It seems we’ve encountered an issue with the T100’s. We were doing some more in depth testing as we near the end of our project. We were trying to make the ROV neutrally buoyant, and also testing maneuverability and stability in a small tank.
While testing, we suddenly noticed one of the motors was not running. Upon further inspection, when powering the motor, both in and out of water, it fails to make a full rotation. It turns a little, but it’s inconsistent- sometimes it fails to engage at all. The prop jitters a little and there’s a high pitched beeping to accompany it.
We searched for shorts and any flaw in the wiring, and found nothing. We also tested the ESC with another motor and it worked fine. The individual motor, which seems to be the trouble, worked fine before this point.
We decided to do some more inspection, and followed the disassembly procedure to take apart the motor. I’ve attached some pictures for your review. We’re stumped, there isn’t any visible problem or issue.
Any help would be greatly appreciated.
