直流无刷电机的应用
无刷直流电机的应用十分广泛,如汽车、工具、工业工控、自动化以及航天等等。总的来说,无刷直流电机可以分为以下三种主要用途:
持续负载应用:主要是需要一定转速但是对转速精度要求不高的领域,比如风扇、抽水机、吹风机等一类的应用,这类应用成本较低且多为开环控制。
可变负载应用:主要是转速需要在某个范围内变化的应用,对电机转速特性和动态响应时间特性有更高的需求。如家用器具中的、甩干机和压缩机就是很好的例子,汽车工业领域中的油泵控制、电控制器、发动机控制等,这类应用的系统成本相对更高些。
定位应用:大多数工业控制和自动控制方面的应用属于这个类别,这类应用中往往会完成能量的输送,所以对转速的动态响应和转矩有特别的要求,对控制器的要求也较高。测速时可能会用上光电和一些同步设备。过程控制、机械控制和运输控制等很多都属于这类应用。

减速机等级数量增加,总减速机的效率降低。传动比为 100:1 时的效率低于传动比为 20:1 时的效率。要应对这种情况,在使用多级减速机时,应减少驱动级的功率消耗。可通过降低减速机密封件的摩擦损失或额外缩小齿轮几何形状执行驱动级的方式来实现。这样还会减少惯量,从而有利于动态应用。单级行星减速机的效率。
此外,通过各种类型的齿轮组合也可实现多级减速机。将斜齿轮减速机与行星减速机组合即可得到转角型减速机。此处的总传动比同样也是单一传动比相乘所得的值。根据齿轮类型和锥齿轮等级的规格,输入轴和输出轴的旋转方向可相反。
多级减速机的优点:
传动比范围广
对于行星减速机,始终保持同轴
结构紧凑,传动比高
可结合各种类型的减速机
应用范围广
多级减速机的缺点 (与单级减速机相比):
结构较复杂
效率较低
