本文从永磁和直流励磁的位置、永磁和直流励磁磁场的串联/并联以及2D/3D磁场的角度对各种混合励磁电机进行了综述。分析了每类方法的优缺点。由于在HE电机中引入了额外的控制度，即直流励磁，因此弱磁控制策略更加复杂。比较了不同控制策略下的弱磁性能和效率。然后，通过控制励磁，强调了在高速运行时减轻不受控制的过电压故障风险的潜力。由于与纯永磁励磁相比，HE电机通常需要额外的直流线圈，因此空间冲突不可避免地导致电磁性能降低。最后，介绍了将励磁绕组和电枢绕组集成在一起的开路驱动电路技术，并总结了新型无直流线圈HE电机。
This paper reviews various hybrid excited (HE) machines from the perspective of location of PM and DC excitation, series/parallel connection of PM and DC excited magnetic fields, and 2D/3D magnetic fields, respectively. The advantages as well as drawbacks of each category are analyzed. Since an additional control degree, i.e. DC excitation, is introduced in the HE machine, the flux weakening control strategies are more complex. The flux weakening performance as well as efficiency are compared with different control strategies. Then, the potential to mitigate the risk of uncontrolled overvoltage fault at high speed operation is highlighted by controlling the field excitation. Since additional DC coils are usually required for HE machines compared with pure PM excitation, the spatial confliction inevitably results in electromagnetic performance reduction. Finally, the technique to integrate the field and armature windings with open-winding drive circuit is introduced, and novel HE machines without a DC coil are summarized.
