Title: motor cut off at 50% throttle with continue beep Post by: jnsahil on August 16, 2016, 08:05:38 PM hello frnds
my plane got crashed last week, after that i checked my all electronics evn motor with 10-20% throttle, every thing was ok. but today as i try to fly my plane motor stop rotating at 50 %, and its heating. my winding turned to black (little bit), important -battery is charged and ok -winding resistance of motor is ok (1.3 ohm each) -there is no vibration or jamming in motor - its running well upto 50% plz help me Title: Re: motor cut off at 50% throttle with continue beep Post by: avesh on August 16, 2016, 10:25:23 PM Might be timing issues or issue with your esc. Try changing your esc and see if it happens again. There is a possibility your esc might have screwed up your motor.
When the receiver has a brown-out the Electronic Speed Controller goes into "fail-safe" and stops the motor from running. See if your servos still work when the motor cuts out. Does your motor start smoothly or starts twitchy ? what current is it drawing and what voltage ? Title: Re: motor cut off at 50% throttle with continue beep Post by: jnsahil on August 16, 2016, 10:49:44 PM i din't check the voltage or current but some important issues are remarkable as
- motor takes current more than normal bcos it start heahing -before stopping motor an unusual sound(humming) produce from fuse lag just a couple of inch back from motor mounting -as the motor stops it start a continues beep like peeeeeeeeeeeeeeeeeee til i pull back throttle to zero -and last it happens at exact 50% -motor works up to full trottle without props but produces humming sound at higher speed i hv reprogrammed esc. is there any motor bearing or shaft issue Title: Re: motor cut off at 50% throttle with continue beep Post by: avesh on August 16, 2016, 11:05:00 PM i would check the bearing and the shaft. The crash might have damaged them. The peee :giggle: sound might be from the bearings. I have had same issues with my 3800 kv motor at high rpm's.
Please specify the make model of motor and the esc. Title: Re: motor cut off at 50% throttle with continue beep Post by: jnsahil on August 16, 2016, 11:15:34 PM Hobbymate HB2806 brushless motor, 1450 Kv
Hobbywing 30A speed controller but i think problem has solved bcos after 20-30 testing my motor start smoking (lol) Title: Re: motor cut off at 50% throttle with continue beep Post by: avesh on August 16, 2016, 11:19:03 PM RIP :salute: .
Just be careful with your hobbwing esc, it might have burned your motor. I faced the same issue with compass warp motor, i was lucky enough to land it. :hatsoff: Title: Re: motor cut off at 50% throttle with continue beep Post by: jnsahil on August 16, 2016, 11:27:48 PM it will also burn soon bcos motor windings got black
