7xl super hot!
 

Ok so current setup is a 7xl, MMMv2 and a 4s lipo. Running a revo, locked into 2nd, standard ratio, 18/40 gearing. Motor is hitting 212 :surprised: , MMM fan comes on every once and a while, and batts never see above 100, currently have mech. brakes. Im not totaly concerned about blowing it up, as id like to get either a CC 2650 or a Medusa of some sort. Anyone experenced these temps and had a motor last. I guess im just wondering if i should expect it to die sometime soon. I've ran it 2 or 3 times and no mojor issues except heat.

Sounds like you're geared pretty high- those temps are not abnormal IMO.

That rotor is going to demag at that temperature...only a matter of time.. i dont give it long.

Lol thats what i thought, the motor was even hotter with a 16t on and i dont have anything else but a 20, and dont want to even attempt that. Im pretty sure im going to go after either a 2300, 70mm medusa, or a 2200 60mm one. Any input on those is much appreciated.

Stick dat 20 toother on 'er for a little 'fun'

If the motor starts to demag, it will pull more and more current for the same output until the ESC and/por batteries start to complain. I would take it easy until you get a different motor...

I'd say it ran over temp once, and now as it's damaged, it'll do it every time no matter what you do.

Maybe hunt for a replacement rotor, see if someone has damaged the windings etc make a good motor out of two dead ones.

7XL is toasty motor regardless- stick a 70mm 2000-2200kv item in the truck and you'll be much happier.

Hmm, ebay time for the 7xl. Get your 50-60 bucks and buy a 70mm medusa, something like a 2200kv model. Or the cc neu 2200. Either will perform leaps and bounds better than the "spinning toaster of death" (gotta love Neil's phrases!)

Yea im going to try to run this thing until it dies, do they blow up or just get really hot?

I wouldnt recommend doing that- the magnet will get weaker and weaker, causing the motor to pull more and more current- you will kill the esc and batts before the motor in all likely hood. When you run it next time, if its getting that hot in a very short space of time, just stop using it; you now have a really cool fridge magnet.

used to run the 7xl and it would run in the 180 on a cold night....Nothings gonna change though....its just a hot motor.


Are you running a motor clamp? if not the endbell will pop off probably...but otherwise it will jsut continue to get crappier and eventually the magnets will seperate and become a $70 paper weight:yes:

I am running the RCM Heatsink, and i even put a slew of cooling paste on the motor can and heatsink. Im going to pull it out tonight, and most likely wait on the funds to buy a better motor. Anyone running the 60mm medusa in a revo? Im debating between that and a 70mm, any suggestions?

Why go with the 60mm when the difference is only $9?
The debate is only for Medusa and Neu/Castle.:lol:

^ +1. The extra torque and surface area (heat dissipation) from the 70mm version will be even more forgiving with gearing...
