the mini ev works at 24v with enough reduction. plan b runs them at 24v with a 34:1 reduction on the drive.

theres a drumbot on the way thats got a drum powered by 2x mini evs so ill let you now how it goes.

Silly Question:

Ive seen a lot of FWs with the entire drill used as the motor. Is this really nessesary ? I dont know if you can use the motor right out of the drill and attach to your wheels, or whether is has to run through a transmission

Gray, i dont think that those pancake motors, even with many of them will be upto the job. Have you looked at using bevel gears or somethong along that line to be abl;e to use the motor on its side and so use a larger motors.

i dont think so either.

I havent but as i said earlier my main problem is weight (then again when is it ever not a problem!)

i believe you said you needed a motor 5cm tall or so?

how about one of these fan motors -

there from mitsubishi TR magnas if youve got those out your way.

they are extremely flat at like 20-30mm tall and have ridiculous power at 24v. they spin a 1.7kg disk up to 4000rpm or so quite nicely in about 5 seconds tops. there a type of thingap motor in there design. only about 700g in weight.

david - yes you do have to run them through a reduction of some form. the drill is just easier to use. nothing stopping you from running it through a belt or chain drive but if you mean can you attach a wheels straight to the motor shaft then no... they wont have enough torque to move a feather.

now something like that would be good, pos on the heavy side but i was gonna upgrade to ni-mh from SLAs at some point anyways.

Im trying to source one on the net at the mo, any ideas where the best place to get one would be?

go down to your local scrappy, there will be loads of beefy old car fan motors. will usually only cost about a fiver. the smaller the car, the smaller the motor.

there made by nippon denso if thats any help, possibly look up a mitsubishi or spare parts place on the net. theyd be expensive brand new though.

would the dustin 1 motor be any good for featherweights? (http://www.robotcombat.com/marketplace_dustin.htmlhttp://www.robotcombat.com/marketplace_dustin.html)

Bit overkill, and WAY to expensive.

For that amount of money I can build a full geartrain and have electronizes on them. And that geartrain can pull a heavy.(unfortunatly, not for 5 minutes at one go at combat power)

yeah just thought it wud be a killer drivetrain IF i had the money (which i dont!)

[ewan]

Thingaps would be a more realistic drive train, yet again very expensive though.

Just wondering do i really need to support my drill on both side when i mount them eg one at geatbox and one at drill motor ?
