Paul & Sabrina's cheap DIY 144v motor controller

[MPaulHolmes]

Hi Damien! I'm sorry, I've been lost in "slave away, workin' for the man every night and day" mode. I don't have any schematic/PCB files for the 144v 500amp controller. Chris in New York had done the control board using protel (an old version of altium). I used to have the files on a computer in like 2009, but that computer went the way of the do-do bird.

Shmuel, yes like things -to-do said, you could use that high power IGBT controller to power 3 separate motors (all in torque mode) with a software modification. I'm actually getting some of the high powered DC control/driver boards fabricated, and they will be on the website in the next few days. You can email me about getting the software at pandspowerelectronics@gmail.com.

hi Paul, thanks, is the software for the IGBT controller ? because i think thingstodo send me that.

i want over the schematics for the 144v it will be pretty easy to change just wished i had the sch and pcb files.
on the other hand the sch and pcb files for the IGBT will not open on EAGLE or in PADSViewer, it give an error.

why did you guys never saved your work on the cloud? this way you will not lose anything.
I will open my DRIVE folder that contain what i got till now,(if that ok by you paul? and by you thingstodo?) its not a lot but then no need to send the files in mail, and it will not be lost.
the link will be in my signature.

I save my work on the cloud NOW! haha. At the time (2009) I was in washington, where it rained a lot, so I just figured that even if I put sensitive electronics in the cloud, it would just get all wet and be ruined.

lol i see your point, so no need to open my drive ?

I have those old files for 500A controller in my Google Drive. Don't see any .pcb or .sch though.

so you just used the PDF file to make the controller circuit PCB ?

I didn't make PCBs myself, I've always ordered them from Paul. Will gladly support him for the work he has done.

i see, thanks, i would have bought it, but i need to change it for 3 pwm signals so it won't work for me.

i will make the pcb just wished i had the start.

Actually, if you want to control 3 motors independently, you could just use the AC control/driver board with a software change that would be pretty easy.

the IGBT right ? its way to large for me, im going to run 1 48V 250amp, and 2 smaller.

i changed the items so it will be cheaper for my build:

1) MOSFET Transistor, N Channel, 295 A, 60 V, 0.00165 ohm, 10 V, 3.7 V
2) Electrolytic Capacitor, 1200 µF, 63 V, HPR Series, 2000 hours @ 105°C, ± 20%
3) DC Film Capacitor, 2.2 µF, 450 V, PP (Polypropylene), ± 5%, ECWFE Series
4) Standard Recovery Diode, 650 V, 150 A, Dual Common Anode, 1.7 V, 108 ns, 580 A
5) LEM Current Transducer, HO-P Series, PCB, 100A, -250A to 250A, 1 %, Voltage Output, 5 Vdc

but im not sure with 2 items.
1) the Capacitor, is for the ripple effect (right? to try manage the voltage spike?) does 1 of each is enough ?
2) does the Recovery Diode need to get the full amp size ? do i need to get 1 or 2 of this ?
if all this is good it will cost me 30$ only(for the power circuit).
