转子节距
Variable pitch vertical axis turbines have been proposed, which can markedly increase the power extraction efficiency at low tip speed through controlling the rotor blades pitch at all points of their rotation cycle.
目前已经提出了一种变螺距垂直轴水轮机,它可以通过控制转子在一个旋转周期上所有点的叶片间距来显著提高能量的提取效率。
This paper presents the calculating method for stator and rotor harmonics unit leakage permeance, slot end and slot bottom pitch leakage reactance coefficient, starting torque, breakdown torque, and starting current in designing of motors with further pole ratio.
阐述远极比电机设计时定、转子谐波单位漏磁导、槽口、槽底节距漏抗系数、起动转矩、最大转矩、起动电流的计算方法。
