伺服是一个闭环控制系统，而变频器通常工作于开环控制，所以无论从速度还是精度上，变频器都无法和伺服相比。
其实变频只是伺服的一个部分，伺服是在变频的基础上进行闭环的控制从而达到更理想的效果。
变频器只是一个V-F转换，用于控制电机的一个器件。而伺服是一个闭环的系统。简单说变频器主要控制电机的转速。伺服是既可以控制速度，又可以控制位置和移动量，力距，定位，从而达到、稳定，不会因变频而产生死机。伺服不仅能达到以上的功能，而且产生一个闭环的系统，从而避免变频器产生的辐射。变频器在变频过程中还会产生大量热量，造成温度的提高与声音，而伺服系统是不会产生这样的后果。所以说伺服系统的达到的效果是变频电机无法比拟的。

一般为了节约用水，人们都会在用洗水液搓手时关闭水龙头，再打开时就会出现麻烦了，擦了洗水液的手再拧水龙头比较滑，而且水龙头也容易沾上洗水液，使用长久了会使得水龙头出现松动并且受到腐蚀等等情况。抬启式只需往上一抬即可出水，可用开启的角度大小来控制水流，方便卫生。感应式水龙头只要把手伸到水龙头下，便会自动出水，但反应迟钝。使用方便，既卫生又节水。扳手式一般只需旋转9度，可用开启的角度大小来控制水流。总之，不同开关方式的水龙头具有各自不同的优势特点，到底选择什么样的水龙头才好呢？这具体还得根据消费者的实际使用情况进行分析。

从故障诊断到预测性维护
　　随着机器安全标准的不断发展，传统的故障诊断和保护技术已经落伍，的产品嵌入了预测性维护技术，使得人们可以通过Internet及时了解重要技术参数的动态趋势，并采取预防性措施。比如：关注电流的升高，负载变化时评估尖峰电流，外壳或铁芯温度升高时监视温度传感器，以及对电流波形发生的任何畸变保持警惕。
　　专用化和多样化
　　虽然市场上存在通用化的伺服产品系列，但是为某种特定应用场合专门设计制造的伺服系统比比皆是。利用磁性材料不同性能、不同形状、不同表面粘接结构和嵌入式永磁转子结构的电机出现，分割式铁芯结构工艺在日本的使用使永磁无刷伺服电机的生产实现了率、大批量和自动化，并引起国内厂家的研究。
小型化和大型化
　　无论是永磁无刷伺服电机还是步进电机都积极向更小的尺寸发展，比如20，28，35mm外径;同时也在发展更大功率和尺寸的机种，已经看到500KW永磁伺服电机的出现。体现了向两极化发展的倾向。
