Computation of Brush Short Circuit Coefficients of DC Machines for Extremely Low Speed Drives
Pages: 16-21,31
Year: Issue:  2
Journal: S&M Electric Machines

Keyword:  直流电机 电刷 短路系数;
Abstract: 直流电机电刷短路整流片引起电枢电阻和磁链减小,这对运行于零或极低速的电机影响尤为严重。提出了一种比较简便的计算短路系数平均值的方法,将电机参数适当解耦,建立参数化程度较高的数学模型,便于把计算公式化。给出了最常见的1对和2对电刷情况下的数据,可供直流电机电磁计算时使用。
