What Breaks Or Needs Replacement on Brushless Motors ??

[jacqua]

Hi All,
Just wondering what are the flaws of brushless esc's and motors? What are the typical things that break as far as the motor or esc goes? Does anything ever need to be replaced due to wear in the motors ??

Thanks

if you keep them cool then the only thing that will wear out is the bearings but then they last ages anyways.

i have had my hacker c40 8s for about 5 years now and its still a great motor its also rebuildable which means i can change the bearings if i ever need to.

So the only maintenence involved with brushless motors is replacing bearings every 4 billion mars years?

Pretty much. A shot of compressed air inside the motor and bearings doesn't hurt either, to get all the crud outta there.

The rotor can get de-magged over time and/or with exsessive heat.

Well, if you're talking Novak, the tab the motor wires are soldered on to is just as fragile as can be. Don't ask me how I know. But I've broken two so far. :mad:

I've broken none yet (I have motors with the older tabs, not the new ones though). What are they breaking from, landing on them?

No, it's due to the way it's mounted in a particular chassis. I'm currently racing a 5.5 in a TA05, and in that chassis the endbell sticks out the side. I've been taken out twice so far due to the standard rubbin' and bumpin' you experience while racing. I can confirm the aluminum motor guard doesn't help one bit.
I'm sure in a chassis where it can be mounted in-line, or at least entirely inside the chassis, it would be just fine.
