I think Ill just use a big lump of ali milled out to accept the motor body for both mounting and heat conduction, shouldnt cause any efficiancy or EMI problems.
So far Ive just modded the leads to 6mm2 silicone cable which is nice and beefy compared to the weedy cables which came with the motors.
Ill hopefully put a gold mod page on my site soon. Ill try and get my hands on some 24v golds asap
sounds kool. would a steel ring aroung the motor casing increase the power of golds?
Has any1 tryed this?
I have thought about that as well, if i get time ill give it ago for next event. I know drill motors have a extra steel sleve that improves the performance. I suppose it depends how effective the casing already is and wether it will make much differance.
The extra steel sleeve on the drill motors is actually to be slid over the ventilation holes during manufacture so no crap or swaff goes inside the motor, its also handy for when you have to drill around your motors :)
The steel ring can enhance the torque of the motor, by containing the magnetic field inside the can.
Easy way to see if the can is thick enough is to use a thin piece of steel. If it sticks to the can, the magnetic field is not contained entirely, ans therefor loses a little force. The stronger the attraction on the outside of the can, the worse it is.
Ahh, does that decrease the speed though? I have been running a small motor in my RC Plane and it says to remove the ring but it doesnt say why. (I guessed that having one on increases the torque, and so would it decrease the speed)
Is this what happens?
Grant, looking at it logically, if the magnetic field is reduced then i would say that the motors back EMF is reduced and thus the motor will run faster to further increase the back EMF until it balances out.
Hi Ewan ,If you are overvolting 12v gold motors they wont get hot, theyll get VERY hot.
But then it does depend on the gearing,current limit (if any,slas should be ok),and the way you drive it.
Stiff breeze 12v golds at 19.2v (using sub-c nicads) with a 40amp current limit,5:1 gearing and 80mm diameter wheels.
So far Ive metled the armature insulation and had the armature spindles come loose.But im blaming Toms driving for that! :)

LOL! AWWW!!!! OH Dear!
Gord - how could you. LOL.
Mr Stu
easy, by over volting them:)
