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 .
