开关磁阻电机(SRM)只由定子和转子铁心以及绕组组成。因此，它们具有简单而坚固的结构，并且成本低。然而，开关磁阻电机的转矩密度和效率普遍低于永磁同步电机。提出了一种新型的横向磁通型开关磁阻电机。所提出的TFSRM在转子铁心中加入永磁体，以施加反向偏置磁场，从而扩大了电机的工作范围，提高了转矩和效率。通过三维有限元分析和样机试验，验证了该方法的有效性和实用性。
Switched reluctance motors (SRMs) consist of only stator and rotor cores, and windings. Thus, they have a simple and robust structure, and low cost. However, torque density and efficiency of SRMs are generally inferior to those of permanent magnet synchronous motors (PMSMs). This paper presents a novel transverse-flux-type switched reluctance motor (TFSRM). The proposed TFSRM has permanent magnets in the rotor cores for applying reverse bias magnetic field, which can expand the operating area and improve both torque and efficiency. The validity and usefulness of the proposed TFSRM are proved by a three-dimensional finite element method (3D-FEM) and prototype tests.
