We have a big problem with a ROV build we are testing.
The ROV have performed good, but after testing today we have had problems with several ESC’s litterally burning up! Have replaced the ESC’s but when retrying the ESC have shortcutted again. It even have effected other ESC’s. Now also 3 out of 12 thrusters wont work even on a new thruster and motorcontroller.
We had a similar problem earlier and found the problem to be related to a thruster issue where there where cracks in the stator on the thruster. It seems that there is shortages in the thruster that affects the system. After inspecting the thrusters we have now I can see several dings in the stator where it is some corrosion so my guess is that this might be the same issue as earlier.
Are there anyone out there that have had similar experiences?
