分段转子开关磁阻电机已被证明产生比常规开关磁阻电机显著更多的扭矩，因为每个线圈能够链接更多的磁通量。在以前的工作中，研究的拓扑结构的范围相对有限;没有考虑定子齿和转子段数选项的范围，并且设计没有以任何方式进行正式优化。本文旨在解决这一问题：使用有限元工具集进行优化，它描述了由此产生的机器，独特的转子部分比定子齿的数量更多。本文评估了可靠的齿和段选项，每个选项都进行了优化，以最大限度地提高扭矩能力。从评估中得出结论，根据扭矩产生和损失等标准对比每台机器的性能。为了验证这一优化过程，建立了一个原型机，并将其性能与这些预测进行了比较。
Segmental rotor switched reluctance machines have been demonstrated to produce significantly more torque than conventional switched reluctance machines because each coil is able to link more magnetic flux. In previous work, the range of topologies studied has been relatively restricted; there has been no consideration of the range of stator tooth and rotor segment number options, and the designs have not been formally optimized in any way. This paper seeks to address this: Using finite-element toolsets for optimization, it describes the resulting machines-uniquely featuring a greater number of rotor segments than stator teeth. This paper assesses the credible tooth and segment options, with each option optimized to maximize torque capability. From this assessment, conclusions are drawn, which contrast each machine's performance based on criteria including torque production and loss. In order to validate this optimization process, a prototype machine is built, and its performance is compared with these predictions.
