have here. It has to aim the canon at straydogs and cats and even chase/attack them since they have rabies and i hate them, have been bitten allready by one.

So i need waterproof ultrasoon sensors or waterproof infrared sensors from industrial quality. (not the arduino sensors, have them allready to test). I also like to have another camera and a gimbal...or only the gimbal (waterproof)...also a good gimbal for the watercanon, i need a Udoo x86 but you don't have them, a waterproof 20-30 Amp. emergency switch with big red button on top, a gps-tracker, the sensor for follow-me mode, sensor for detecting rain and one for light (all industrial waterproof quality)..

Maybe a (cheapo) laser-range finder if the Kinect2 can't scan properly, have to test it first. But for the rest i have it all and love the shop banggood.com. Also in chinatown (Bangkok) they have loads of used industrial parts, have to check it out there first as well.

Thanks for the help so far and if you have something for sale let me know what..
