Abstract: A ducted fan device integrated with a permanent magnet synchronous disc flat wire motor for a flying copter car, including a rotor system, a stator system, an air intake/exhaust control system, a detection system, a driving system and a power supply system. The stator system includes a motor shell, and flat wire coils respectively arranged on an upper end face and a lower end face of an inner wall of the motor shell are connected in series. The rotor system is arranged inside the stator system, including axial flow and radial flow composite integrated blades and permanent magnets. A part of centrifugal blades are replaced by the permanent magnets which are located on an outer side.
