提出了一种新型嵌入永磁体的直线混合式励磁换向电机。该电机在一次电机中采用励磁绕组，从而提供了所需的磁通控制能力。该电机的创新之处在于设计了一种模块化的初级结构。因此，即使在各种励磁电流下，它也具有非常对称和正弦的反电动势和平滑的推力。此外，由于嵌入了PM，因此所提出的电机不会发生PM不可逆的退磁。用时步有限元方法分析了电机的磁场分布、反电势和推力等电磁特性，验证了理论分析的有效性。
This paper proposes a new linear hybrid excited flux reversal motor with inset permanent magnets (PMs). The proposed motor adopts the excitation windings in the primary, hence offering the desired flux control capability. The novelty of the proposed motor is to design a modular primary structure. Then, it has very symmetrical and sinusoidal back electromotive force (back-EMF) and smooth thrust even at various excitation currents. In addition, because of the inset PMs, the proposed motor is free from PM irreversible demagnetization. The electromagnetic performances of the proposed motor are analyzed using the time-stepping finite-element method, such as magnetic field distribution, back-EMF, and thrust, verifying the effectiveness of the theoretical analysis.
