High Voltage Motor

[Davwat]

Can anyone recommend a fairly cheep Motor which will run ok on 14.4 volts and preferably rebuildable,  as  I'm  running my TA01 Escort on 2 batteries!   I've made my own speed controller (2 speed forward and 1 reverse!) to handle the extra voltage and now I just need a decent motor!

The Car is Very Fast and standing up quite well but I expect to have to rebuild the gearboxes before too long!

For a cheap motor on 14.4v basically you are stuck with a standard 540,

even that will have a much shorter life. Race motors are designed to

run on 7.2v and although you could in theory run one on 14.4v you would

need to skim it and fit new brushes after every run.

If you really want lots of speed it is worth buying a decent high end

no limit ESC and a low turn modified motor. You will get the same speed

but with a lot less hassle.

Do you have any pictures of your Home made speed controller, I'm sure that there would be interset in this.

If you can't post em up here, you can PM me if you liek and I'll put em up for you.

Hi,

My first one which was just a modified tamiya one with some thick wire soldered to the back to help carry the extra current, but it caught fire so I've now turned to plan B.

This a car electric window switch so only has single speed forward and reverse. (all 4 wheels spin on take off and leave tyre marks on the tarmac!)  I've made a metal bracket to mount it to the servo. Its rated at 20 amps so should be ok for a while, I've had a couple of runs out of it so far

I've taken the advice of the other guy who replied to my question and gone back the a standard 540 motor, the car seems just as fast as before. I'll see how long the motor lasts!

I will post some pice of the car (That is if  I can, do you have to be a full member to have a showroom?) as I've done quite a few other mods including an aluminium front bumper and 2nd battery holder and a steel chassis strenghtening  plate. Now all I need is some tyres which done wear out so quickly!

Yes You have to be a full member to get a showroom, but, to be fair, I have found it worth every penny. so get yer hands in yer pockets!!  :-)

seriously though, if you can get the pictures anywhere on the internet, you can link to them in the forums here.
