Using gold motors

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.

easy, by over volting them

Har Har bloody har.
I was more concerned about the poor Kid Tom who does quite well! LOL!

Gordon, did you modify the 12v golds front plate as suggested?

lol @ Grant

Has anyone tryed putting a fan or somthing onto the drive shaft of an over-volted gold motor to keep it cool? Like a bosch 750.

there isnt room inside.

Ewan ,Yes i did mod the front to take a 608 bearing.

Dave ,the fan inside the Bosch does next to naff all when used at a drive motor.Its never spininig fast enough for long enough.

By the way i also drilled holes in the casing of the gold motors but purely to save weight,i have taped over the holes.And i havent noted any difference in there performance.

putting holes in golds would not make much difference accept for weight as there is no fan to circulate the air through them. mounting in an obsorbant material is deffinatly the best way. Fans wouldnt make a large amount of difference even if it had them inside, Overvolting motors gets them majorly hot n seconds, far to quick for a fan to make much difference

Ive put a pic of Vertigo (as of saturday) on my profile. You may be surprised to hear Im putting the drive of micro-maul 05 (which went 6-1 at Rc Wars Wrexham) into Vertigo. Ive decided to stick with the gold for now (although I have modifed the gold with a bearing in the front boss). Testing will take place next weekend.

Looking good Ewan - just try not to kill yourself testing it P

whats the specs on that? well the spinner? looking good. especially if the drives as good as it went at Rc Wars.

Looks likes its going to be made of two 290mm dia. 8mm hardox disks weighing about 3.6Kg and driven by an overvolted Gold Motor, dont know what the gearing is but it sounds like its going to be a bugger to spin up quickley.

Looks like my plastic drum is going to take a beating again but this time its Ev Warrior powered!
