Making Factories Smarter Through Machine Learning
Figure 5: Clustering results for Torque vs. Power Consumption in X-axis The distinctive Butterfly pattern, shown in Figure 5, represents a complete cycle of the servo motor axis. Clustering of data is shown with the blue data points related to acceleration, direction and peak power in given cycles – acceleration and deceleration – symmetric – around the 0 power. Green data plotted is similar to Blue but at different positions. Whereas the data plotted in Red reflects when the drive was stopped but where power and torque was still consumed to avoid movement while held in position. The data plot using the clustering technique produces a graphical representation that identifies the three states of the servo axis – acceleration, deceleration and the idle state to hold the position.
