Title: Avionic 1818 micro brushless motor Post by: mks on March 28, 2014, 08:59:40 PM Hi friends,
I bought a micro brushless Outrunner Avionics 1818 (along with a 500 mah Lipo, prop etc) from RC Bazaar about 10 days back. I tested the motor at arrival and it ran perfectly well on my 25amps ESC with the supplied Lipo. I started building a thermocol small plane for this motor.. but as I fixed this motor on my plane it refused to take even a full revolution and started jerking to and fro.. I have tried the esc and motor combination to my other outrunner motor which runs okay.. I wonder what a pethatic motor is this which could not even survide a for second run. there was no mis-handling on my part on this motor as I carried this motor with due attention. I contacted RCB but they are asking to check the ESC and say "this happens due to insufficient current draw" I am very disappointed and don't know what to do.

:banghead: I am trying once again Title: Re: Avionic 1818 micro brushless motor Post by: rastsaurabh on March 28, 2014, 09:02:32 PM check the wires of the motor... there might be a loose connection... or one of the winding may have been broken...
test via multimeter Title: Re: Avionic 1818 micro brushless motor Post by: mks on March 28, 2014, 09:17:12 PM I have checked the gold connectors they are okay
cirtainly will check the continuty .. maybe something went inside the motor .. but the wires inside are so flimsy to break so easily without any use? what a hopeless motor is this. Title: Re: Avionic 1818 micro brushless motor Post by: mks on March 28, 2014, 09:18:21 PM sorry sorry..
I meant "maybe something went wrong inside the motor.." Title: Re: Avionic 1818 micro brushless motor Post by: kiran rc on March 28, 2014, 09:19:14 PM Is this motor series good ???want to buy one

Looks like the ESC does not see all three motor leads could be due to a motor/ ESC wiring/ connector issue had this one before.. Title: Re: Avionic 1818 micro brushless motor Post by: v2 eagle on March 29, 2014, 01:02:17 AM This might be your problem,
the rear shaft protrudes a little outwards and might be stuck with the thermacole or plywood mount/firewall that you are using. check if the motor can rotate freely by hand.

Title: Re: Avionic 1818 micro brushless motor Post by: mks on March 29, 2014, 10:19:48 PM I looked into it through air vent with a lense and torch.. it showed a broken wire inside.
I have opened it up for rewinding.. the copperwire they have used for the winding is of very poor quality.. |
