摘　　要：为了改善长次级永磁同步直线电机在物流仓储产业及相关物流运输、分拣等方面的应用中存在的耗费高的问题,提出了一种高可靠性且造价较低的铁氧体永磁同步直线电机。通过建立电机二维有限元模型,在稀土永磁同步电机优化设计的基础上,将稀土永磁体更改为铁氧体,并分析电机电磁性能。为了提高电机推力,分析了槽深及匝数对电机推力、推力波动及铜耗的影响。该电机可以应用于物流分拣、传输线等场合,可以提高系统和平台的效率,降低建设成本。In order to solve the problem of high cost in the application of long secondary permanent magnet syn-chronous linear motor in logistics storage industry and related logistics transportation and sorting,this paper proposes a ferrite permanent magnet synchronous linear motor with high reliability and low cost.Based on the optimization design of rare earth permanent magnet synchronous motor,the two-dimensional finite element model of the motor is established,and the rare earth permanent magnet is changed into ferrite,and the electromagnetic performance of the motor is analyzed.In order to improve the motor thrust,the influence of slot depth and turn number on the motor thrust,thrust fluctuation and copper consumption is analyzed in this paper.
