Overvolting drill motors

[motty]

Not sure if I am going to use 9.6, 12 or 18 volt drill motors yet, but what would be the optimum voltage for these motors, I have heard that you should only overvolt by 50% is this correct. I will be running 100mm wheels

Re: Overvolting drill motors

In reality there isn't much point to overvolting drill motors as they are generally too quick as they are, however if you wish to overvolt a good rule of thumb to follow with all motors is to, as you said, run them at 150% of their rated voltage. This is by no means a guarantee that your motors won't burn out but gives you somewhere to start from.

Re: Overvolting drill motors

Has anybody got any thoughts on the best voltage drill to use ie 9.6 12 or 18 volt (before overvolting)

Re: Overvolting drill motors

id go for 12 volt drills then you could either go on a 12volt batt or 2x 7.2v in series to make 14.4v

Re: Overvolting drill motors

yeh, I want to know about drill motors as well, like how much faster do they go when you overvolt them if you use 50% more volts than your spost to does it go 50% faster

Re: Overvolting drill motors

yep thats right only over volt by max of 50 % to ensure the longevity of the motors (obviously over volting a motor can kill it)

thanks

Re: Overvolting drill motors

overvolting drill motors wont do much, they are generally fast enough as they are.

depends what your after

Re: Overvolting drill motors

even with 100mm blue wheels 500 RPM drill motors only go 5.9 MPH and I think thats to slow , were as 750 RPM Drill motors with 100mm wheels goes 8.85 MPH which is fast enough

Re: Overvolting drill motors

You'd be surprised at how fast drill motors go on their regular voltage. I generally don't bother overvolting them and just run them regular or if i do then run them with 50% or whatever on the sticks as they are too fast otherwise. Remember that 6mph is roughly 3 meters per second and the robot will get there almost instantly. That's a fair bit in an arena measuring 10m by 5m max or thereabouts

Re: Overvolting drill motors

ok I will just go for 6 mph then if you think its fast enough

Re: Overvolting drill motors

build the bot with the drills on regular voltage and try controlling it then you can decide if you wanna uprate or not

Re: Overvolting drill motors

ok I will do that
