EDCAST5 TEST SYSTEM Automatic test system for stators and coils

THE DEFECT YOU CANNOT SEE IS THE ONE THAT BREAKS THE MOTOR Stator quality is measured on two levels. WHAT STANDARD TESTS DETECT WHAT STANDARD TESTS MISS Permanent short circuits, open circuits, incorrect number of turns (winding resistance). Windings in contact between phases or with the core (dielectric strength). Turn-to-turn short circuits within the same winding (surge). Connection errors, rotation direction reversal (functional tests). A wire outside the slot brushing against the core, without damaging the enamel. A thin or scratched enamel coating at a single point of the winding. A hairpin...

A SINGLE PLATFORM FOR ALL ELECTRICAL TESTING CONFIGURABILITY SHARED BY BOTH VERSIONS ▶ ▶ ▶ Number of terminals: from 2 to 24 in standard configuration; higher configurations available per customer specification. Customizable test programs: test type, sequence, parameters and acceptance thresholds set by the customer. Built-in functions: result archiving, multilingual certificate and self-adhesive label printing, production statistics, self-diagnostics, software calibration, preventive maintenance, remote assistance. WOUND ROTOR APPLICATIONS The same AST5 platform runs the standard electrical...

THE TEST THAT SEES WHAT OTHERS MISS A Partial Discharge is a localized electrical discharge that only partially bridges the insulation between two conductors. It is not a short circuit, it is its precursor. Every discharge leaves a micro-erosion in the dielectric; repeated over time under voltage stress, it leads to failure. Measuring Partial Discharges at end-of-line means intercepting quality defects before they become field failures. Marposs E.D.C. laboratory tests on a sample stator and rotor simulate three realistic defects. Each defect leaves the results of standard tests unchanged (Resistance,...
