thanks
but i have had NO problems with any esc's i have done in the past for others or myself ....
others i have done have been working for over 3 years sofar with no problems .
i do know what needs Proper heat dissipation and some other factors.
other things have been added to the esc for reasons of safety and longevity.
i have been doing electronics for far to many years to go about things blindly.
But thanks for your concern.
the above link was a Fun read
but only applies to a device that is used in a way that it was NOT intended to be used OR was of a Bad Desing to start with
or used out of specification....
like "More brake load /force" than the fet's can shunt to gorund and with that type of electron power energy flow or "EPE" as was put ..
look at it like this ..................JUST an EXAMPLE >> if a FET can handle 5000 electrons per ms shunt to ground and you force 20000 to it just what do you think will happen?????? you will end up with a electron saturation within the device ...and in a short way to say you will get your Magic smoke.
99.5% of the time this is the cause of the ESC letting out the Magic smoke people usen a motor that draws more current and Or present more shunt load than the ESC can TRUELY handle over a period of time leading to a catastrophic failure of the FET's in the ESC.
i think its funny when i see people saying ....
when you apply brake the power goes back to the battery on a rc.......
NOT!!!!!
the motor can otuput WAY OVER 10amps on brake
so basicly thay are saying thay are putting OVER 10amps of power back into the battery...OMG.. "BOOM"!!!
the brake load is shunted to ground not put back to the battery......
we are not talking like a hybrid car here a rc esc is very simple in its Desing.
Just Fix It !!!
