= 0.215   0.00304 = 0.218 Nm

X轴制动转矩：Tsx =  (JLX Jm7)●a - TL

                      =0.441-0.035=0.406Nm

Y轴制动转矩：Tsy =  (JLY Jm4)●a - TL

=  0.215 - 0.00304 = 0.212 Nm

通过以上的计算选用的是松下MHMD400w和MSMD750w的交流伺服电机，该型号输出惯量

适合，运行更平稳。X轴用的是750w的伺服系统，额定扭矩为2.4Nm；而Y轴用400w的伺

服系统，额定扭矩为1.3Nm；这两款的额定转速都为3000rps；所选伺服的惯量及扭矩都能使载体平稳的运行。

（3）盘式电机选型

由于在盘式伺服上要放的是一个铝制的圆盘，圆盘规格(R=150mm  M=1kg  实心)：

圆盘惯量J=1/2?M?（D/2）?=1/2?1?（150/2）?=0.0028125 kgm2

扭矩T=角加速度a?惯量J  

圆盘转π/2需要的时间是4s，平均角速度V=π/2?4=0.3925rad/s

则：角加速度=角速度V/加速时间t=0.3925?0.01=39.25rad/s?

则：扭矩T=39.25?0.0028125=0.1104Nm    

由于惯量要匹配，盘式伺服承受物体的惯量和盘式伺服自身的惯量的比例在1：10之内是最理 想的，所以所选的盘式伺服ND110-50F自身的惯量是0.00034 kgm2、额定扭矩是2.4Nm最大扭矩是7.2Nm、回转速度是5rps、分辨率是720000 ppr。该盘式伺服的定位精度是±90s，重复定位精度是±18s，外加绝对值选项定位精度可达±15s、重复定位精度±1.8s。360度=1296000s，圆盘周长 L=πR=3.14?150=471000um，则角度1s=0.363um弧长，所以当定位精度为15s时圆盘的弧长精度可达到5.445um。
