Spinner motors

[glen]

ive heard that slot car motors can be used as antweight spinner weapon motors.

is this true? and what sort of voltage, speed, torque am i looking at in a typical slot car motor.

Spinner motors

yes it can be used.

there is a link to a good one (stinger) if you scroll down a bit. I will leave it to the spinner guys to give you some better info.

how about one of these? http://www.sussex-model-centre.co.uk/item.asp?ID=2572http://www.sussex-model-centre.co.uk/item.asp?ID=2572

400-700 gram?

for an ant?

its weighs 43g
but you need the proper controller bit slow for brushless there are better out there

I have just got a brushless motor from the USA that does 65000 revs per minute at 12V. I have no way to verify this but it really does sound fast. Now all I need is a disc balanced enough to run at that speed.

Are you about to run an ant on 12V?

Thats not unusual Danny.

Pete, I think it might be worth constructing a dynamic balancer- there are some good plans around on the web, most seem to be an attachment built to be used on the lathe bed- model gas turbine sites are probably a good place to look.

I was considereing getting back into ants (I havnt built anything since WS4) but Im not so sure I will now :-p

Aha okey, can the reciever and servos handle that current or ist there a seperate battery for the reciever?

Most ants that use 12v (12.6v if you want to be accurate, 3 x Lithium polymer cells) are spinners, and as such have a ESC for the weapon motor, this normally has a voltage regulator onboard, which you then use to power your reciever and drive servos. If you want to run more than about 6v in an ant without an ESC, then you simply take 2 lines off the battery, one of which goes directly to whatever it is youre running at the higher voltage, the other of which goes through a 5/6v regulator to the RX and other servos.

I see

Some servos can supposeldy take it, usually the larger ones. The micro servos get upset above 6V really. Some have had success at 7.2V. It all seems a bit hit and miss really, but yes, the rest of the ant is run off the BEC

Eddy that sounds like a good idea. I have a static prop balancer which has been good enough up to now (max 35000 rpm) but if I do get vibration problems I might just look into that.

yay my stinger arrived today

nice pic of it sitting on the new ant (wheels are just there to give and impression)
