Winding Issue

[Tais]

one of my fans has 2 winding cables cut sadly, the winding works perfectly fine except for that part when i tested it with the ohmmeter.. in the provided image, the upper right and lower left threads are the current carriers.. the winding is done counter clockwise.. the lower right and upper left cables are currently idle.. the pic below explains what i am trying to say



i thought of doing either one of the following instead of rewinding:

connect the lower right to upper right and upper left to lower left resulting in a small opposite direction in between by lead or tin soldering it since they are very easy to connect

connect the upper right and lower left threads together by brazing and have some idle winding in between which is a very small fraction

connect both cables by brazing


the problem here is that brazing copper with each other is very risky and i am worried it may destroy the insulation.. and cables from the right side to the left side is barely reachable which will make it hard to connect

I would take it to a motor shop and see if they can splice it.

I tried soldering a broken winding once, the heat from the winding melted the solder once it was running.

do you recommend connecting 2 cables in a way some coil would have current flowing in the opposite direction (a small fraction of a whole coil section)?

Only if that is the only option for repair.

i ended up doing that since one cable got snapped while attempting to repair! the resistivity (with ohm meter) is slightly less than its original value which is around 88 (avg of 3 other identical fans i have), this one is now around 100 ohm
