Many tires have a quite flat profile and good threads so it might work, and then I could use much smaller diameter, smoother tires as the drive wheels.
I’ve used the IRS drivers for my brushless controllers without isolation and they seem to work well up to 50A, but idfs3107 some reason it just makes me more comfortable having an optical barrier in the circuit. I haven’t looked at it for a couple weeks now, but I think it’s the version that runs on the 32 bit MCU, right? I’ve only tested on the bench supply, but it was able to drive about 25A before alligator clips started melting.

I burned up several motors with it, so it seems it wasn’t the weakest link up to about A for brief durations. Thanks and again great job. Monday, January 10, Victor Did I forget to mention that? Once I get it hooked up properly to a battery, I’ll be able to really load test it. Shane Colton July 7, at I hope you’ve been able to figure out the issue and get your gate driver working!
Hi Shane, I thought that you might not be able to restrain yourself from designing another controller for irfs31077 project! Aside from the fact that I soldered four out of six diodes in backwards the first time, the controller so far seems to work. Hi is it possible to post the design orfs3107 to a working link?
MA March 26, at 2: If I do try this out and it works I’ll send you a photo I’ll probably post it on the endless sphere ebike forum – http: Posted by Shane Colton at If the brushes get vaporized, I’ll probably switch to sensored brushless, for which I already have a pretty good solution. The previous design was based on a bit MSPF Click for full resolution image. However, the code is virtually the same in terms of structure.
I’m kind of new at this thing.
I chose a capacitor C10 above to set the dead-time to 1. Caio May 31, at 5: Patrick M January 21, at 6: Oh, and it runs on an Arduino. Kevin Urfs3107 22, at 6: One important thing that would reduce ground noise much in your layout would be to tie the low side FET sources together very closely instead of doing this to the high side FET drains, a less critical point.
But, as I found out in urfs3107 of my many other controller troubleshooting sessionsslowing down the gate drive a little can sometimes help clean up noise. Shane Colton January 24, at 5: I borrowed it for the photo. Hi Caio, Thanks for the kind words.
Well, I made my PCB, with all the gate resistors, irfs307 diodes coupled with the Mosfets, pull-down resistors attached to gate-source pins, but I’m facing a irfs3170 problem in the HIP: I ask because I have my own controller designed around a 8 bit PIC 18Fand was thinking of having some fun with some of the tastier code tidbits from your code.
For now, here’s the full schematic:. Hi Shane, I got some question on this circuit.
Because these are such massive FETs, they take a good microsecond to turn on and off with ohm gate resistors. This one’s not mine, okay? Also, additionnal power capacitor bypassing for high frequencies would be crucial when trying to switch your FETs faster – cheap MLCC’s are really great for this. Hopefully, it will just work irs3107 I can plop two of them into the snow scooter to run at 18V-ish.

Shane Colton April irs3107, at 1: It would be a very small present compared to all the cool info you share! I’ve just entered this universe, even studying electrical engineering, and I’ve started my own board with a gate driver, the HIP, that’s the only thing I had available What’s that blue thing?
Great write up and controller Shane. If anything, I would have expected the FETs to take the heat in that case. The motors might not last that long, though. What I was thinking of doing sometime is modify my firmware to make a dual brushed motor control mode – that would make for a very versatile controller.
