FAQ's

It is used for rapid quality control of single and three-phase motor windings in production environments. It detects inter-turn shorts, insulation defects, and coil asymmetry — including single turn shorts — ensuring defective motors are identified before leaving the factory.

An automatic surge tester applies preset voltage, captures the waveform, and gives an instant pass/fail decision without manual waveform analysis. A manual digital surge tester requires an operator to compare waveforms. Automatic testers are faster for production line use; manual testers offer more in-depth diagnostic capability.

Yes. The VM LCD-3AND is highly sensitive and can detect even a single turn short in a winding — making it suitable for the strictest motor winding quality control requirements.

 

Yes. It is specifically designed for testing fan stators (ceiling, table, exhaust), BLDC motor stators, pump stators, mixer motor field coils, and automotive starter/alternator windings.

The 3KV model tests low-voltage motor windings (up to approximately 1KV rated voltage). The 5KV model covers a wider voltage range, suitable for motors rated up to ~2KV and medium-range industrial motors. Choose based on your motor's rated voltage.
