MT 4006-13 with ESC 32 / Motor problems

Postby fx44 » Sun Sep 14, 2014 1:54 pm

Hello,

i try to set up an MT 4006-13 with ESC 32
4S / Graupner E-Prop 12-6
testet Firmware :
esc32v2.0.0.r49
esc32v2.1.0.r57

i have done the Curent cal. starting with 10A and every further run +5A
up to the Motor limit (24A)

Slow acceleration is ok, but if try to speed them up fast the engine stops...

Anybody of you runs this setup ? or could you give me any ideas ?

THX
Felix

Hi Felix,

when calibrating my Tarot 4006 I experienced some problems related to the switching frequency (viewtopic.php?f=25&t=3268#p24272). I was only able to finish the calibration when running the motor at 21kHz. In addition, running it a max current was not needed! Do the voltage calibration first and look at the values. Should give you an idea what the motor is asking for at full throttle (should be able to reach it with the T-Motor 12x40 prop). Use this value as starting point.
Just to mention: the Tarot uses ca.13A at full throttle (with 12x6 E-Prop)--> not even near the max rated current!

Maybe try and increase
Code: Select all
ADVANCE   25.00
START_VOLTAGE   1.15
START_ALIGN_VOLTAGE 1.05
MAX_PERIOD   20000
SWITCH_FREQ   21.0


Please note this values were not proven! Just some parameters you can adjust and play with. BE CAREFUL WHEN CALIBRATING THE MOTOR!!!!

EDIT: Also look at this: viewtopic.php?f=26&t=1996#p9826

I had to increase the advance on the ESC32 when running a calibration on the mt-4006-13 so that it would complete successfully.

I actually cooked a motor and ESC when running with a 20A current limit with the APC 12x4.5MR on 4s. Turns out the 24A max current listed in the supplied table was for 3s operation. Running that current on 4s took the motor past the power it could handle and the stator wires melted.

I'm only running 11x4.7 props on these motors for now.
