采用有限元方法对内磁体无刷直流电动机（BLDC）的dq模型进行了轴链和跨轴链的非线性分析。该模型用于比较传统形式的无刷直流电机与具有q轴磁阻的新型无刷直流电机的竞争设计。结果表明，磁通屏障电机将提供(i)相同的额定性能，（ii）更好的过额定性能。
Finite element analysis is used to obtain the non-linear variation of axis and cross-axis flux-linkages for a dq model of an interior magnet, brushless DC motor (BLDC). The model is used to compare competing designs of the conventional form of BLDC with designs of a novel type that has q-axis flux barriers. It is shown that the flux-barrier motor will give (i) equal rated performance, and (ii) better over-rating performance.
