   “ SF ” 系列稀土永磁直流伺服电机包括 ZSD系列直流电动机和ZYS型直流测速发电机，具有恒转矩调速，调速范围宽；转动惯量小，动态响应快，连续运行平稳；低速运行时能保持良好的性能并能承受较高的负载变化率以及体积小，重量轻，噪音低，结构简单，安装方便等特点，特别适用于需要平滑调速，效率高，自动稳速，反应灵敏的控制系统。其作为电气自动化伺服系统的执行元件，和直流驱动装置配合，被广泛地运用于机器人技术，数控机床，印刷、包装机械，线材加工机械，橡胶、塑料机械，试验测试仪器，雷达跟踪，通讯传输，海洋勘探等众多领域。

   “ SF ” brand of thulium earth permanence-magnet motors including ZSD series DC electric servomotor and ZYS series DC tachometer motor, which are provided with invariableness torque adjustment, wide speed adjusting, lower inertia ratio, fast dynamic response, excellent continuous and stable operation; they are also being with well capability to bear high overload transformation when they works in low speed. The motors are made with small volume as well as light weightiness to be mounted very convenient. It is especially suitable for control systems which ask for adjusting speed smoothly, saving energy, leveling off speed automatically and response quickly. Acting as perform element of automatic electric serve system, the servomotors are widely adopted in automaton technology, NC machine, print & packing machine, cable processing machine, plastic & rubber machine, surveying instruments, radar tracking, communications, sea prospecting and so on.
