The invention discloses an electric drive type outer stator coil turbine ducted engine and an aircraft, and relates to the technical field of aviation parts, the electric drive type outer stator coil turbine ducted engine comprises a turbine duct and at least one duct driving unit, each duct driving unit comprises a turbine fan and a brushless driving mechanism, and the traditional turbine ducted fan is connected with the brushless driving mechanism. A driving motor is mounted on a central shaft at the rear end of a fan in a turbine duct, and the motor mounted inside cannot block duct airflow, so that the radius of the motor cannot be too large, the overall torque output by the motor is small, larger current must be introduced into the motor, the current heat loss of the motor is high, and the running efficiency is low; the stator coil and the rotor permanent magnet are located in the peripheral area of the fan, the relative linear speed between the stator coil and the rotor permanent magnet and the overall efficiency of the motor are higher, and under the condition that the maximum current cannot be further increased and the peak value is kept unchanged, when the forward injection voltage is higher, the motor can input electric energy, and the conversion power for outputting mechanical energy is larger.
本发明公开一种电驱动型外定子线圈涡轮涵道发动机及飞行器,涉及航空部件技术领域,包括涡轮涵道和至少一个涵道驱动单元,单个所述涵道驱动单元包括涡轮风扇和无刷驱动机构,传统的涡轮涵道风扇,其驱动电机安装在涡轮涵道中的风扇后端中心轴上,由于内部安装的电机不能阻挡涵道气流,导致电机半径不能太大,以致电机输出的整体转矩偏小,电机就必须要通入更大的电流,造成电机电流热损高、运转效率较低,本发明中定子线圈和转子永磁位于风扇的外围区域,它们之间的相对线速度,电机整体效率也更高,在最大电流不能进一步升高、保持峰值不变的情况下,正向注入电压越高时,电机可以输入电能、并输出机械能的转换功率就更大。
