Full Runout Measurement of DD Motor End Face Based on Point Cloud Drive
The total lateral runout of the direct driver (DD) motor directly affects the positioning accuracy of DD. In real-time production, face runout is measured using dial indicators because of the complex measurement process for total face runout. This method can easily damage the surface of the measured object and is associated with inefficiency and low precision. To address this issue, a method to measure the DD motor end face runout based on point cloud driving is proposed. In this method, the point cloud on the DD motor surface is obtained using a linear laser sensor that incorporates laser triangulation to measure the distance of the object. The Z-axis measurement accuracy is 1.8-3.0 μm, and the repetition accuracy is
