1747-SDN步进和伺服电机可以拆开检修或改装吗?
不要,好让厂家去做,拆开后没有专业设备很难安装回原样,电机的转定子间的间隙无法保证。磁钢材料的性能被破坏,甚至造成失磁,电机力矩大大下降。
14.伺服控制器能够感知外部负载的变化吗?
如遇到设定阻力时停止、返回或保持的推力跟进。
15.可以将国产的驱动器或电机和国外的电机或驱动器配用吗?
原则上是可以的,但要搞清楚电机的技术参数后才能配用,否则会大大降低应有的效果,甚至影响长期运行和寿命。好向供应商咨询后再决定。
16.使用大于额定电压值的直流电源电压驱动电机吗?
正常来说这不是问题,只要电机在所设定的速度和电流极限值内运行。因为电机速度与电机线电压成正比,因此选择某种电源电压不会引起过速,但可能发生驱动器等故障。
此外,保证电机符合驱动器的小电感系数要求,而且还要确保所设定的电流极限值小于或等于电机的额定电流。
事实上,如果你能在你设计的装置中让电机跑地比较慢的话 ( 低于额定电压 ) ,这是很好的。
以较低的电压 ( 因此比较低的速度 ) 运行会使得电刷运转反弹较少,而且电刷 / 换向器磨损较小,比较低的电流消耗和比较长的电机寿命。
另一方面,如果电机大小的限制和性能的要求需要额外的转矩及速度,过度驱动电机也是可以的,但会牺牲产品的使用寿命。
