Are Velineon motors really this bad, or am I just killing them?

OK, so last week the stock Velineon brushless motor shattered the magnet in my Stampede 4x4 VXL and the VXL-3s ESC burned out. Wednesday, I purchased a new VXL-3s and 3500. I also purchased the VXL-3s fan and an Integy heatsink+fan for the motor. today, on the 2nd pack since it's been put in, the motor seized up.

both the ESC and motor were warm, but nowhere near hot enough that you couldn't hold it in your hand for an extended period. so this is the 2nd Velineon 3500 brushless motor i've burned up in 2 weeks. Are these motors really this junk, or am i overloading them?

i'm running Venom 3s 20c 4000mah LiPo's. love these batteries in my Losi SCTE, but are they too much for the stock VXL ESC/motor?

Wow - I don't know if this is normal, but if you do a quick internet search on : Velineon + Motor + Failure you will get a fair number of hits describing magnets cracking/delaminating.

Perhaps some other makes have similar failure rates, but there is definitely a magnet issue/weakness with that series of motors...

this is the first motor. it's out of warranty so i pulled it apart. the 2nd one seized up the day after i installed it, so i'll be sending it back to traxxas, and waiting. makes me reconsider wanting a MERV

Holy crap. That is impressive in the wrong way.

i just killed my vxl 3s, thinking about going to a mamba max pro race, the vxl3s is a nice esc with seemingly good durability but they just die too quickly to have fun with them sometimes

I've put castles and Novak motors to the point of making a blister on my finger tip with my lipo without any negative effects. I've never owned a velinion but with the abuse my systems take I'd try a diff brand.

Well, i decided to get a 1/16 Boss 302, and on the very first run with the included nimh battery, forward burned out on the XL 2.5 esc.

i love the traxxas line, but their electronics are pure shit :(

yup. Traxxas electronics are pure shit.

in about the last 2 weeks, i've had the following fail:

VXL-3s ESC X2

Velineon 3500 Brushless motor X2

XL-2.5 ESC

Mini e-revo steering servo

i'm just waiting for my XL-5 ESC to crap out on me now. no more Traxxas electronics for me.

does Traxxas do rollers?

Are you measuring temps? What gearing are you using? Generally magnet separation is linked to an over heated motor.

Are you free reving the motor? Thats usually what causes the magnets to come apart like that.
