So need a bit of help
Have these carvon v4 sd and one motor makes a weird noise
This noise gets amplified when riding above like 15mph
It is some sort of krrrrr noise which is really annoying and loud
The resistance is reasonably high in the motor
95mohms compared to 35 on the other
What is the best way to work out the issue and to solve it
@kook I know you fixed some carvons
Did you ever have this issue
Thanks a lot everyone
Please help if possible
Looks like the windings are going bad? Any thing else to differentiate the motors?
Will send pics in a min
What would it look like if the windings are bad?
Any sign of fracture or abrasion, so shiny bits of metal near moving parts or wires that are split…just very carefully inspect everything
Also get a multimeter and check the resistance between all the phase leads (3 sets per motor)
yeah will check resistance
nothing visible is the issue
also someone suggested trying bldc could that make a difference
BLDC should not make a difference if the motor is actually damaged, only if the motor detected wrong or something of that nature
yeah ok
looked and couldnt see any visible problem
checking resistance now
Disassembling the motor reassembling it and re-detecting should be equivalent to running bldc
k thanks very much
gonna try a couple things and see what makes a difference
i will be so annoyed if these carvons are dead
do you know by nay chance what motor they used in them?
Older ones are rewound sk3
yeah not sure about these though
i beleive @b264 might now
also for some reason the bit to measure ohms on my multimeter is broken so is there a different way to measure
i just changed around the phase wires and it seems to have got worse
even on the bench it is now being real weird
V4 carvons are made from koolwheel hubs iirc
oh ok
so is there anyway to reasonably easy replace the stator
Not a question I can answer, but my guess is probably not 
Ah ok shoot
Guess I have lost a pretty penny then if I can’t work out how to fix these
I bought these from @moros who said they worked fine
I pmed but if he doesn’t reply then I guess gonna have to make a charge back
Maybe give that guy some time to respond…
