FAQ's

The VM-3AT tests DC traction motor armatures in the railway industry using a bar-to-bar test to detect inter-bar insulation faults, turn-to-turn shorts, and commutator defects in series-wound armatures and field coils.

The VM-1AT (1KV) targets smaller DC armatures in general industrial applications. The VM-3AT (3KV) covers a wider voltage range and is specifically built for railway DC traction motors requiring a higher surge test voltage for thorough insulation evaluation.

It is used in Indian Railways loco and EMU traction motor overhaul workshops, metro rail systems, mining haulage DC motors, and large industrial DC drive motor manufacturing facilities.

Its bar-to-bar test is specific to DC armatures. However, it can also perform standard coil-to-coil surge testing for AC motor windings within its 3KV voltage range.

Yes. The VM-3AT is designed to comply with IEEE and IEC electrical testing standards and is used in approved Indian Railways traction motor workshops.
