And as for the motors not staying in position after you turn them off, same problem here. I think its the way they are designed, thats all.
They look good, toss a car battery on it for testing and have some fun!

The power supplies are reated 30A but even running the JRK's at 27,5A already killed one of them. That's what you get with chinese electronics, specs always seem to be off ;)
For now I want to stick within the JRK's max 30A but who knows I might push them further once I've tested it all.

Let me know how you get on with the power supplies - I need four !

MCP list the current as 23A but I have seen the spec. sheet from the original Chinese source that lists the current as 27A. The only thing I haven't found out yet is if this is the Stall Current. If it isn't then the Stall current is going to be quite a bit higher. As Zach (MCP) didn't know I emailed the Chinese source, it was sent two weeks ago but no response yet.

What length of lever arm are you using ?

Of course I'll share my findings with the new psu's, II reckon it will take about 2 weeks for them to get here.
I'm not going to risk killing the 2nd 30A supply as well since I want to try and sell it (hope I can fix the other one as well).

Current of the motors is listed as 23A indeed, but stall current will be a lot higher. I tested them starting at 20A but at that rate they had problems lifting the platform, they started doing their job like they should from 25A and up (baring in mind that my platform is a bit front heavy if noone is on it! So they will have less problems once a driver is on it since the platform will be better balanced then).

The arms are 8cm in length and the distance between the centers of the 2 holes is 55mm

23 amps sounds a bit high for rated. I'd hate to think they are 46 amps stall.
My big worm gears are 16 amps rated and about 30-34 amps stall.

I did say these motors suck some power to get them to move.... ;)

Oh and put the second 30 amp power supply on a car battery in parallel if you just want to test the motors while you wait for the big PSU's.

Shot some quick photo's of the rebuild sim today. Will do a decent photoshoot when it's all finished (with a proper flash set).

As you can see I added some skateboard griptape to prevent skidding and damage to the paint. And also added a few aluminum strips where the feet of the pedal base slide over whilst adjusting it.

Still waiting for my new PSU's so didn't get to using it yet :roll:

Great job there, very professional.
Sir should be happy with those pics.
Now for you to get the big motors running.....time to sort PID, motion, blah, blah.

Thanks for the compliments!

Now let's hope the psu's arrive soon so I can get it up and running ;)

---> What a beauty! I like the quality of your build very much. If you want to go more crazy - what about powder coating some parts or use all screws anodised in red :lol:

how did you cut the piece of wood, and how did you bevel angles?
finish resembles a machine? router?
painting seems to be a plastic coating what is it?
