I bought this new ESC from Fliermodel http://www.fliermodel.com/en/prc-show.asp?id=694
Mass = 1.52kg (as shown in photos below)
L x W x H: 7.8" x 4.3" x 2.0"
Many of you will likely want to reply that this thing is crap and will not withstand much power. And that might be so. However, please refrain from replying if you do not bring value to the discussion. There will be comparisons made with the testing of the 420A ESC https://endless-sphere.com/forums/viewtopic.php?f=2&t=44897.
I would love to get the really smart people with EE knowledge to chime in with what this ESC could be capable of doing given the info we have on this unit and past units.
I contacted the reps at Fliermodel and have been asking them for test data. One thing they have said is this can only do 25kW max. So 90V and 500A is not going to happen. I'm hoping for 80V and 250A for an input power of 20kW. Here is the test data they provided me using a 1.4m prop (still trying to confirm the details). As you can see, their battery is unable to support the amps. I hope this is why they did not push it further as that was about where the 420A ESC died.
Volts, Amps, Power (W), Thrust (kg)
86, 36, 3096, 21
82, 59, 4838, 30
78, 90, 7020, 38
Since the rep at Fliermodel strongly discouraged anything over 22S, I asked if it is because of the Mosfets and she said yes. So, the MOSFETs are likely 100V n-type, maybe like this one http://www.futurlec.com/Datasheet/Transistor/IRF540.pdf
In the image of the MCU board you see "48mos", does that mean 48 Mosfets? The side image does seem to show about that many (8 x 6). Notice how the IC labels are all scratched off. A total of 20, 100V 330uf capacitors.
Test results will be posted once I get the prop, motor and battery pack.
