Details
· An auxiliary propulsion device specifically designed for small ROVs or AUVs with a diameter of 300mm or more.
· It features a unique design with symmetrical blades and equal forward and reverse thrust.
· Its closed-loop speed control function ensures the speed accuracy of each unit reaches ±10rpm when multiple units are operated simultaneously, thus meeting the requirements for high consistency.
