Dismantling and repairing the motor :o

[jeff-jordan]

As far as I can remember, there are two sets of hall sensors.
One regular, the other one as spare.
And I think one set is at the inside edge of the stator, the other at the outside.
So if set-a doesn't get triggered, set-b should.

Unfortunately they are not consistently on one side or other.

I messed this up a bit. My bad.

I will have to try it and hope for the best.

If not, that will be a very thorough waste of time and effort. I very much hope it does not come to this.

An electronic solution would be to combine the two sets of Hall signals into one signal through some sort of conditioning board. It wouldn't even be very difficult but I'd need to know which wires do what. I suppose, in practice, if I have messed it up that badly, this would be possibly the cheapest solution.

Do we know what the wiring on the two sets looks like? I could do some tests, but at least I'd need to know which ones are the power lines, and what voltage they run at out of the controller?

If I can get that (power cable colours/voltage and output) I could do a circuit test.

Actually, I think the signal is half of the power voltage and then it goes up and down, so, somehow, to do that would need to pick the biggest delta to zero magnetic, then pick the largest magnitude.

Maybe, 6 op amp buffers, connect the outputs of each pair through a resistor divider to get an average, pluck the central voltage with a divider on the power voltage, and re-buffer that to FSD with 3 comparators to mid-voltage. That'd give a crisp full scale signal to the higher of pull up or pull down.
