First lab tests

Here are some impressions of our lab tests at the Leibniz-Institute for Baltic Sea Research. Now our ROV Drive Prototype is finally in its element and working great!

The nozzle and the propeller were manufactured with a 3D printer and were hydrodynamically optimized in CFD analyses for the drive of ROVs. In addition, the nominal speed and torque of our BLDC motor were adapted to the propeller.

The drive is extremely quiet and powerful. Calibrations with the motor controller could be carried out in the test basin without any problems. This was followed by various thrust tests with different hardware and software configurations. First test results already showed a thrust of 20 kgf at 1700 W input.

In the following revisions we will further increase the power and expect a thrust of more than 30 kgf.
