Motor cooling???

[crawler_king]

Ok so the motor in my scaler heats up and seems to stall on me.. I have torn apart an old PC in an attempt to locate a fan and found a nice intel one that seems like it would make a great "radiator" fan.. even has the side peices... now my problem seems to be where the heck to mount it and route the airflow.. as well as how to power the little bugger....
I thought about right in front of the motor but I dont think I have the space.. that and the fact that I would have to "open up the front grill.... which would be a pretty cool scale touch...
I have no idea what the cfm of this thing might be.. but hope that it will do the job...

Re: Motor cooling???

hook it up to a 9 volt battery, i bet it will work.

Re: Motor cooling???

Like CJ said, micro switch and a 9V battery. I also have a 540 sized AL heat sink you can have if you want. Can't use it on my puller motors.

The can heatsink is the way to go...it will pull the heat from the can...but first of all you need to find out why it is heating up...

This is very true. A lot can be said for having the correct gearing for your truck, and driving style. That is why even geared down, I needed to have the heat sink on the 45T in the 2.2 as my truck was on the heavy side for the motor at 7.2 volts.

That heat sink I have does work, and will help as long as everything else is set-up well, and the motor just isn't getting the airflow required.

The 7T puller even as awesome as it is, got warm on 7.2V in the super. That was with the GD600 in, that motor just didn't have the grunt at that voltage to handle the big pig.

The 10T puller can handle Fat Girl, even without the GD600. This is due to the torque in the 10T and going from 7.2V to 11.1V for power.

Jay,
Make sure that you are set up right. If something is wrong with the set up...the fan is only going to prolong the inevitable.

Good Luck

Re: Motor cooling???

yeah 2nd that, the motor should not be heating up that badly. something is out of wack!

Re: Motor cooling???

Part of me is thinking it isnt getting enough fresh air with the fender wells, and close proximity to the hood... just not enough air moving around.. I noticed that this motor has 3 little diodes or somthing on it.. looks almost like a cluster of fat little ticks.... where as the old 55 t integy didnt.. also dosent have any cuts in the can like the integy motors do... I'll be over at AB tommorow picking whomevers brain.. dont want to stall at the comp!

Re: Motor cooling???

sounds like it has capacitors on it. that wouldn't make it heat up. i dont think, they are there for interference purposes. glitching stalling ect!

Re: Motor cooling???

racking my brain as to why it would be heating up.. the leads are on the right contacts, everything seems kosher.. ugh... think I am going to try driving it around naked, the truck not me, and see if I can get it to heat up....

Those are the caps, and they are good for the motor. You just might not be getting enough airflow over the motor.

dude that just sounds dirty!!

Re: Motor cooling???

ok.. so went down to AB and put a rooster into the ol scaler, then Lewis came out and we hit the rockpile out back.. she works pretty good, motor took alot longer to heat up but it still did it.. Might have to see if there is another GD type unit with a larger reduction than the 600....

Re: Motor cooling???

that sucks bro! are you sure all the gears are meshing properly? nothing is binding or to tight?

[Lewis]

Re: Motor cooling???

no the truck spins freely. no binding
