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.

An air - gap - flux observer used for air - gap - flux - orient control of 12 - phase synchronous motor speed regulation system is obtained.

进一步推导得到了气隙磁链定向控制12相同步电动机调速系统的气隙 磁链观测器.

But WVF can only control the air - gap flux and can not adjust the torque.

调压调频控制只控制了电机的气隙磁通,而不能调节转矩.
