摘　　要：基于具体工况下的起重机运行条件,运用永磁同步电机设计理论,设计出适合起重机低转速大转矩运行特性的永磁同步电机。利用Ansoft/Maxwell中RMxprt模块建立电机有限元模型,并基于二维瞬态电磁场对所建模型进行仿真研究,计算得到电磁转矩变化曲线和电感参数,不仅为起重机用永磁同步电机的结构优化提供方案,还为进一步研究低转速大转矩条件下永磁同步电机的控制策略提供理论基础。A permanent magnet synchronous motor suitable for crane at low speed and high torque is designed following the design theory of permanent magnet synchronous motor based on crane operations under specific conditions. Finite element model of the motor is established by using RMxprt module in Ansoft/Maxwell, and the model is simulated based on two- dimensional transient electromagnetic field, resulting in electromagnetic torque changing curve and inductance parameter. The research not only provides a structural optimization scheme for permanent magnet synchronous motor but also lays theoretical foundation for further research on control strategy of its operation at low speed and high torque.
