In this paper, the reluctance torque is utilized for improving the starting and average torques of a conventional brushless wound field synchronous machine (BL-WFSM). The conventional BL-WFSMs have an inherent issue of zero-starting torque. The existing BL topologies use expensive rare-earth permanent magnets (RE-PMs) to improve the starting torque; however, the marker price of RE-PMs fluctuates. Therefore, this paper proposes the use of the reluctance torque for improving the starting and average torques of BL-WFSMs. The winding topology and machine layout are adopted, from recently published work. The suggested approach increases the reluctance effect in BL-WFSM by optimizing the rotor shape. The reluctance effect is optimized, to improve the starting and average torques. The Kriging method and a genetic algorithm are used for the rotor optimization. A two-dimensional finite element analysis confirms the improved starting and average torques based on the increase in the reluctance torque.

在本文中，磁阻转矩用于提高常规无刷绕线励磁同步电机（BL-WFSM）的启动转矩和平均转矩。常规的BL-WFSM具有固有的零启动转矩问题。现有的BL拓扑结构使用昂贵的稀土永磁体（RE-PM）来提高启动转矩。然而，可再生能源的标价波动。因此，本文提出使用磁阻转矩来改善BL-WFSM的启动转矩和平均转矩。根据最近发表的工作，采用了绕组拓扑和机器布局。建议的方法通过优化转子形状来提高BL-WFSM中的磁阻效应。磁阻效应得到优化，以提高启动转矩和平均转矩。Kriging方法和遗传算法用于转子优化。二维有限元分析基于磁阻转矩的增加确认了起动转矩和平均转矩的改善。
