摘要
针对高速运行时有铁心直线电机铁耗大、效率低的不足,提出一种动磁式无铁心永磁直线电机模型。采用专业电磁分析软件JMAG对无铁心直线电机电磁场进行了瞬态分析计算。以电磁推力及其波动为优化目标,分别计算了不同电磁参数对电磁推力及其波动的影响。利用瞬态分析进行电机优化设计,提高了电机设计的精度。
According to the large iron loss and low efficiency defect occurred in the core linear motor high speed situation.Proposed a motive permanent-magnet linear coreless motor model.Transient analysis and calculation was carried out for the electromagnetic field of coreless linear motor,which based on professional electromagnetic analysis software JMAG.Take electromagnetic thrust and its fluctuation as the optimization target.Various electromagnetic parameters which influence to the electromagnetic thrust and its fluctuation had been calculated.Using transient analysis method makes motor optimal design,improve the motor design precision.
