Good Evening Folks
I have a bit if an odd situation here. I am sure it is something I have (or have not) done, but damn if I know what it is. This is kind of a continuation of another thread I recently posted, but the problem is more specific, so I have started a new thread.
I have an older ZMR 250 with a Naze32 rev 6a, Rotorgeeks RG20 ESC’s and Cobra 2204 2300 motors. I started having some problems with the # 3 motor and I initially thought it was the ESC because of some of its behavior. Then I noticed an “odd” sound when I turned the motor over by hand, so I opened it up. Three of the magnets had come unglued and dropped and two more were broken in half. I tried to repair it (glue the magnets back in) which I have done in the past with complete success. This time however, the motor had noticeably less power than the other three. I had a spare so I replaced the motor. Now here is the weird part……To control rotation back when I built this machine I crossed the leads on two of the motors…..numbers 2 & 3 so they rotated counter clockwise (CCW). Now I would probably just handle that in BLheli, but I didn’t do this one that way. So I put the new replacement in, crossed the leads and lit it off……..it rotated in the wrong direction (CW). Keep in mind I have not even plugged the machine into the BLheli configurator so there is no chance the rotation got switched there. I did upgrade the firmware on the Naze32, but it operated correctly after I did that before I replaced the motor. Ok….so just out of idle curiosity, I changed the leads on #3 so they were not crossed. Any idea what happened? Yep, I now have CCW rotation on #3. So the bottom line is that I have three motors with the leads NOT crossed and one motor with the leads crossed and all motors rotate in the correct direction
As I said, I suspect it’s something stupid I have, or have not done and if anyone could point me in that direction I would be grateful!! Thanks!
