This tester is essential for manufacturers of traction motors, excelling in testing:
A bar-to-bar test applies surge voltage between each pair of adjacent commutator bars in a DC armature, detecting turn-to-turn shorts and inter-bar insulation faults at the commutator level. It is essential for DC traction motors where standard coil-to-coil testing misses commutator-level defects.
The VM-6KA is designed for DC traction motors, series-wound armatures, field coils, and AC/DC motor combinations — particularly used in Indian Railways, metro rail, and industrial DC motor manufacturing.
The VM-6KA operates at surge test voltages up to 6KV, suitable for low and medium-range DC armatures and AC motor coils. Contact us for models covering higher voltage armatures.
Yes. The integrated LabVIEW software generates detailed MS Word test reports automatically, including waveform comparison data, percentage error readings, and model identification.
A standard 6KV surge tester tests coil-to-coil insulation. The VM-6KA does all of that AND performs a bar-to-bar test at the commutator level — detecting faults that standard surge testers cannot identify in DC armatures.
