Hi thecure :
Surely you have many disconnected track ... I suggest to put tin on all these weak tracks to see where the cuts are ? ...
Next time please ... upload pictures into this site as the other site is reported to my firewall as harmful and blocked ... I didn't see the details of your DIY board ...!!!

regards

So I connected the cables (see photo) .. right? .... Before connecting the motor, I connected the tester, but does not seem to (see video)

Then I connected the motor but does this ... see the video P.S: but in theory it should turn on an LED for each direction?

Hi thecure :
Good job ... please give me a pictures of the top board with MOSFET's .

- about the direction led ... I guess one of them is reverse installed ...
- about the noisy operation try to replace the feedback pot ... it seems that it has a defective aria ... makes the motor stops and doesn't have a direction to go to .

my board is 9.5x10 cm ... for one 50A DC motor ... higher rating is bigger ... but I've got your point ;) .

The HIP4081AIPZ driver chip is a peace of art for technology lovers and a peace of luxury not every one can have it ...

forgive those people like me how can't have a double layer boards or a nearby board etching service .
I'm simply can't buy anything from eBay .It will cost me more than making it like a dinosaur .
There are some people that are beyond last week :lol: "Discovery channel ".


I feel the same here in Turkey, we are almost on the same bot, :evil: thank you for your great efforts

speedy, seems great work,

I will study your post (at least 3 more) to consider to make my selves, I am absolutely a beginner and like to do DIY bases, can I count on your help?? :?:

Hi Vicpopo

As Speedy doesnt seem to be about

Is your H bridge still working and would you recommend the build, looking for a high current board to run 24v 650watt motors with an Arduino

Hi Telfel,

It doesn't work but that comes not from the conception , I burned it with bigworm motor (12 V , 190 Watt) and amc1.6.In fact these motors has got a very low impedance, I measured 0,7 Ohm.
The first positioning at starting ( starting xsim) the amc ask full power. That means the h-bridge starts on the short circuit.
I burned several h-bridges and this one also.

But Speedy said and I agree with , that this h-bridge can handle very powerfull motors.I didn't test it with 24 volts.

The h-bridge is not easy to solder .Before taking your decison look at Pololu drivers also.You can contact Prilad he could maybe try to contact Speedy for you.

Best Regards
