Bosch 400 motors

[woody]

2 motors wired in series AND mechanically linked by chain , belt or gears...or even shaft to shaft effectively making ONE motor.

One of the problems you get with wiring in series, as i understand it is that you will be pulling the total current for both motors through each, say if the motors are pulling 50amps each than there will be 100amps flowing through each motor. I may be wrong on this though.

i would say its back to the drawing board, but these motors are fitted lol

Thanks for the kind words on the chassie Adian. It wasnt far off from completion. Around half way there.

However I calculated the speed of the motors as if they were running on 24volts so it was quite a hefty gear reduction as the motors would be going so quick. However once I realised I had to lower the voltage the robot would go really slow. Also I was running a linear actuator inside the robot which needed 24 volts so I would need an extra power supply to the weapon. In the end I just decided to scrap the build and leave it till funds were better and build a better one. Which will be Carnifex when I eventually start it.

However the old heavy weight chassie has found a good use

I might be using that chassis for my heavy, so it may yet roll into battle.

The santa hat of doom!

spent the day in the workshop today, after alot of thinking/measuring and weighing decided to fit 2 750 watt bosch motors which shouldnt be too tricky of a job, and remove the 4 400watt motors. this robot has 4 wheels, and i dont know if we should mount 1 motor at rear and one at front, or mount both at rear, (it needs to have the four wheels) but im wondering how will it drive with 2 motors at the back, and the front just free wheeling. (WOULD IT TURN?, i really doubt it) the wheels are similar to kart wheels. i didnt want to run long chains from rear to front if i didnt have to, just because im worried of snapping chains/reliability issues.

...possibly a pointless question but would belts cause the same issues as chains?

[ady]

i think belts would be better yeah, alot more give in them, just wondering how much work i would need to do lol. also chains im better with as i can take links out to get the right length, but belts maybe a bit harder to source..

You should be able to find any length of chain, belt etc etc on there and if not they might be able to make you something custom
