This system analyzes the commutator contour and calculates geometrical characteristics, after a "filtering" process removes the slots from the original profile.
The bench references the armature shaft on V journals, reproducing the machining condition.
BAR TO BAR: This is the vertical gap between the two adjacent edges on adjacent bars. All such gaps are calculated and the worst case is displayed. The typical tolerance is 3 µm. Values exceeding the tolerance have a dramatic influence on motor life.
