I got a tacon 160 electric plane motor. its got 245kv and I'd like to rewind it if that would possibly to get it to have a lower kv and more torque.
I want to put a lot of resistance on it from a standstill and not...burn it out?

 

A quick google found this:
"The word turns stands for the amount of wire windings around each of the motor's rotor poles. The higher the number of wirings/turns means less top speed, but higher acceleration/torque."
Hence you'll need to find some enamelled wire of smaller diameter than the present wire so that you can squeeze more turns into the winding space.

 

Gearing? Might be the best option.

 

Gearing? Might be the best option.

For RC, high RPM is usually required.
The Motors are relatively cheap?
Max.

 

Its certainly doable.

I rewound this motor that i got dead and shorted on ebay:

When i got it the shaft was stiff as syrup and all of the windings shorted and melted, took a hacksaw to get the original windings off.

Yeah good point.

But then rewinding it to give lower RPM and more torque is basically the same effect as gearing. Gearing might be the easier option. Or buying a different motor.

Thanks. Looking for the lowest kv motor I can find instead of rewinding. And them more winds might not fit avoiding the gearing route if I can
