ICC subjects all of its products to rigorous and extensive testing that is higher than industry standards, ensuring the highest quality product is delivered, and that customers remain satisfied with the high level of service and quality.
UT testing - Ultra Sonic Testing (Railway)
Ultra Sonic Testing uses high frequency sound energy to conduct examinations. The sound energy is introduced as a form of waves. The waves reflect back presenting spikes on the graph. If a flaw or fracture in the copper is present, the wave will not be generated on the graph. This ensures that the commutators are defect free.
This test ensures that the commutator (copper bars and Mica segments) is parallel to the bore centerline of the commutator.
Dielectric Testing (Bar to Bar, Hipot)
Performed to verify the electrical insulation in finished parts. Hipot test/Bar to Bar test verifies that the insulation of this product is sufficient to ensure minimal current leakage that can affect the overall performance of the commutators.
Spin Test Performance Characteristics
- 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 capabilities of these characteristics are measured with vision/touch-less controlled system. The repeatability are measured to 0.00001".
- Growth Requirement: Requested by specific customers, this test measures the change in diameter of the commutator.
