光盘驱动电机的生产需要满足超高机械精度的要求。为了达到光盘驱动器的高品质，所有驱动内的单元需要经过一系列测量环节。生产要求的公差小于5 μm，且需要在正常转速下进行测量，米铱公司为此提供了高速，高分辨率的capaNCDT系统。此处，两支量程50 μm的电容型传感器应用到法兰盘几何尺寸的测量当中。

The production of disk motors has to meet the highest mechanical accuracy requirements. In order to ensure perfect functioning of the disk drives the drive units are measured and evaluated with respect to diameter, true running, and axial running. Since production tolerances of < 5 μm have to be measured under nominal speed, a decision has been made to use the fast and high resolution capaNCDT system. In this measurement two sensors with measurement range50 μm that are adapted to the flange geometry are of special importance
