1动车组牵引电机常见故障
牵引电机是动车组行进过程中 … 等
问题比比皆是,这种故障会造成牵引电机的运行负载超出额定数值,也就是说,会 … 故障排查确认后更换故障牵引电机,故障牵引电机需由专业厂家进行返厂 … 可借助风速计对故障牵引电机和无故障电机的出风口风速分别进行测定 …”
大佬谈电机,如何选择步进电机的型号?手把手教学! “… 哦。
一、步进电机
步进电机又称为脉冲电机,基于最基本的 … 的时代趋势。
二、步进电机选型的步骤与方法
1、步 … 结构,完全不同于交流、直流电机,电机的输出功率是可变的。 … ,最好选择反应式或永磁电机。这些电机的“空起频率”都比较高 …”
大佬深入浅出谈电机,如何使步进电机效率最大化? “… 达到最大值,新型步进电机大多是这种形式的。
早期生产 … 为2
/ 0.7=2.9A(大约)的电机。这样才能使驱动器的效率最大化 … 可以并联使用的。
如果能将电机后盖打开,看一下里边的接线 …
