An integrated electric propulsion unit includes a housing, an AC motor, a beta rod, a propeller, a governor, an inverter, and a controller. The AC motor is disposed within the housing and includes a plurality of bearings supported within the housing, a hollow motor shaft rotatably coupled to the housing through the plurality of bearings, a stator supported by the housing, and a rotor mounted to the hollow motor shaft. And the beta rod can axially translate in the hollow motor shaft. A thruster is mechanically coupled to the hollow motor shaft. The propeller includes propeller blades having an adjustable pitch angle depending on the axial position of the beta rod. The governor is configured to adjust the pitch angle of the propeller blades by actuating axial translation of the beta-rod. The inverter is disposed within the housing and connected to receive direct current power for conversion to alternating current power. A controller is disposed within the housing and is configured to control operation of the inverter and control a pitch angle of the propeller blades.

    一种集成电力推进单元,包括壳体、交流电机、β杆、推进器、调速器、逆变器和控制器。交流电机设置在壳体内,并且包括支撑在壳体内的多个轴承、通过多个轴承可旋转地联接到壳体的中空电机轴、由壳体支撑的定子以及安装到中空电机轴的转子。β杆可在中空电机轴内部轴向平移。推进器机械地联接到中空电机轴。推进器包括推进器叶片,该推进器叶片具有取决于β杆的轴向位置的可调节的螺距角。调速器配置为通过致动β杆的轴向平移来调节推进器叶片的螺距角。逆变器设置在壳体内,并且连接以接收直流电力而用于转换成交流电力。控制器设置在壳体内,并且配置为控制逆变器的操作和控制推进器叶片的螺距角。
