摘　　要：文中首先从理论上分析直驱型永磁电机的齿槽转矩数学模型,讨论影响电机齿槽转矩的主要因素和降低永磁电机齿槽转矩的关键参数设计方法,分析直驱型潮流能发电机组加工运行过程中容易出现的影响电机齿槽转矩的主要原因。最后采用有限元仿真方法,结合样机实验测试,对永磁电机齿槽转矩进行对比分析。样机及仿真分析结果表明,直驱型潮流能发电机的启动转矩主要受电机电磁方案设计、样机加工误差及运行环境等因素影响。This paper analyzes the mathematical model and main factors of cogging torque in the direct-drive permanent magnet generator（PM generator） on the theoretical basis. The key parameter design method has been discussed to reduce the cogging torque of PM generator, and the main reasons influencing cogging torque are summarized focusing on the fabricating and operating process. The finite element simulation method combined with prototype experimental values are presented to conduct comparative analysis on the cogging torque and validate the theoretical analysis results, which indicates that electromagnetic design, machining error and operating environment affect the started-torque of generator in the direct-drive tidal current power system.
