I burned up several motors with it, so it seems it wasn’t the weakest link up to about A for brief durations.
IRFS 3107-7 reel
It would be a orfs3107 small present compared to all the cool info you share! 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: Okay, so I know I said that one of the best things about building a brushed DC motor-based snow scooter was that for just this once Irfs1307 do not have to design a motor controller for the project 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 idfs3107 code tidbits from your code.
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 irfs307, a less critical point. As long as phase current and rotor position are sampled synchronously, the speed of the slow loop can be reduced to fit the processor.
Would you mind posting some more information about it such as bill of material, eagle files and arduino sketches. Newer Post Older Post Home. Thanks and again great job.

I mean the high side, is it should be a P-Channel mosfet? Shane Colton August 25, at Posted by Shane Colton at Patrick M January 21, at 6: Oh, and it runs on an Arduino. Thesis ] [ S. Shane Colton January 24, at 5: Shane Colton April 22, at 1: Did I forget to mention that? Hi Shane, I thought that you might not be able to restrain yourself from designing another controller for this project! I love those multi-source pin FETs too, but achieving good cooling is a bit harder with them than with regular FETs, which is why I don’t use them.
I’m a student from Brazil, willing to build a DC-motor controller as you have done but for a different application: Maybe it also makes me more careless about power-side layout, though Kevin April 18, at 3: Before I forget, I want to thank you for posting your brushless controller’s source code a month or so ago – very cool and also very generous of you, Shane!
Hi Shane, I got some question on this circuit.
Shane Colton July 9, at I appreciate your help and congrats for the blog! Hopefully, it will just work and I can plop two of them into the snow scooter to run at 18V-ish.
BTW, I think you could have pulled off making this controller without any isolation and maybe also faster switching speeds thus less switching losses and less parts count.
Because these are such massive FETs, they take a good microsecond to turn on and off with ohm gate resistors. I’ve only tested on the bench supply, but it was able to drive about 25A before alligator clips started melting. 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 Well, I made my PCB, with all the gate resistors, reverse diodes coupled with the Mosfets, pull-down resistors attached to gate-source pins, but I’m facing a heating problem in the HIP: The motors might not last that long, though.
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? Hope you were able to get it working, though!
