介绍了一种变磁链内置式永磁同步电动机。通过在转子磁屏障中采用可移动的磁通缩短铁件，可以在一定程度上减小永磁体的磁链。在弱磁控制区域，由于永磁体磁链的减小，削弱电枢磁链所需的d轴电流变小。与传统的IPMSM相比，在逆变器供电能力相同的限制下，所提出的IPMSM的恒定输出功率工作范围可以被扩展。d轴电流变小也有助于提高效率以及功率因数特性，特别是在轻负载、高速操作时。通过选择合适的可动铁件插入方案，可以实现所提出的IPMSM的最佳运行性能。通过实验验证了本文提出的IPMSM的优点。
An interior permanent magnet synchronous motor (IPMSM) with variable permanent magnet flux linkage is introduced in this paper. By adapting movable flux-shortening iron pieces in the flux barriers of the rotor, it is possible to decrease the permanent magnet flux linkage to some extent. In the flux-weakening control region, the required d-axis current to weaken the armature flux linkage becomes smaller due to the decrease of the permanent magnet flux linkage. The constant output power operating range of the proposed IPMSM can be extended compared to the conventional IPMSM under the same limitation of the supply ability of the inverter. The becoming smaller d-axis current also contributes to the improvement of the efficiency as well as the power factor characteristics especially at light load, high speed operation. By choosing suitable inserting scheme of the movable iron pieces, it is possible to realize optimal operating performance for the proposed IPMSM. The advantages of the IPMSM proposed in this paper are verified with experiments.
