Title:
DUCTED FAN DEVICE INTEGRATED WITH PERMANENT MAGNET SYNCHRONOUS DISC-TYPE FLAT WIRE ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/126736
Kind Code:
A1
Abstract:
A ducted fan device integrated with a permanent magnet synchronous disc-type flat wire electric motor, comprising a rotor system, a stator system, an intake/exhaust control system, a detection system, a drive system and a power supply system. The stator system comprises an electric motor housing (5). Upper and lower end faces of an inner wall of the electric motor housing (5) are each provided with a flat wire coil (4), and the flat wire coils (4) on the end faces are connected in series. The rotor system is arranged inside the stator system, and the rotor system comprises axial and radial composite integrated blades (1) and permanent magnets (3). The permanent magnets (3) replace a portion of centrifugal fan blades and are located on the outside. The detection system is electrically connected to the electric motor housing (5) and the power supply system. The drive system is electrically connected to the flat wire coils (4) and the power supply system. The detection system is electrically connected to the drive system. The present device implements the suspension and high-speed rotation of the rotor system, omits a bearing mechanism, reduces weight, reduces mechanical wear and noise, prolongs the service life, and reduces costs.
