Smoke=dead?

my esc smoked for umm 3 sec, is it dead :(

[R3VoLuTiOn]

prolly

<--- Votes yes, and suggests figuring out why before you try again, if it's still alive it may not be the next time you turn it on.

well correct if ime wrong i hooked up a normal 6cell battery to a small micro motor with a duratra 16t motor esc, is the motor like not using all the power cause the esc to over heat alot...?

[rocknbil]

The micro motor probably doesn't "burn up" enough energy and the effect is close to taking the ESC motor-leads and just shorting them out, driving all the electricity back to the ESC.

Highroller you out there? Elaborate on this one . . . .

your short circuit theory is interesting, but it doesnt seem to be quite right d00d, i have run very small motors on airplane ESCs rated much higher than the motor and i have had no trouble....... but then again, im no expert :P

[rocknbil]

What was the power source for the plane motor, and what kind of motor?

[highroller]

It depends on the amperage rating of the ESC and when it was made. Motor could have a higher amperage draw than the ESC was capable of handling - providing the wires weren't connected wrong. My old Futaba ESC will do that with 24degree stock motors, only rated at 85 amps going forward and backward using todays motors it will smoke-but works fine if I stop and let it cool down.

The ESC may be fine you'll need to use a volt meter (digital better) to check it (don't hook the motor to yet) check voltage of battery - hook to ESC and check the output voltage on the motor wires, operate the radio thru the full range of throttle/brake/reverse(if equipped) voltage should only drop a few tenths due to resistance, if volt meter shows a big drop or no voltage something has burned out. Usually Mosfet equipped ESC will burn out the brake/reverse mosfet but only forward will work.

highroller what about his second post, hooking the ESC and 6-cell to a micro-motor? Whadaya say, more draw, or not enough resistance, what?
