Hey Scott, I think I found an error in your code and a reason why the motor wouldn't spin very fast. In your switch cases I think you have your ports D and B backwards for case 3, 4, and 5. If you look at the direction (DDRD) registers in setup) you are manipulating registers that you haven't declared as output, which also happens to be exactly flipped between D and B. I think the only thing you'll need to do is flip them back.
Another reason the wheel won't spin quickly is because you only had it hooked to 15 volts. From the looks of it you'll need at least 36.

I thought about making my own pedilac and powering it mainly with solar panels. Just think about it: when your battery runs dry you just chillex on a green lawn, unfold your solar panel, eat, drink, chill and then after an hour you have power again.
or even mount the solarpanel in a way that it charges the bike all the time. at least the math somehow adds up: a foldable 80W panel should be small enough, but provide enough power even on cloudy days.

This is actually pretty good. You should have turned this into a PCB, and then either etch a PCB at home or order from JLC PCB. Also about the ESC, is a micro controller really mandatory, or is there a way around it, because I am terrible at anything that involves code, and I think it can be done. Also, I recommend SMD components for the final board. Good job.

BTW, it's not codes, it's just code. When referring to programming, the code refers to all the program instructions. Each line of code is just call that, a line of code, not a code. A code is what you'd use to encrypt your messages so the enemy cant read them.

Great video and clarity in explanation. it is good for rotating the wheel with no load but if will burn out if u use it for the eBike. i would be great to see a real 48v version of this. i have been trying my own but current level is too high.

The whisper. And I love your Videos. Great work Great Scott. I'm sure you get that way too much. I appreciate your thorough explanations and rebuilding the wheel approach to help yourself and others understand.

Hi, is there a way to hack a SENSORED ESC to make it a sensorlesss one, i meen to generate a signal and feed it to the ESC thinking like a hall sensor is attached to it, to simulate the desired pedal speed?

I'm not sure why you would go through all the trouble to create a controller that would allow you to power a 48V motor with 7 volts of power, but whatever, it is a very intriguing schematic though.

Nice work I watch your video a lot however my question is can this ESC works on a IGBT at 220v dc also is the 15 volt that drives the IC has to be isolated
Thank you
