1·Install rotor on axle hub.
在车轴轮毂上安装转子。
2·The hub treatment with a circumferential groove was tested on the stator hub and compared with the casing treatment over the rotor tip for a single stage axial flow compressor.
在单级轴流压气机上，用周向槽式处理机匣在静子内径处进行轮毂处理，与转子尖部机匣处理作类比。
3·Rotor design is comprised of some factors such as hub configuration, blade number, rotor diameter, rotor solidity and airfoil which have effects on helicopter performances.
旋翼设计包括桨毂构型、旋翼桨叶片数、旋翼直径、旋翼实度、翼型剖面等一系列影响直升机性能的因素。
4·The blades and the hub together are called the rotor.
叶片和枢纽一起被称为转子。
5·The impeller is integrated into the external rotor motor so that the motor is equal to a wheel hub. So the motor can be cooled by the airflow efficiently to prolong life.
叶轮与外转子电机构成整体， 成为叶轮轮毂的驱动电机被气流高效地冷却，可以延长风机寿命。
6·Additionally, the larger the circumferential velocity component of hub leakage flow, the greater the deleterious effect of hub leakage upon the rotor flow.
另外，叶根泄漏流的周向速度分量越大，泄漏流对转子流场的不利影响也越大。
7·Preferably, the hub has a diameter of between 40% and 50% of the diameter of the rotor, measured at tips of the blades, and is solid so as to prevent air passing through the hub.
优选的，毂的直径为在叶尖处测量的转予直径的40%和50%之间，且是实心的以防止空气越过毂。
