The product has the characteristics of high precision, fast testing, strong adaptability, simple operation, modular design, intelligent design, remote diagnosis, easy maintenance, and rich interfaces.

Key Tests for Motor Windings

Motor stator coil manufacturing (using single or multiple wires) is prone to various faults: Connection errors, output errors, coil wire diameter errors, coil unit reverse embedding, incorrect turns count, poor insulation between surge, surge short circuit, poor insulation between phases, phase-to-phase short circuit, poor insulation between the winding and the core, winding-to-core short circuit, reverse embedding, etc.

To deal with the above adverse conditions, the motor coil tester has the following test items to choose from:

1.  DC Resistance Measurement：

Measures the DC resistance of each phase winding. Identifies incorrect wire gauge , severe shorts, open circuits, and excessive turn count deviation.

2.  AC Hi-pot Test：

Applies a specified high AC voltage between windings and the core for a duration to verify dielectric strength. Detects insulation breakdown risks or short circuits.

3.  Insulation Resistance Test：

Applies a DC voltage between the winding and core to measure insulation resistance. Evaluates winding-to-core insulation integrity, detecting leakage currents or potential shorts.

4.  Surge Test：

Applies a high-voltage impulse with specific waveform across windings.It can effectively identifies surge insulation failure, shorts, turn count errors,reverse coil embedding, and wiring mistakes through comparative waveform analysis.
