This paper presents the polyphase doubly salient stationary permanent magnets motors with no magnetic flux reversal in the stator core as well as splittable stator core. Due to its high power and torque densities as well as efficiency gains due to losses reduction in the iron and in the drive through unipolar converters, this motor becomes an attractive option for several applications including electric traction. In addition, it is a rugged brushless machine without windings or bars in rotor and permanent magnets housed in the stator reducing the risk of demagnetization by temperature. The strategy for the non-reversal of the magnetic flux in the stator core and its partition is explained and performance comparisons with same dimensions switched reluctance motors (SRM) are carried out through simulations and the results evaluated, observing better results for the doubly salient permanent magnets machine.

磁通反向自由可拆分定子铁芯双凸极永磁电机

本文介绍了在定子铁芯中没有磁通反转的多相双凸极固定永磁电机以及可拆分的定子铁芯。由于其高功率和扭矩密度以及通过单极转换器减少铁和驱动器中的损耗而带来的效率增益，该电机成为包括电力牵引在内的多种应用的有吸引力的选择。此外，它是一种坚固的无刷电机，转子中没有绕组或棒，定子中装有永磁体，可降低因温度而退磁的风险。解释了定子铁心及其分区中磁通量不反转的策略，并通过模拟和评估结果对相同尺寸的开关磁阻电机 (SRM) 进行了性能比较，
