ROV Brushless Outrunner 3 blade thruster propeller

thingiverse

This innovative thruster propeller is built by assembling its printed components. Its blades are vertically printed, minimizing cleanup tasks significantly. The motor utilized in this setup is a high-performance 750KV brushless outrunner, paired with a mounting kit for added stability. When powered at 75 Watts on a standard 12-volt system, the three-blade design produces approximately 12.5N of thrust, offering precise control and maneuverability through its careful operation at half speed. While a two-blade configuration yields more overall thrust, the three-blade design excels at lower and mid-range speeds with superior efficiency. The symmetrical blade structure allows for precise handling during turns, where opposite directional propellers can often cause difficulties. For customers seeking alternative options, a dual-blade propeller model is also available. Inspiration for this innovative thruster has been drawn from Ole Godø's groundbreaking designs featured on homebuiltrovs.com. Instructions: Prior to use, the ABS-printed blades are strengthened by applying a brush of acetone along the printed surface.
