The invention discloses an integrated thruster for contra-rotating propellers. The integrated thruster for the integrated contra-rotating propellers mainly comprises a guide pipe, the propellers, a permanent magnetic synchronous motor and thrust bearings. The pair of contra-rotating propellers are integrally installed with motor outer rotors and are directly driven by excitation of armatures of the permanent magnetic synchronous motor arranged in a sealing cavity, and thrust generated by the propellers is transmitted by the water lubricating thrust bearings. The armatures of the motor are installed and positioned through a middle connecting piece and is installed in the sealing cavity after being sleeved with a stainless steel protection sleeve. The whole sealing cavity is filled with pressure compensation liquid and stretches out to a connecting piece on the outer side of the guide pipe from the interior of a support together with a wire through a through hole. The integrated thruster for the integrated contra-rotating propellers is simple in structure, high in integration, easy to install and maintain and capable of achieving high efficiency and low noise of a propelling system under the water or on the water surface, and can be matched with an external pressure compensator to serve as a thrust source to work in the whole-sea-depth range.
