摘要
由于加工或装配误差等原因,电主轴转子存在着一定的偏心量,这个偏心量影响电主轴系统的机电耦合特性。本文基于绕组函数法,计算电主轴在转子静态偏心状态下的电感参数,在此基础上建立高速电主轴转子存在静态偏心量时的机电耦合动力学数学模型,并对电主轴启动过程进行仿真分析。分析结果表明:转子静态偏心量的存在会使电主轴起动时间增长,电主轴进入额定状态后转子仍然存在较大的电流。该结论为进一步研究高速电主轴系统的机电耦合动力学特性提供理论基础。
Some eccentricity always exists in the rotor in high speed motorized spindle because of processing or assembling error.The eccentricity can affect the electromechanical coupling characteristics of high motorized spindle system.Inductance parameters of the high speed motorized spindle in the condition of eccentric are calculated based on the method of winding function.On the basis of this,the electromechanical coupling mathematical model of the high speed motorized spindle in the condition of eccentric are developed and simulated.It is shown that the existence of the static eccentricity in the rotor delay the starting of the high speed motorized spindle.The mathematical model provides the theoretical basis for further research on the electromechanical coupled dynamical performance of high speed motorized spindle system.
