Abstract

The invention relates to a DC motor, in particular to a shipping propulsion DC motor. The shipping propulsion DC motor comprises a left end cover arranged at the left end of a stand and a right end cover arranged at the right end of the stand according to the technical scheme provided by the invention. The left end of a main shaft is arranged on the left end cover by utilizing a first bearing; the right end of the main shaft is arranged on the right end cover by utilizing a second bearing; in addition, the right end of the main shaft extends out of the right end cover to form a drive end; a rotor is arranged on one section of the main shaft located on the stand, the inner wall of the stand is provided with a stator at a position corresponding to the rotor, and the stator surrounds the periphery of the rotor. The shipping propulsion DC motor is characterized in that the left end of the main shaft is connected with a pressure plate; an annular angle loop is arranged between the left side of an inner loop of the first bearing and the pressure plate; a bearing inner cover fixed on the inner wall of the left end cover is arranged at the right side of the first bearing; and the centre of the bearing inner cover is provided with a shaft hole. The DC motor can solve the dynamic problem of electric propulsion of domestic small-scale work boats.

Description

technical field [0001] The invention relates to a DC motor, in particular to a ship propulsion DC motor. It is mainly used to drive the ship's main propeller, bow thruster, fire pump and other equipment. technical background [0002] At present, domestic small and medium-sized operation ships are all propelled by diesel engines, which generally have problems such as high energy consumption, poor maneuverability, and heavy weight. With the advancement of modern power electronics technology, electric propulsion of ships is an inevitable result. Electric propulsion has been widely used in foreign small workboats. The use of electric propulsion for ships has the advantages of good economy, good maneuverability, good safety, space saving, low noise, and low emissions. The economic benefits of ships using electric propulsion are obvious. With the improvement of power electronic devices, the development of motor control technology and harmonic suppression technology, and the ma...
