Realization and Analysis of High-speed Motor Rotor Dynamic Balance

为了减小高速电机转子运转时振动带来的危害,校正转子的不平衡量,本文通过运用DYJ-D80型平衡机电测箱和DR5Z型自驱动平衡机对F3-8101020风机转子在400~2400 r/min转速范围内进行动平衡实验,得出了此转子的第一、第二临界转速分别为800 r/min和1600 r/min,风机转子转速越高不平衡量越大且对平衡精度要求越高的规律,并对动平衡过程中影响平衡精度的因素作了分析。通过本次动平衡实验,结合当前高科技的发展,最后对动平衡技术在算法、测量方式、平衡精度方面提出了展望。

In order to reduce the vibration damage of high speed rotor during operation,and correct of the imbalance in the rotor,the F3- 8101020 fan rotor in 400- 2400 r / min speed conducted experiment of dynamic balancing using DYJ- D80 model test case and DR5 Z self- driven. It is concluded that the first and second critical speed of the rotor were 800 r / min and 1600 r / min,respectively. The fan rotor speed,the greater the amount of unbalance will be,and the higher the accuracy of the balance of the law. The factors affected the accuracy of balance in the process of dynamic balance were analyzed. Finally,with the current high- tech development,the realization of this dynamic balance,it is put forward the prospect in balancing technology in the algorithm,measurement,precision balanced.
