摘  要：高速旋转的电机在运动过程中产生的动平衡，在许用范围内对电机不会造成影响。通过质心平移法将整个电机质心处的许用不平衡量通过力学计算平移到易处理的转子两个端面进行校正，从而对电机的振动进行有效调节。

Abstract: Dynamic balance generated by high-speed motor has an effect on motor in the permitted scope.Permitted non-balance in  barycentre of motor will be moved to two end sides of the rotor to revise by  parallel movement of barycentre.  Consequently,vibration of the motor will be adjusted.
Key words: dynamic balance;barycentre;parallel movement;non-balance values.
