1756-PB72.选择步进电机还是伺服电机系统?
答:其实,选择什么样的电机应根据具体应用情况而定,各有其特点。
3.如何配用步进电机驱动器?
答:根据电机的电流,配用大于或等于此电流的驱动器。如果需要低振动或时,可配用细分型驱动器。对于大转矩电机,尽可能用高电压型驱动器,以获得良好的高速性能。
4. 2相和5相步进电机有何区别,如何选择?
答: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?
答: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。
交流伺服电机也是无刷电机,分为同步和异步电机,目前运动控制中一般都用同步电机,它的功率范围大,可以做到很大的功率。大惯量,高转动速度低,且随着功率增大而快速降低。因而适合做低速平稳运行的应用。
