4, 2 相和 5 相步进电机有何区别,如何选择?
2 相电机成本低,但在低速时的震动较大,高速时的力矩下降快。 5 相电机则振动较小,高速性能好,比 2 相电机的速度高 30~50% ,可在部分场合取代伺服电机。
5, 何时选用直流伺服系统,它和交流伺服有何区别?
直流伺服电机分为有刷和无刷电机。
有刷电机成本低,结构简单,启动转矩大,调速范围宽,控制容易,需要维护,但维护方便(换碳刷),产生电磁干扰,对环境有要求。因此它可以用于对成本敏感的普通工业和民用场合。
无刷电机体积小,重量轻,出力大,响应快,速度高,惯量小,转动平滑,力矩稳定。控制复杂,容易实现智能化,其电子换相方式灵活,可以方波换相或正弦波换相。电机免维护,效率很高,运行温度低,电磁辐射很小,长寿命,可用于各种环境。

3、零部件松动
在安装时由于个别零部件的松动(如轴承预紧机构,轴系定位机构等),导致系统定位不准,非正常位置啮合,轴系移动,产生振动和噪声。这一系列需从设计结构出发,尽量保证各机构的联接稳定,采用多种联接方式。
4、传动部件损坏
在安装时由于不当操作损伤传动部件,导致系统运动不准确或运动失稳;高速运动部件由于受损导致油膜振动;人为造成运动件动不平衡;都产生振动和噪声。这些原因在安装过程中都是必须注意和尽量避免的。对无法修复的损伤零部件,必须予以更换,以保证系统获得稳定的噪声等级。
减速机噪音大的解决办法之二:使用与维护
减速机的正确使用维护虽不能降低系统噪声等级,保证传递精度,但却能防止其指标劣化,增大使用寿命。
1、内部清洁
减速机内部零件的清洁是保证其正常运转的基本条件,任何杂质污物的进入都将影响并损伤传动系统,导致噪声的产生。
2、工作温度
保证减速机正常的工作温度,避免零部件因过大的温升产生变形,确保齿轮正常啮合,从而防止噪声的增大。
3、及时的润滑和正确使用油品
