Details
• Specifically designed for small and medium-sized ROV propulsion equipment, its propeller blades are symmetrical with balanced forward and reverse thrust.
• Equipped with a closed-loop speed control function, which is a major highlight of this product.
• When multiple devices are used simultaneously, this function ensures that the speed accuracy of each device reaches ±10rpm, meeting the requirement of high consistency.
