In particular, approximate expressions for the air gap flux and the airgap flux density are derived. 特别是,近似表达式气隙磁通和气隙磁通密度的计算公式。
Considering the inconvenience of using the magnetic vector potential as state variable, magnetic flux density is used as the state variable in the design optimization. 针对以往用磁位作为状态变量不方便的情况,文中直接采用磁通密度为状态变量。
