problem with mm overheating... fan?

C to F conversion: F = C * 1.8 + 32
F to C conversion: C = (F - 32) / 1.8

0C is 32F...

I don't believe that actually. Here is the specs of the melting point of aluminum.
Name: Aluminum
Symbol: Al
Atomic Number: 13
Atomic Mass: 26.981539 amu
Melting Point: 660.37 °C (933.52 K, 1220.666 °F)
Boiling Point: 2467.0 °C (2740.15 K, 4472.6 °F)
Number of Protons/Electrons: 13
Number of Neutrons: 14
Classification: Other Metals
Crystal Structure: Cubic
Density @ 293 K: 2.702 g/cm3
Color: Silver
British Spelling: Aluminium
IUPAC Spelling: Aluminium

With that said, the solder on the wires, or solder anywhere in the esc would not last, nor would the circuitry, FET's, BEC, any of it.

I was close!

Doesn't the type of aluminum affect the melting point (2032, 6061, 7075, etc)?

newe: Yeah, you were "close", but I was just letting you know the formula for future reference. ;)

No prob....all well and good sir. I usually use the burnt finger technique! :005: :013:

And yes, the grade of aluminum does matter when it comes to the melting point. The better the grade, the longer it takes to melt due to the higher temp it needs to be at. this has to do with the alloys in it to make it stronger. But the point I was making still stands I would believe. The info I sent is general and is used as a guideline.

I don't mind the burnt finger technique... as long as it belongs to someone else! :)

I thought the type of Al would make a difference on melting point. Maybe BP used a really low grade aluminum?

Then the quality would have been a tad more then solder....:eek:

lol. True.

wow im lost.

Sorry about the hijack!

[glassdoctor]

I think he meant that the esc had a nuclear meltdown... as in burned up. A shorted 1000w battery can do that :)

According to castle, 200* should be the upper limit on both the motors and esc's

[Sylvester]

Ive never gotten my esc over 130F! The melting point of the aluminum is no where NEAR our problems when it comes to heatsinks... near the 200F mark for a while would be enough to "fry things up!" ;)

[jollyjumper]

the 100C i said may be a little too hot then.
but i think it was castle where i got that from.
100C is 212F, correct?

[glassdoctor]

I still think everyone missed the joke in his post... I'm sure he knows 200 won't melt alum. Imagine an esc becoming arc welder... a dead short. That's what he meant I think.
