伺服电机的资料 1、交流伺服电机的工作原理 伺服电机内部的转子是永磁铁，驱动器控制的U/V/W三相电形成电磁场，转子在此磁场的作用下转动同时电机自带的编码器反馈信号给驱动器，驱动器根据反馈值与目标值进行比较，调整转子转动的角度,所以伺服电机的精度决定于编码器的精度（线数）。2、什么是伺服电机？有几种类型？工作特点是什么？ 答：伺服电动机又称执行电动机，在自动控制系统中用作执行元件，原理是把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。 3、问交流伺服电机和无刷直流伺服电机在功能上有什么区别？ 答：交流伺服要好一些，因为是正弦波控制，转矩脉动小。而直流伺服是梯形波，但直流伺服比较简单，便宜。 A、永磁交流伺服电动机的发展 20世纪80年代以来，随着集成电路、电力电子技术和交流可变速驱动技术的发展，永磁交流伺服驱动技术有了突出的发展，各国电气厂商相继推出各自的交流伺服电动机和伺服驱动器系列产品并不断完善和更新。交流伺服系统已成为当代高性能伺服系统的主要发展方向，使原来的直流伺服面临被淘汰的危机。90年代以后，世界各国已经商品化了的交流伺服系统是采用全数字控制的正弦波电动机伺服驱动，交流伺服驱动装置在传动领域的发展日新月异。 B、永磁交流伺服电动机同直流伺服电动机比较，主要优点有： ⑴无电刷和换向器，因此工作可靠，对维护和保养要求低。⑵定子绕组散热比较方便。 ⑶惯量小，易于提高系统的快速性。⑷适应于高速大力矩工作状态。⑸同功率下有较小的体积和重量。

构成金属与合金钝化的理论很多，主要有薄膜论、吸附论及电子排列论。碳在不锈钢中的两重性碳是工业用钢的主要元素之一，钢的性能与组织在很大程度上决定于碳在钢中的含量及其分布的形式，在不锈钢(不锈钢线材)中碳的影响尤为显著。碳在不锈钢中对组织的影响主要表现在两方面，一方面碳是稳定奥氏体的元素，并且作用的程度很大(约为镍的3倍)，另一方面由于碳和铬的亲和力很大，与铬形成系列复杂的碳化物。所以，从强度与耐腐烛性能两方面来看，碳在不锈钢中的作用是互相矛盾的。

窍门二：拉手、执手锁等锁具拉手的材料有锌合金、铜、铝、不锈钢、塑胶、原木、陶瓷等。为了与各种风格的家具配套，拉手的形状、色彩更是千资百态、五彩缤纷。经过电镀和静电喷漆的拉手，具有耐磨和防腐蚀作用，选择时除了与居室装饰风格相吻合外，还应能承受较大的拉力，一般把手应能承受6公斤以上的拉力。窍门三：检查贴面家具拼缝严不严不论是贴木单板、PVC还是贴预油漆纸，都要注意皮子是否贴得平整，有无鼓包、起泡、拼缝不严现象。
