That's not too bad. Although 190 F *is* hot enough to congeal an egg ... but not hot enough to destroy most linear ICs like a regulator (typically rated to 150C or so for junction temperature.)

jwatte, seems it tops out at 190F with heavy mowing, hilly terrain. when on flat blacktop 175F.
the only problem with having unlimited batteries, is you then end up adding things like computers,
compasses, gyros, GPS, ultrasonic.
... radars, railguns, electric arc based armor, ...
:-D
jwatte, I was thinking more like big 110vac inverter for backup power for when the lights go out, or a 110vac weed wacker.... radars, railguns, electric arc based armor, ...
but, lidar looks like something that would be fun to play with.
jwatte, lucky for me I got all that kind of stuff out of my system as a youth.... radars, railguns, electric arc based armor, ...
my first job in electronics back in the mid 70's was fixing radar guided missiles for the army, so now I think
shoveling snow and cutting grass, but my mind is wondering towards automating farm equipment.
with the failure of 2 external fan alternators in 2 seasons I installed a internal fan type.
it does run much cooler (160deg).
Why did you stop updating this topic? You have a fluent expression. Did the fan types you installed managed to cool?Originally Posted by Tommy_T

danniel, yes the internal fan type alternator did run much cooler then the external fan type.Did the fan types you installed managed to cool?
With the external fan type alternator I would have to monitor the alternator temperature very closely
and stop frequently to let it cool down before continuing mowing to keep from burning it up(220deg).
with the internal fan type alternator installed I was able to mow continually.
but even with the internal fan type alternator the 500cfm blower are still required to keep the alternator
within operating temperature.
That's actually pretty crazy. When a car battery is low, the alternator will have to produce a fair amount of current for a fair amount of time; I wonder if you can kill the alternator in your car by doing that on a hot day?but even with the internal fan type alternator the 500cfm blower are still required to keep the alternator
within operating temperature.
jwatte, if a cars cooling fan failed, and something in the charging system shorted to ground( causing a constant 40Amp draw)
and the car moved at very slow pace(lawn mower speed), I could see the alternator failing.
