As I understand I need to reduce the in my case 1500 rpm back to +/- 30rpm.. I am thinking of 6 0,75 KW motors but then I need the reduction, then I have all kind op options and I am not sure what to pick. mainly it has to do with the CM value, CM30,CM50,CM75?!?!
What would I need as I am not sure what it means. al I know is the higher the number the pricier :-) And I want to keep the cost as low as possible!!
3 phase 4 pole ac motor 1380-1500 rpm with 60:1 wormgear box should work fine. higher the gear ratio, more torque.
75 is the size of gear box, an 075 with 0.75kw motor should be correct, just make sure the flange matches eg. B5 flange. above 0.75kw you will need an 090 gearbox, which is what i went with for 1.1kw motor. oh and make you ask for a double shaft on the gear box to help mounting the pot.
if you wanna save money might be better to get from china. I saved about £700 (door to door) vs buying domestic.
once you move above 0.75kw.. bigger motor, bigger gearbox, bigger VFD so costs do start to increase quite a bit.
Budgetwise not really the answer I really wanted :-) I'd rather would have like to hear that a CM30 would fit a 0,75Kw motor :-(
But thanks for clearing this for me..
This causes me to call on all European members, anyone having a good source for motors with reduction for reasonable prises in Europe? Otherwise I would need to source something in China, but the shipping makes it expensive again..
there is of course the china branded inverters which is cheaper than european or japanese designed inverters. Some is quite good, what u need to look for is 1) Vector control 2) PNP and NPN switch for digital input terminal 3) autotune (usually any vector control will have) and inertia or Kp/Ki tuning (very rare in chinese inverters)

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
