I am starting my own project, 1995 Ram 1500 alternator from junkyard.
Bought myself a brushed controller off of Amazon 36V 500W because it would be shipped to my place within 2 days, hopefully.
I was planning on using the brushed controller for the phases, and just powering field with 9-12V separate battery. I got everything ready to go, waiting on brushed controller.
Ideally I'd use a Greentime controller 48V 1000W, SENSORLESS of course. Then I can use regular ebike throttle.
This is my junky ebike, lock it up and be away from it for hours. Workout at the gym, go to the mall, library.
Will the alternator motor conversion have enough power to go 1.25 miles up a 1% grade with 375lbs?
Round trip of course, half is downhill, so say 3 miles total, I have plenty of battery.
edit - Of course I checked out Hobbyking, but their high voltage esc's are expensive. Not sure if the 1-6S esc's are even worth it for my application, but they do have high amps usually 60A-100A so thats what must make up the difference, plus they are so small. Everyone that does this alt-motor conv on yt, just rides around on flat ground for a minute.
Your alternator, if it had 6 posts before the diodes/rectifier, then yeah its just two ends of one phase, with 3 phases so 6. My controller has 4 posts before rect so its wye terminated. 3 posts would be delta. I would love to know which one is better suited (wye or delta, or your 6 post) for ebiking. Of course your 6 post can be terminated either way you wish, wye or delta very easily.

I was planning on using a sensorless bldc controller and a brushed controller for the field coil.
I have added some more pics and I sacrificed one for fun
This is how the wires are joined
once they are cut I am left with 3 groups of 4 wires these have continuity in pairs
With the pairs marked in color
