摘　　要：作为一种新型的圆筒型直线电机,横向磁通圆筒型永磁直线电机与传统永磁直线电机相比,定子齿槽与电枢绕组空间上相互垂直,实现了电负荷与磁负荷的解耦,易于实现高力密度,在高推力密度领域具有广泛的应用前景。本文针对在变速往复周期运动模式下横向磁通圆筒型永磁直线电机的铜耗、定子铁心损耗以及动子侧永磁体内涡流损耗展开研究。首先,研究电机按正弦规律往复运动即推力正弦变化时的铜耗计算方法。其次,计算其在变速往复周期运动模式下的定子铁心损耗,为了验证计算方法的准确性,设计了铁心损耗测试方法,并对测试结果和计算结果进行了对比分析。最后,计算其在变速往复周期运动模式下的永磁体内涡流损耗。As a novel tubular linear motor, the merits of transverse flux tubular permanent magnet linear motor（TFTPMLM） different from other traditional linear motors are as follows： there is no competition between the space requirement of flux carrying core irons and the space occupied by armature windings. It can increase the force density due to the magnetic load and the electric load are decoupled. Transverse flux tubular PMLM seems to be suitable for some fields requiring high force density. This paper investigates the copper loss, stator core loss and eddy current loss in permanent magnet of the transverse flux tubular PMLM in a variable-speed reciprocating periodic motion mode. Firstly, it is proposed the copper loss calculation method considering the armature winding current amplitude as sine function changes. Secondly, it is proposed a method of calculating the variable speed reciprocating periodic motion of the stator core loss. In order to verify the accuracy of calculation, the core loss measurement is designed and the comparison results are analyzed. Finally, the paper calculates the eddy current loss in permanent magnet of the transverse flux tubular PMLM in the variable-speed reciprocating periodic motion.
