Hello everybody,

I have some questions about an experiment test that i made with my propulsion system. The test was to test the propulsion force that the motor can make and the power consumption. I this test I have used:
1- DC brushless motor: Alien 6374 Outrunner brushless motor 170KV 3200W ( http://alienpowersystem.com/shop/63mm/alien-6374-outrunner-brushless-motor-170kv-3200wa/ )
2- XERUN-150A-SD Sensored Brushless ESC for 1/8 Car ( http://www.hobbywing.com/product_show.asp?id=238 )
3- Voltage and Current Sense - 180A ( https://www.sparkfun.com/products/10644 )
4- 2 x Gens ace 5300mAh 11.1V 30C 3S1P Lipo Battery Pack to provide a 22,2 supply voltage to the esc (http://www.gensace.de/lipo-battery/helicopter-lipo/gens-ace-5300mah-11-1v-30c-3s1p-lipo-battery-pack.html )
5- Kaplan KC propeller 150mm

I have tested the propulsion system in different speed ranges from 1% to 100% But the results of the test were very strange and i didn't find an explication for the current values the motor don't support more than 80 amps.
The list of numbers below represent some values of the log file.
The speed range from 0 (full reverse) to 1 (full forward) with 0.5 the middle point.

Please if there is any one who can help me, I will be grateful.
 
I dont' really understand your logfile, unless it represents time before you turned the system on, as the Volts (presumably V at the controller's battery input?) reads 0 for a long time at first.

Presumably 0.5 on the motor speed means the motor is not spinning at all?


I don't see how (assuming exactly the same load on the motor) that you could get it to spin up to max speed (0.0) with only ~3A the second time around, but take almost 120A the first time.

If it had a much higher load on it the first time, then it would make sense, but only then.

Maybe I just don't have enough information or I don't understand the already-presented information?
