1. A ducted fan device integrated with a permanent magnet synchronous disc flat wire motor, comprising:
a rotor system,
a stator system,
an air intake/exhaust control system,
a detection system,
a driving system, and
a power supply system;
wherein the stator system comprises flat wire coils (4), a motor shell (5) having an annular barrel structure, and a stator conical shaft (6), wherein a plurality of layers of flat wire coils (4) are respectively arranged on an upper end face and a lower end face of an inner wall of the motor shell (5), the flat wire coils (4) on each of the end faces being connected in series in an end-to-end mode, wherein the stator conical shaft (6) is fixedly connected with a bottom of the motor shell (5) through a plurality of fixed pieces;
wherein the rotor system is arranged inside the stator system and comprises axial flow and radial flow composite integrated blades (1), a conical connecting sleeve (2), and permanent magnets (3), the conical connecting sleeve (2) being matched with the stator conical shaft (6), wherein the axial flow and radial flow composite integrated blades (1) are distributed in a circumferential direction of an outer side face of the conical connecting sleeve (2), and wherein the permanent magnets (3) are arranged on outer sides of the axial flow and radial flow composite integrated blades (1) and are located between an upper set and a lower set of the plurality of layers of flat wire coils (4); and
wherein the detection system is electrically connected with the motor shell (5) and the power supply system, the driving system is electrically connected with the flat wire coils (4) and the power supply system, and the detection system is electrically connected with the driving system.
