而一般来讲，大多数的风机转子都是属于刚性转子，通常在低速平衡就能达到和保证风机转子的使用精度要求。
Generally speaking, most of the wind turbine rotor is a rigid rotor, usually at low speed balance can be achieved and ensure the accuracy of the use of wind turbine rotor.
自驱动是对平衡精度影响最小的拖动方式，平衡精度可达最高，但只有结构允许的特殊转子才能使用这种拖动方式。
Self drive is the smallest impact on the balance of the drag mode, the balance of the highest accuracy, but only the structure allows the use of special rotor can be used in this way.
有源磁力轴承在高转速场合应用时，由于转子的不平衡响应，降低了转子的旋转精度。
The unbalance of rotor deteriorates the rotors rotating precision when active magnetic bearings are used in high speed condition.
