Hello Guys


I have took one of the memeber advice to test the kv and as soon as i tested it the motor burned ! and at end i don't know even where to see the data i made during the test |!


i removed the pinion and as soon as i gave it full throle under testing kv mode it burned ,

the smoke came out from the shaft side , if i put picture nothing will show it look like new

by the way how i do the process of testing kv ?

what i did removed the pinion , put a tick on testing kv , return the wire to the receive and start car in a normal way , hit full throttle it smoked but anyhow i couldnt find the data

Man, that sucks! I sure as hell won't worry about what kv my motor is aside from ordering what I think will be the correct spec for what I wanna do. So long as my car goes fast and stays cool, I could care less what the actual kv specs are if it's gonna fry my motor!
 
Its the first time I have ever heard of conducting a KV motor test and it frying the motor, my guess is the motor he was using was way to high in Kv spec and it would have burnt out anyway......

What is it you think the software did to burn out your motor within a second? The motor PULLS any amps it needs. It wouldn't matter if you were able to feed the ESC with 1000A, the motor would still only pull what it requires. And an unloaded motor wouldn't require anywhere near what it pulls under load.

I think, as mentioned before, your motor was about to go out anyway. Whats the status of your motor bearings? What does the motor look like on the inside? Is it full of dust? What does the rotor look like? I've done the test on a MMM with a 1518 and 1717 numerous times without any issues.

If you're running a Castle motor send it and let them check it out.

EDIT:

Oh, have you checked temps while running? Castle says to keep the temps around 170f or 77 degrees Celsius and as an absolute max 185f. Going higher might cause the glue on the rotor to dissolve and the magnets to demagnetize. Once you've overheated the motor it will generate more heat due to the magnets being weaker and will be in the danger zone of overheating quicker than the first time. Overheat it again and it will overheat sooner and so on. It is essential to measure the temps of your motor. Even when you think you've got your setup dialed in.
