Document Type and Number:
WIPO Patent Application WO/2009/143669
Kind Code:
A1
Abstract:
A power driving system for an aircraft includes at least two external rotor brushless motors (110,120), each of which has a stator (112) and a rotor (114). Said stator is provided with a through hole (112a), through which said stator can be arranged on the main shaft of the aircraft. The rotor is arranged around the outer periphery of the stator. The rotor wings (103,104) of the aircraft are driven to rotate by the rotor of the motor, and the main shaft is not rotated. Compared with the conventional power driving system, present driving system has simpler structure and lower cost and can decrease pollution.
