Problem with brushless setup

[norbyx]

Ok I have a brushless motor that works with no load... As soon as it has some resistance it stalls... Is it the motor or the esc?
Running it at full speed no load it gets extremely hot... Over 215 degrees...

Lots of questions to be asked.

What motor is it? Is it sensored or sensorless. Which ESC? What battery?

I'm guessing the motor is just shot if you let it get to 215 degrees... Typically it's recommended that a motor stay under 160F.

Chinese generic junk from the looks of it, quality parts last longer, and perform better.
No offense intended, but I would toss it in the trash.
Depending on what its going in just get a cheap trailmaster and a hobbywing 1080 for $60 if you want to spend less than $160.

I agree compleately, unfortunately I got this in a deal of a used car, and I thought it was in working condition, but once tested it had this problem. I can't undestand the cause of this.

Electronics and other some parts of china have a lot of problems , maybe rims or bumpers (ornaments)

I hate servos or tires fron aliexpress .... Cheap is usually expensive in the end

I haven't watched the video but from what you've described it sounds like the magnets are toast. Not repairable, motor is garbage if that's the case.


Once the magnets get overheated once they lose some magnetism, which means they pull more power to spin the motor, which means they got hotter, which means they overheat again and lose more magnetism, and it goes on and on progressively getting worse and worse each time.

This is why it's important not to overheat BL motors..

Ok so it's the motor. Well at least I know what it is. Thanks for the help everyone..
