1、步进电机在低速时增加转矩的方法
1)选择步距角小的步进电机 在低速时转矩随转子齿数增加而变大。选择步距角小的步进电机能获得高转矩。十几上HB型转子齿数如为50齿,永久磁铁的漏磁将增加,但步会成比例,此结论在100齿以下均有效。三相HB型步进电机从1.2 (转子50齿)改变0.6 (转子100齿)。约增加1.4至1.8倍的低速转矩。
2)双极型接线
3)效率能盖上2倍。市场上很容易买到两相单极型或双极型步进电机,但双极型的驱动功率管比单极型的多。

近年来,在外墙装饰领域,仿石涂料的发展可谓如日中天,由于其节能环保、仿石效果逼真且成本相对石材更便宜的特性,得到非常广泛的应用。然而在具体施工的时候,由于具体操作不当或者产品质量问题,经常会出现各种涂装弊病。喷涂掉砂任何喷涂都会有损耗发生,喷涂中的掉砂属于正常现象,但可以通过施工控制在适当范围内。碎石级配不当、施工操作不当、涂料稠度不当容易造成喷涂掉砂现象发生。解决方法根据施工产品粘度,施工空气压力,施工人员手法等来判定,建议在工程开工前做涂布率测试。

仔细清洁在使用钢丝刷或者特殊化合物对挤出机机筒进行清洁前,应该将所有的高温熔体压力传感器都拆卸下来。因为这两种清洁方式都可能会造成高温熔体压力传感器的震动膜受损。当机筒被加热时,也应该将高温熔体压力传感器拆卸下来并使用不会产生磨损的软布来擦拭其顶部,同时高温熔体压力传感器的孔洞也需要用清洁的钻孔机和导套清理干净。保持干燥尽管高温熔体压力传感器的电路设计能够经受苛刻的挤出加工环境,但是多数高温熔体压力传感器也不能防水,在潮湿的环境下也不利于正常运行。
