Description
本發明是有關於一種推進器，特別是指一種水下推進器。The present invention relates to a propeller, and more particularly to an underwater propeller.
近年來遠端式無人載具(Remotely Operated Vehicle，ROV)及自主式無人載具(Autonomous Underwater Vehicle，AUV)隨著海底資源開發及科學研究的擴展，已逐漸發展成熟，並投入實際應用，這些的載具都需要至少一個推進器(thruster)來提供動力，一般而言，為了滿足海底作業的特殊環境需求，這些載具的推進器必須要滿足體積小、輸出扭力大、安靜、過載保護等需求特性。In recent years, Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) have gradually matured and put into practical use with the expansion of seabed resources development and scientific research.

No. 2002/0083880 A1 discloses a remote type water downloading device in which a rotor of a motor of the propeller has a plurality of blades, and the motor can drive the rotor to rotate the blades by magnetic force.

The problem of overloading and heating is not satisfied, and the demand characteristics of overload protection cannot be met.
