What compressor??? (I think you must have been talking elsewhere )

Nope, he said so above:

Woody, youre right about the fact that the motors use the same amps but the valve and the 24V compressor wont. They will use less. Because Im not overvolting them.

ah, I missed that... (slaps head...) but yeah, if your using a 24v compressor then no average booster will handle the current. Would it be possible for you to get some 18v or 24v drills, that would be a simple resolution to the problem, (running on 24v).

I run 14.4v drills on 25.2v in pimp 2 with no problems, the wheels are 90mm diameter and 50mm wide and it goes like stink (unless the disc is turned on)

So you can overvolt the 14.4V drills to 24V?

14.4v motors can generally be run safely up to 18v because above that voltage you can risk burning out the motor quicker it stalled or jammed for a short while like Pimp2 found out on Sunday.

Ahhhh the smell or resin/lacquer burning on copper windings, nice.

OK, thanks!

The motor only burnt because the wheel came loose and jammed against the chassis. I am going to replace it with another identical one because I am that confident in their ability to take the load.

Can you overvolt 18V motors to 24V without burning the motors?

In general any motor that has a continuous rating can be overvolted for a short period.

But something like a car starter motor has an intermittent duty rating and heats up very quickly even under normal circumstances and is not recommended for either overvolting or continuous running at its normal voltage.

So in my opinion ...you can overvolt your 18v motors @ 24v.

For anyone thats interested, I got the new Maplin suplement today, and they have a special offer on 18v cordless drills. £14.99 including all the usual toot. Free delivery on orders over £30 - so thats 2x drills and something for 2 pence please!!

Also ive noticed that most Woolworths stores sell a 18v drill/driver for £12.99 which isnt bad but i havent had chance to check them out yet. As im looking for a higher volt motor to replace the 14.4v ones in Conundrum, so i dont need that extra 12v SLA battery and it can all run off of the 24v NiCads.

From previous expirience, the Woolworths drills are exactly the same internally as challenge, or nu-tool (the cheap) drills.

From our experiance the only problem weve had with runnign 9.6V and 12V drills at 24V with 125mm wheels was with the gearbox. Run into something too hard and snap a tooth off a nylon gear, the robot drives around a bit more then the broken tooth gets caught between gears and jams the gearbox. It only then you say bye bye to the motor.
But we had one 12V motor running at 24V with that 125mm wheels the slipped out of its mount, twisted the connection wire, which pulled it into the robot. This pulled the wheel against the chasis which jammed the motor. The motor was stalled for the rest of the fight and flatened the batteries very quickly, but didnt burn. Also our Victor 883s didnt even get warm.
