MOTOR DRIVEN PROPULSOR OF AN AIRCRAFT
DRIVE
November 1, 2023
A motor driven propulsor (200) of an aircraft (10) includes magnets (402) disposed in fan shrouds (724) of fan blades (208) connected with a fan hub (208), a stator (218) having individual conductive coils (400) in a nacelle (702)located radially outside of the fan hub (208), and a distributed inverter assembly (500) having several inverter power stages (404) and gate drivers (504), each of the inverter power stages (404) coupled with a separate gate driver (504) of the gate drivers (504) and a separate coil (400) of the coils (400) in the stator (218). Each of the gate drivers (504) is configured to individually control supply of direct current to the corresponding inverter power stage (404). Each of the inverter power stages (404) is configured to convert the direct current supplied to the inverter power stage (404) to an alternating current that is supplied to the corresponding coil (400) in the stator (218) to rotate the magnets (402) and the fan blades (208) around a center line (226) of the fan hub (208) for propelling the aircraft (10).
