Abstract

The invention provides a multi-channel single-phase limited inclination angle direct drive motor and a rudder system. The motor comprises a stator and a rotor, the stator is connected with a cabin ofan aircraft and is provided with 2N winding grooves, the 2N winding grooves are uniformly arranged along the circumferential direction of the stator, and windings are arranged in the winding grooves.The stator comprises N uniformly distributed single-phase winding channels, and any one single-phase winding channel is formed by winding the windings in two adjacent winding grooves. The rotor is rotatably arranged in the stator and comprises a Halbach magnetic pole array layer and a rotor supporting assembly, the Halbach magnetic pole array layer sleeves the rotor supporting assembly and comprises a plurality of first circumferential magnetizing permanent magnets, and the number of poles of the first circumferential magnetizing permanent magnets is the same as the number of the winding grooves. The rotor is directly connected with a control surface assembly of the aircraft. By applying the technical scheme of the invention, the winding utilization rate and the motor torque density of thedirect-drive motor can be improved, and the output characteristic of the direct-drive motor is further improved.

Description

technical field [0001] The invention relates to the technical field of electric servo actuators, in particular to a multi-channel single-phase limited inclination direct drive motor and a rudder system. Background technique [0002] As an important part of the guidance and control system of aerospace vehicles, the rudder system undertakes the important task of aircraft attitude adjustment. It realizes the function of driving the deflection of the rudder surface by controlling the rotation direction and angle of the output shaft of the rudder, thereby changing the aerodynamic load on the aircraft and realizing rapid Attitude adjustment. According to the different forms of driving energy, the rudder system can be divided into three main types: electric, pneumatic and hydraulic. Due to the compact structural design requirements of aerospace vehicles, large-capacity high-voltage batteries are usually used as a unified energy supply, so the electric rudder system is the main for...
