Kde 4215-465 bench test. Shocked by results.

I would stick withe the KDEs because of the pole count

 

Most likely, that esc is toast, or has been damaged. I would only use it for testing from now on.

 

I have discussed this very subject with CC and they stated that there is really no way of knowing if the esc has any damage once you hit the over temp, or over current alarm/protection.

"Controller temperature must never exceed 100C (212F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC’s operating temperature."

 

Normal operating range of temp for KDE ESCs is 150-220F by the way- check out the video on the KDE website here, Episode V.

 

Correction, I don't agree with those temps at all. To each his own. CC protection is at 270F, and they have been making esc's a lot longer then KDE

 

Testing @ full throttle is useless because we never go there in real world usage.
Also own the 4215 465kv with T prop 15x5 (13.2kg @ hover 76A 6s )
More then advertised! but less then other brushless motors

 

Yes but very difficult to compare due to various parameters; test setup, location, room temp etc.
Correct octo > see avatar.

 

Hmm. And I was looking at getting these motors next.

 

When you selling the 55esc

 

I think the point is all about having relatively accurate tech specs. Lacking that a logical decision process is impossible. BTW I found some similar discrepancies in some T-Motor product data. Seems the industry tech standards have no standards. Lord help them all if they ever have to submit to ASTM testing.

If you size your esc by the KDE4215XF-465 motor specs (65+ amps) you would see that only the 75 amp escs will work with some headroom regardless of what prop, or voltage your using.
