how many hours would it take to rewind ? as someone mentioned above it probably cheaper to just get a new motor. i think paco sells a new motor for external controller for like 80 usd ? so i dont think anyone will pay more than that for a rewind of a blown old motor as a new motor also comes with new bearings etc and more important a new unworn rotor gear. which as it wears makes the motor noisy. so if the price is half a new motor 40 usd to rewind people may go for it vs just getting a new motor instead. Also bad idea to remove the temp switch as that protects the motor. can you put it somewhere else on the windings ?
most people that push higher phase amps will know they need to install a new temperature sensor ( the cyclone one is not very good anyway )
As i have mentioned in my last post rewinding improves so much its like having totally different motor the standard wire wind sucks the standard bearings suck if people are happy with that then buy a new motor if they want one thats way better then get it rewound and have all the bearings changed to way better ones ( standard motors run over 36v 960w over heat have a bad kv and the gears get worn quick because the standard bearings suck ) if you want to run higher voltages improve efficiency and have it last longer its worth it if you stick to 250w 15.5mph its probably not worth it unless you want to lower the wh/ mile
Hmmm, I am not sure how you got to that information of motor overheating etc, but I've been running the C3000W motor and a stock controller shunt-modded @ 6.5kW on 72V on my trike, no issues in 7000 miles or 1 1/2 years now (except bald tires)... I am about to do a motor overhaul at 10k miles and I will definitively inspect for wear...
This shouldn't be anything new: Rewinding the motor changes it completely, for good or for worse... all depending on the number of windings, wye, delta, double, triple wound, gauge... I've wound enough motors in my life to say: no thanks... I'll just buy a different motor.
And new bearings, etc... that adds up to the cost of the setup. But with the Cyclone 3000W priced at 330 bucks its sorta hard to beat...
In the end the C3000W is an inexpensive starting point... good to get you going, but it can be improved, same goes for mounting solutions... .. the controller, etc.
