Any info out there about rewinding mass produced 540 motors?

    I've recently installed both a 27T and a 55T motor in my scale crawler, the result being one is too fast and the other is too slow. Therefore, instead of messing about, and also because I like to mess about, I was wondering if there was any info out there about rewinding factory produced 540 brushed motors.

    I want to experiment with that mid-point at around 35-45 turns so are there any guides about wire selection, winding methods etc?

    Cheers,
    Tom.

    rc4wd makes 35 and 45 turn motors for a low price. the winding wire would likely cost more then the rc4wd motor.

    I actually have some winding wire in the garage and, since I'm thinking of doing a 41T motor, one of the diameters is 0.53mm which will probably be perfect.

    If you have an electric motor repair shop, or a shop that works on irrigation pumps you might be able to ask someone there for some tips.
    Other wise I think it would be more time efficient to just order a motor with a closer turn count to what you want.

    Gave it a crack last night, stripped my 55T motor and wound on 41 turns of new wire. The wires always start off neat but get crowded and a bit messy towards the end. Some superglue to secure the windings and it works.

    I had previously measured the rpm of my 27T and the 55T, as it was, both with timing optimised to my liking.

    27T = 12,820rpm @ 5V
    55T = 5484rpm @ 5V
    41T = 8070rpm @ 5V (theoretical 9152rpm)

    Not bad for a first time!

    Tom.
