Re-Volt or Re-Wire?
That is the question...
The typical motor is mass produced and it's just cheaper for them to do a Single wind with a larger wire. But if you have a battery that can pull the amps and you want better performance your other option is to become a "tech freak" and literally take your motor apart, figure out it's existing wiring, then project what an alternative wiring might produce.
Yeah right...
Okay... so most people aren't as into as I am... but I have been playing around with a spreadsheet that would be able to make some guess about the resistance based on the "Turns" and "Winds".
Anyone who wants to play with this can download it and check it out. It's only as good as the information you have for the motor and so if you don't know your "Turns" or "Winds" or things like the length of wire per "Turn" then it's not going to be accurate. However, I have gotten some results that seem roughly in the "ballpark" for being correct.
Comments are welcome. (it's not perfect)
