Dismantling a 1930 - RC-Monster Forums

Hayden · 02:10 AM

Before I dismantle my 1930 is there warranty on these things? It came with basically no specification on the motor.
What happened I was running it on my test bench with a medium APC propeller and after 1min of running and stopping…etc (testing it) it smoked the battery was cold and the speed control was not even warm practically room temperature did the motor fail? or was there too much load?:026:

I’m eager to pull it apart. how do you get it apart? do you mount it on a board and twist the motor can? So the can comes away off the purple front mounting plate.
OR do you desolder the end plate?

and the esc was a mgm 12012 runing a flight power 4cell lipo

Well...Your problem was probably the fact that there was NO load...If a brushless motor is run for more than a few seconds without a load...It's not good for the motor...Obviously...

It had about the same or a bit more load than in my touring car that I ran for half an hour at a time. I ran the r/c car no load for a ling time taking rpm measurement tests that was fine, I tried it on a smaller prop for 3min or so twice and that was fine I think it had plenty of load it started to move the bench….I don’t know what are your thoughts guys?

A smoking motor is not good at all! (isolation from the copper is melting)

You are sure it's the motor? you can test the motor first by shortening two of the three wires in random order and see if there is some kind of resistance when turning the shaft (mechanical resistance i mean). Shorten all three of them to see of the resistance has become bigger and more consistent.

You dismantle the motor by getting the purple mounting plate stuck and turning the motor-body. I heard it's quite difficult to do. The aluminum body is so thin, that you can't put use pressure from two sides. You need to clamp it all around.
