Abstract

This paper proposed a precise tubular permanent magnet linear motor(PMLM) iron loss calculation model, in which the effect of the motor primary structure and harmonic were taken into account. The simulation model of the linear motor was built by finite element method. Base on the model, the no-load field map and each point of the magnetic density waveform changes were provided. Combination of finite element method and iron loss calculation model which proposed in this paper, the more accurate core loss of tubular PMLM was obtained and the influence of the speed on the stator core loss was discussed. The iron loss calculation model was verified by the measured data.
管状永磁直线电机一次铁损耗分析
提出了一种考虑电机一次结构和谐波影响的管状永磁直线电机铁损精确计算模型。采用有限元法建立了直线电机的仿真模型。在此基础上,给出了空载磁场图和各点磁密度波形变化。将有限元法与本文提出的铁芯损耗计算模型相结合,得到了更为精确的管状永磁转子铁芯损耗,并讨论了转速对定子铁芯损耗的影响。通过实测数据对铁损计算模型进行了验证。
