【摘要】 在变极蓄能电机中，ｄ轴与ｑ轴往往与磁极的极心和极间均不重合。本文提出，在采用双反应理论分析这种电机时，所用模型为一个单元电机，其极数为２ｐ，正弦分布和余弦分布的交极蓄能电机分别采用正弦型和余弦型模型时，在不计饱和影响的条件下，用气隙磁导的观点可以证明ｄ轴与ｑ轴之间没有耦合关系：进而对两种模型导出采用双反应理论进行分析的有关公式，及决定主波磁密的气隙导磁系数表达式。更多还原

【Abstract】 The d-q axes of polc-changing pumped stomge machines are usually alignedwith neither the central line of the pole nor the central line of the inter-pole regions. Amachine model with 2p poles is used to analyze such kind of machines using two reac-tion theory. Two typca of niachine models with their poles distributed sinusoidally andcosinusoidally are used respectively for the sine and cosine-distribution pole-changingpuniped storage machines. It is certified that, in view of the air gap permeance, there isno coupling between d and q axes if the saturation effects are not accounted.Furthermore, this modified d-q axes theory is applied in the analysis of thepole-changing pumped stomge machines, and the formulas for calculating the air gappenneance used for determining the main wave flux density are deduced.更多还原
