I'm wrapping up testing on the BLDC (brushless DC) controller and motor. Just a (hopefully) quick review. motor is 28 pole (14 n-s magnet pairs). 550 in/Lb torque, 24vdc,200rpm,about 550 Watts. Got a whole pallet of these for $20/ea. Sold a couple to a University wind department for turbine blade development and recouped my investment. So there are 6 left. didn't have the heart to throw them out, sell, or scrap them for 12 years, so it must be fate! It turns out they only had 2 hall sensors in them for SIN/COS (trig stuff), so made a hall PCB with 3 @ 120 degrees. The motors had a very cool fiber ring with n-s magnets matching the rotor magnets. A CAD drawing (and 2 hours later) came up with spacing for the halls. put the board in and it worked the first time! Bout had a heart attack! The BLDC drive from china I tore apart to see what was in there upon arrival and found it to be of high quality with good (79 amp)IR MOSFETS and a serious controller chip all for $55. Had a little trouble with the 0-5v input hitting top speed at 2v, but again tore it apart and located the scaling pot and boom! worked perfect. Sorry for the lengthy post.
I have a question, which cable(awg) you use to connect the 6 vfd the power outlet?
Usually its 16 AWG for the motor wires and 14 AWG for single phase input of the VFD inverter. But you can use thicker wires if you like, just in case you will be drawing more amps than usual during rapid accelerations and decelerations of the motors.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

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.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

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
