【摘要】 永磁双凸极电机运行时,可能会出现以下常见故障:三相绕组线或/和三相霍尔连接线的错误接线;霍尔信号自身的故障,即恒为高电平或低电平,其电平不随转子位置变化而变化。出现这些故障后,电机的电动运行将受何影响,以及如何迅速判断并排故成为重要的实际问题。文中针对12/8极转子斜槽式永磁双凸极电机,列举了电机常见的故障模式,继而分别对霍尔信号线及三相线接线故障、霍尔信号本身故障进行了详细的机理分析,得出结论,给出每一种故障出现后电机的工作情况,并通过故障模拟及工程实践验证了文中分析结论的正确性及实用性。更多还原

【Abstract】 In the operation of the doubly salient permanent magnet(DSPM) motor,some possible failures can occur,including the wrong connections of three armature windings,the wrong orders of three hall sensors,and the failures of hall sensor signals themselves,that is the hall sensor signal keeps the high level or the low level to be unchanged with the rotor position.Aimed at a 12/8-pole skewed-rotor DSPM motor,the above three kinds of common failures are analyzed.Finally,experimental results are given to verify the conclusions.更多还原
