Struggling to solder carisma motor
 

Afternoon
I do not seem able to get solder to stick to carisma 4500 motor wire.
I have soldered quite a bit and never had this problem.
The solder will not bond?
Tried everything.
Anyone got any ideas.
Thanks.
James

Flux on wires it cleans before soldering

I have put plenty of flux on it still will not take. It's really strange?

Try some different wire sometimes cheaper stuff does not like solder unless lead based

I am literally trying to solder the carisma direct to the esc. Solder sticks fine to esc and the battery wires I have put deans on etc etc but the carisma motor wire just will not stick. Even when in through the esc holes it forms a nice round solder joint but the motor wires will just pull straight out. No bond at all?
As I say very strange? Almost as if the motor wires are corroded or something.
I wish I had never tried to make it look neat and left the original connectors.
Is it possible to open up motor and attach new leads?
James

Hi
its because the motor wires are covered in a type of insulating lacquer
that is applied to stop the wires shorting in the can windings, you need
to scrape back the wire with a hobby knife or small file (or dremel)to remove it
this is quite a common problem, and can cause cogging if you don't
get a good connection

Thanks dom.

You could try dipping the ends in acetone if you have some depends what type of enamel it is. Or burn the enamel off
