Showroom ODESC (Odrive) - BLDC - Linear Actuator (WYBO 200 / WYBO CONTROLLER)

Hello everybody,

After having acquired a lot of experience during my first project, concerning the construction of a 6 dof simulator, I decided to relaunch myself in a new project.

The link to the thread of my first project for information : https://www.xsimulator.net/community/threads/6-dof-odrive-bldc-new-design.14580/

The purpose is now, to build a 4 dof simulator based on an aluminum Prosimu frame .

The originality will be the linear actuators.... I name them: WYBO 200

I want to develop a new actuator based on an open SFX but fully different into it….

Indeed, it will be a real pull/push actuator motorized by a custom Servo - brushless DC motor and high quality components...

To finish the best : I’m going to use an ODESC as a controller & driver to pilot the motor.
And AMT 102V for encoder

I will share more details during the evolution of the project.

This the ODESC 3.6 that i'm going to use. Compared to the odrive, there's many improvement like high quality capacitor or the add of an heat dissipation, etc.... . You can find the description at this link if you want to know more: https://sequremall.com/collections/odesc/products/odesc-dual-drive

This the BLDC motor that i'm going to use: 6354 140 KV
With 2450 W power and 7 N.m torque, it will be enough to move my aluminum frame ;-)

Looking forward to seeing this come together. How do you anticipate the final cost will compare to the SFX actuators?

Hi,

It's a good question that i wanted to answer since a long time. To answer your question, i make a table to compare only, the motor set between odrive solution and AMC solution... I don't want to discuss about this subject.... The conclusion is enough clear on the table i think.... Thanks

Thanks. I'm excited to see this project as it progresses. I'm building a DD wheel with an ODESC (have all the parts, just need the time to start working on it), and I was planning on a BLDC/ODESC motion rig next.

Can't wait to see what you come up with

Thanks !!! I have also the project to build a ffb wheel with ODESC ... when i will finished the ODESC BLDC actuator.... I will add some news the next week ;-) Do you have a thread of your work ?

Not yet, but once I get the actual build started, I'll be sure to post progress here.

You forgot to mention that the AASD servos are available from small sizes and power (flange 60mm 400watt) to huge power and flange size (flange 130mm 5KW)...

And don't forget the safeties included in these industrial servos, STALL protection, Over Torque protection, Overspeed protection, Automatic detection of faulty encoders or cabling, lower currents running through cabling compared to DC solutions... in short, everything to not worry if something catches fire!

Hi thanos,

As i said, on another thread, this table is an answer of peope who asked me the difference price between the two solution. So i make a comparison with the price criteria only.... As i said, the amc solution is easiest than odrive solution. I don't want to discuss about who is the best..... Both solutions deserve to exist ;-)
Another thing, you know that it's not adviced to build a rig with a 60ST ac motor because , torque is too low.....That's why , 100 % people use 90 ST or 80 ST motor....
In odrive firmware that i use, there's also several security about speed, current , torque etc.....

I repeat, there's no competition.....Both solutions deserve to exist....People make their choice ;-)

Sure. But another item not included in the cost math in that table, the high quality shielded wiring for the servomotor power and encoders that is included in the servo drive and servomotors kits.

In DIY BLDC, you could spend lots of money and time having to gather the really thick AWG wiring, manufacture your own cables, add shielding, and also build the shielded wiring for the encoder.

It's very easy for someone without experience in making such wiring, to make mistakes that can cause problems, happened to me even with experience in the matter. I try to use systems where you don't need to make any wiring or cables, and use what is available off the shelve, already build!

Again, pointing out what really matters, not competing, and that users should educate for themselves before take on something because its a few $ cheaper. Almost every time there's a catch.

i have the same odesc board but i cant configure the board because i have minimal experience about this board...

odrive based board not as easy as vesc based....
and its not intuitive at all because it doesnt have UI like vesc, but it still have very big potential if someone can build using odrive based board...

Hi,

VESC is used to control motor speed. With ODESC or Odrive, we use it in control position mode. There's several tutorial on youtube that show you, how to set it easily...

Odrive have official GUI and others non official GUI. I invite you to make some search on odrive forum community ;-)

Good work

Hello,

Work is progressing....

The actuator is fully designed ....
Stroke is : 200 mm (+ 20 mm security stroke)

The actuator uses a custom sevo brushless motor with integrated fan
The actuator can be used in real push/pull mode with u-joint on each side if needed.
If needed for fun , the actuator can work without motor cover ( but it's not secured to do that )

It's time to print the different parts in PETG ....

Hi,
There' s some news about the development of the actuator. I made some improvements as you can see on photos.... The fan is now a separate module that you can add in option. Power cable and encoder cable is now securised by a cover... To finish, i added a plate to secure the access of the coupling.
It gives a nice actuator

About the ODESC, i made a test bench to develop and set correctly the board.... The final will be a good surprise !!! It's for soon
And the real

The first real actuator looks very cool !!!

Thanks for the update. Excited to see how it performs for you.

Hey Will,
thanks for the great work on this project. Very very sexy.

Could you tell us your experience with this actuator in the past months and what, if anything, you would do differently a second time around?

Would you be so kind to post a little parts list? Which aluminum profile (100x100 or 80x80? Length?), which ball screw (width/length/lead), which hollow shaft?

Thank you so much.

Hi,
The actuator is working perfectly and have a strong conception. I have designed a second version with some improvement .... About the control, i'm working on a solution specifically for odrive. It will be a new post.

For now, i can't share the design but certainly in a near future on a website that i will share the link. Some details:
Aluminum profile : 80x80
ballscrew 1605 with a specifical nut
Hollow shaft: Outer diameter : 30 mm

I use mostly standard part that can be find on aliexpress as sfx...
Other dimensions are depending to your design....

Good work ;-)
