Best Place to Start for a 6DOF Prioject

[vicpopo]

Hi,

You can have a look here : http://www.x-sim.de/forum/viewtopic.php?f=37&t=293

It's only a 2 dof with ac motors but you can find some answers and exemples for solutions.

I just keep going deeper and deeper with these motors, and i get more and more lost.
I found these motors,

can i take the controller off these or add them somehow? they seem to have the inverters attached to run straight from 240v power socket (australian standard wall plug)

EM1-14 1HP 1440rpm ø5/8" 240V 10A Yes Fan Cooled Plug & Lead

or i also found
MONARCH 3PH Foot mounted Electric Motor IP55

MONARCH Alloy - Three Phase Induction Motors are a range of high quality, Totally Enclosed Fan Cooled (TEFC), Squirrel Cage Induction motors, designed, manufactured and tested to the latest International and Australian Standards.

Model No. 191/0.75D4MAL
Motor Power KW 0.75
RPM 50Hz 1447
Supply Voltage V 380->415v Star 220->240v Delta

The other question i have, would it be possible to make a 3dof base, with 3 motors, with the intention to later expand?

I could not find details for the first motor you mentioned.

I think the second motor you mention is this one on this link:

This motor will do fine if you add to it a gearbox with ratio 90:1 or 100:1

You can do a 3DOF first but there are some things to consider:
-You will need larger power motors for 3DOF than for a 6DOF where the motors are working in pairs.
-You will need extra center support for alignment and center spring as well.
