Our Quality Testing Process
UT Testing – Ultra Sonic Testing (Railway)
(Bar to Bar, Hipot)
Spin Test Performance Characteristics for Stability
Delta Total Indicated Run Out
The measurement of concentricity of the bore compared to the commutator brush surface. Extremely tight tolerances have to be met. The test ensures the commutator will be aligned with the armature shaft and reduce wear on the armature and brushes.
Delta Bar to Bar
Measures the movement from bar to bar. Extremely tight tolerances have to be met. The extreme tolerances do not allow for conventional methods of measuring. These characteristics are measured with a vision/touch-less system
Requested by specific customers, this test measures the change in diameter of the commutator.
