I am doing some research on ROV motors and propellers. Full disclamer: I am a recent M.Sc. Mech. Eng. graduate, and a colleague and I designed and sell a [ dynamometer]. The beta units are available since the end of August.
I’d like to know a few things…
- How important is range and power for ROVs? Is there any use in improving efficiency of the prop/motor? Is overheating a problem?
- A lot of hobbyist for quads are building thrust test rigs. Have you seen any of that before for ROV?
- How well are underwater props characterized? If you know the relative waterspeed and rpm of the prop, is the torque information available? With the RPM and torque, it is possible to find the optimal motor for the task.
I know quite a lot about motor testing, and I will be available to answer questions here.
