| 摘 要： | 针对无轴承电机悬浮控制系统模型中,两套绕组轴线坐标角度与模型刚度的确定均建立在一系列假设条件下,使实际数值与理论数值之间存在较大误差,且目前尚无对两套绕组轴线坐标关系及控制系统模型系数的精确测定方法,根据感应型无轴承电机气隙磁场的固有特性,建立了含两套绕组轴线坐标关系与转子偏心的磁悬浮力数学模型,提出了直接测定两套绕组轴线坐标关系及悬浮力模型系数的实验方法,精确测定出两套绕组坐标关系及控制系统的模型系数,可使无轴承电机实现精确控制.

| Abstract: | The axis angle between the two windings and the coefficients of the levitation control system are both based on a series of hypothesis in a bearingless motor,which makes a significant difference between the theoretical calculating values and the practical values.At present there is still no precise method to obtain the axis angle and the coefficients.According to the natural characteristic of the air-gap magnetic field in an induction type bearingless motor,a model of the magnetic levitation force was estab... |
