I've read thru all the diagrams people have posted.& can't seem to find the diagram Im after.
anyone running a q.s v3 motor with crystalytes 72v 60amp controller..
thanks in advance.
So much time wasted on something I'd never trust anyway. With a few alligator clip jumper wires it's so easy to be certain of the correct wiring that all ebike builders should learn how to do it. I figure out the correct wiring of 6 phase motors regularly in just a few minutes. That's 2 controllers, 6 phase wires and 10 hall wires, so a common 3 phase motor I could do blindfolded. With wheel up and chain off (so you don't get whacked by a pedal with a valid reverse), using small throttle pulses so you can't blow anything, try color-on-color first. If that isn't one of the 3 valid forward rotation combos, keep either the phase wires or hall wires static (whichever is harder to change), and try the 6 possible combinations of the other set. One will be valid with a smooth quiet start and low no-load current. If it is a valid reverse rotation, swap 2, any 2, only 2 of the wires you were keeping static and find the correct combo of the remaining 5 of those you were originally swapping.
The absolute most swapping it should ever take is 11 total attempts. There are shortcuts, but why bother? It's better to understand the basic concept first, and that is that every phase combo has one valid hall combo, and every hall combo has one valid phase combo. Of those 6 valid combinations of the 36 possible, 3 are forward and 3 are reverse. There is never any need to go through all 36, or use a spreadsheet, or flow chart, or any of the silliness put forth by those who obviously didn't understand the basic concept of a 3 phase motor with 3 timing sensors.
