Re: prodigy evo

The spin-up test went rather well; the biggest issue so far as I can tell is that even on soft start the motor spins up too fast making the belts slip so torque is not a real problem.

Temperatures are fine, everything stays pretty much cold to lukewarm. After a 2 minute spin no part of the system went beyond 55 degrees C, and that part that did get that warm was the center axle on top of the motor, not the motor itself (so there is a bit of friction there). The only downside I see to this configuration at the moment is that it takes a long time to spin down. Nothing a drive into the wall won't fix.

Video?

No video as of yet.

Re: prodigy evo

You should always video spin tests in case something goes horribly wrong! Then at least you'll get a cool video out of it.....

Re: prodigy evo

Or to show off how vicious your new machine/setup is! I really want Sam to upload the video of NST on its brushless setup... it sounds like a tornado screeching!

Re: prodigy evo

That's sounds pretty good then Leo! Having spoke to glen about those belts he did say the green ones were quite hard, but having a bit of slip is a good thing.

Be good to see a brushless spinner that works reliably on budget components.

What sort of current draw does it pull?

Re: prodigy evo

Sounds good, looking forward to the end result, spin down time isn't a issue :-)

Starting to take shape
15mm sidewall, 10mm top and bottom armor, a tad over 2 kg, of the 4 we had left , HDPE welded and reinforced , with some shape outside cube.

any remaining weight will go on more armour, maybe removable? when fighting these pesky spinners!

Re: prodigy evo

The joints on the HDPE ain't milled right trough.
But bending 15mm HDPE accuratly is not easy, not even with industrial heatguns.
So, the hybrid solution. The joints are milled out 8mm deep, leaving 6mm thick HDPE solid. The rest will be welded and the ali supports replaced by Hardox angles.

Re: prodigy evo

Sounds nice and tough

Re: prodigy evo

Bit more armour done
