6dof motion simulator

Hi macrokefag,

Yes inverter with Vector Flow Control feature .I'm had some trouble to understand what you want to know!?

I found a nice interactive presentation of how the inverters drive the AC motors, with explanation of the various modes. Its for BLDC motor that are essentially the same as AC drive.

Hello Thanos,

Nice presentation!
Thank you.

Hi ,

A little point from my project .I finished the motors uper plateform.They all are in place and the designe looks great for me (hope the motion too ).
The distance between 2 motors where you see the ruler is about 58cm.My arms will measure 30cm between up and down platforms and 2 positions for the arms attached to the gearbox output shaft with 8cm and 11cm.

Platform

All the cables to connect motors to electrical box are ready , just the cables for the sensors are to solder.

And soon the first test unloaded.

This looks really awesome, and is quite a compact design, I really like it!
Can't wait to see it in motion.

Hi ,

The first test with the 6 motors and it works , yes

I'm happy because i was waiting for this moment for many months , about one year !

well done. nice seeing it moving. you are almost done. cant wait for the moment to see it with you on it

Hi ,
Thanks for support !

A new video with the sensor position and direction well setup.

For information to setup correctly this , see the link below and go to bottom page .

http://motionsim.blogspot.com/p/projects.html

And this is the video , the motors are in full speed 2400 rpm and with the gear ratio 105 that means 23rpm gear output shaft.

Hi,

As my uper platform is not yet finished , I builded a provisory wood plateform.I was wanting to test the 6 movements .I seated on it to measure how the motors will get hot and they don't !!
Sure I did not seat on the simulator many hours !

The motors speed is 50% their max speed setup (2400 rpm)

Thanks for the Update Gilles,

It seems that the dimensions are not set correctly in the 6DOF plugin, as I see the surge-sway motion is not flat...
Most likely, you need to increase the arm length dimension and play a little bit with the Top-Base ratio.

If you can't get it right, we should arrange a skype/teamviewer meeting so I calibrate it remotely for you.


Thanks
Thanos
