Hey all,
Been a hot heavy min since I've been on here.
2020 has been a complete nightmare for me. I lost my daughter River to a heart defect at 2.5mo old. She was a real fighter having had open heart surgery at day 5. She was born with TGA a disease where AORTA and PULMONARY arteries are switched..Aint that some shit? Congenital heart disease is a lot more common than you think 1/100 new born kids have a defect of some sort. Needless to say the whole ordeal has been a nightmare for my wife and I.
I've been working from home with the whole covid thing and have been doing a bit of biking with the wife so I had my ebike back out. Did a bit of research on speed controllers since I had left off and BOY! was I surprised...
I discovered VESC (I know..welcome to earth Mo)
I did a bit more research and found some decent designs. One in particular by Gelp on the Vesc group. He calls his vesc BESC which can do 150V at 200AMPS. I also saw a design called cheap FOCer. Loved the name and more simple design vs ben's VESC.
Fast forward a week or two and you have my new PCB and design . Done after BESC, VESC, FOCer and Axiom. A modular, cheap, small, low part count, high power, controller.
It will be a two part controller with power stage and control separate. I am done the control section send the boards out. The idea is to have a control section I can stick down onto any level power board. This is like the axiom just with way less parts. More simple if you will. Doing the power section now. Will add details as I go. I will be using ASC series hall sensors to measure current like the besc. But I'll use different drivers and fets.
Here is a sneak peak. Grandpa did it in Eagle..
