The invention discloses a force feedback type closed-loop control underwater propeller, and the propeller comprises a shell; a controller and a brushless direct current motor are arranged in the shell, a transmission shaft of the brushless direct current motor penetrates out of one end of the shell to be used for fixing a propeller located on the outer side of the shell, and a flow guide cover is installed outside blades of the propeller; a Hall position sensor is mounted at a rotor of the brushless direct current motor; a thrust sensor is fixed to the shell, the thrust sensor and the Hall position sensor are both in communication connection with the controller, and after receiving a thrust control signal, the controller drives the brushless direct current motor to drive the transmission shaft to rotate and further drives the propeller to rotate to generate thrust. The force feedback type closed-loop control underwater propeller has the advantages of being accurate in thrust output, self-adaptive, resistant to interference, small in dependence on the whole, sensitive in response, reliable in work and the like, the adaptability to maritime work equipment such as various UUVs, ROVs, ships, drilling platforms and the like is good, and the integration and control difficulty with the control whole is reduced.
