This tester is essential for manufacturers of traction motors, excelling in testing:
The VM-1AT is a 1KV digital surge tester with a bar-to-bar test feature, designed for testing small to medium DC armatures, series-wound field coils, and low-voltage DC traction motor windings.
The VM-1AT (1KV) is designed for smaller DC armatures at lower voltage ranges, offering a cost-effective solution for compact motor manufacturing. The VM-3AT (3KV) covers a wider voltage range and is specifically built for railway-grade DC traction motors requiring higher surge test voltages.
The bar-to-bar test detects inter-bar insulation faults and turn-to-turn shorts at the commutator level — defects that standard coil-to-coil surge testing cannot identify. It is essential for ensuring the quality of DC armatures before assembly.
Yes. The integrated LabVIEW software generates detailed test reports with waveform data, percentage error analysis, and model identification, which can be stored, recalled, and printed.
Small to medium DC armatures, series-wound DC motors, field coils, and low-voltage DC traction motor components in manufacturing and repair environments.
