变频器和伺服驱动器都是交流电机的驱动器，工业应用中，速度控制和力矩控制的场合要求不是很高的一般用变频器，有严格位置控制要求的场合中只能用交流伺服驱动器来实现。此外，伺服的响应速度远远大于变频，有些对速度的精度和响应要求高的场合也有用交流伺服驱动器控制。

以往，国内变频器企业实力与规模参差不齐，进口产品占据了国内变频器市场的大部分份额。近年来，本土变频器品牌经过多年发展，逐步扩大了市场占有率，并从单纯的提供产品开始转变为为用户提供系统化的解决方案。目前，市场上的变频器正逐渐走向多元化，通用型、型产品的出现，满足了用户的多样需求，为攻占市场提供了基础。

交流伺服驱动器的发展趋势是通用化、智能化、网络化和模块化。通用型驱动器配置有大量的参数和丰富的菜单功能，便于用户在不改变硬件配置的条件下设置成各种不同的工作方式，适用于各种场合，可以驱动不同类型的电机;现代交流伺服驱动器都具备参数记忆、故障自诊断和分析功能，有的可以自动辨识电机的参数，自动测定编码器零位，有些则能自动进行振动抑止;随着国内对大规模分布式控制装置的需求上升，数控系统的开发成功，网络化数字伺服的开发已经成为当务之急。
