Abstract

The invention discloses a permanent magnet transverse segmentation dislocation type brushless double-rotor motor based on a unilateral magnetic adjustment principle, which belongs to the field of underwater unmanned vehicle propulsion motors, and aims to solve the problems of serious winding heating and difficult heat dissipation of an existing contra-rotating motor for propulsion of an underwater unmanned vehicle. The motor comprises an annular winding stator, a permanent magnet rotor and a modulation rotor which are coaxially arranged from outside to inside in the radial direction. The permanent magnet rotor is arranged in a segmented staggered mode, and permanent magnet magnetic fields which are evenly distributed along the circumference and distributed in a segmented staggered mode in the axial direction are formed. The modulation rotor modulates a permanent magnet magnetic field which is uniformly distributed along the circumference and is distributed in a segmented and staggered manner along the axial direction into a stator winding magnetic field which is distributed along the axial direction, and electromagnetic torques borne by the permanent magnet rotor and the modulation rotor are equal in real-time magnitude and opposite in direction; an output shaft of the permanent magnet rotor is connected with a forward propeller of the contra-rotating propellers, and an output shaft of the modulation rotor is connected with a reverse propeller of the contra-rotating propellers.

Description

technical field [0001] The invention relates to a motor body structure and belongs to the field of propulsion motors for underwater unmanned vehicles. Background technique [0002] Marine equipment is an important equipment for underwater reconnaissance and surveillance, intelligence collection, and underwater operations. The innovative development of underwater unmanned aerial vehicles has great strategic and economic significance for my country's protection of maritime sovereignty and development of marine resources. [0003] The propulsion system of underwater unmanned vehicles generally includes two kinds of propellers: single propeller and counter-rotating propeller. Among them, compared with the single propeller, the counter-rotating propeller technology can not only overcome the shortage of the rolling moment generated when the single propeller rotates, but also absorb the rotational kinetic energy in the wake of the front propeller and reduce the energy loss of the s...
