交流伺服电机的基本类型
长期以来，在要求调速性能较高的场合，一直占据主导地位的是应用直流电动机的调速系统。但直流电动机都存在一些固有的缺点，如电刷和换向器易磨损，需经常维护。换向器换向时会产生火花，使电动机的速度受到限制，也使应用环境受到限制，而且直流电动机结构复杂，制造困难，所用钢铁材料消耗大，制造成本高。而交流电动机，特别是鼠笼式感应电动机没有上述缺点，且转子惯量较直流电机小，使得动态响应更好。在同样体积下，交流电动机输出功率可比直流电动机提高10﹪～70﹪，此外，交流电动机的容量可比直流电动机造得大，达到更高的电压和转速。现代数控机床都倾向采用交流伺服驱动，交流伺服驱动已有取代直流伺服驱动之势。

减速器是原动机和工作机之间的独立的闭式传动装置，用来降低转速和增大转矩，以满足工作需要，在某些场合也用来增速，称为增速器。
选用减速器时应根据工作机的选用条件，技术参数，动力机的性能，经济性等因素，比较不同类型、品种减速器的外廓尺寸，传动效率，承载能力，质量，价格等，选择的减速器。 [编辑本段]减速器分类 减速器的类别、品种、型式很多，目前已制定为行（国）标的减速器有40余种。减速器的类别是根据所采用的齿轮齿形、齿廓曲线划分；减速器的品种是根据使用的需要而设计的不同结构的减速器；减速器的型式是在基本结构的基础上根据齿面硬度、传动级数、出轴型式、装配型式、安装型式、联接型式等因素而设计的不同特性的减速器。

一般在35转/分以下转速的电机大多采用CM游隙，如高温高速电机则要求采用相对较大的游隙。INA轴承游隙在装配后会因为内孔的涨大及外圆的缩小而导致减少，游隙的减少量=过盈量×6％（轴承室是铝的除外）。比如INA轴承装配前游隙是.1mm，装配时过盈量为.1mm，则INA轴承装配后的游隙为.4mm。在理论上INA轴承在零游隙时噪音和寿命都达到的状态，但在实际运转中考虑到温升等问题，INA轴承在装配后游隙为.2mm-.4mm较好。

IKO轴承断裂失效主要原因是缺陷与过载两大因素。当外加载荷超过材料强度极限而造成零件断裂称为过载断裂。过载原因主要是主机突发故障或安装不当。轴承零件的微裂纹、缩孔、气泡、大块外来杂物、过热组织及局部烧伤等缺陷在冲击过载或剧烈振动时也会在缺陷处引起断裂，称为缺陷断裂。应当指出，轴承在制造过程中，对原材料的入厂复验、锻造和热处理质量控制、加工过程控制中可通过仪器正确分析上述缺陷是否存在，今后仍必须加强控制。
