Motor Stator Comprehensive Tester

1、Equipment description

The WS530XA/B-E series DC brushless motor stator comprehensive tester integrates six testing functions: electrical strength (AC withstand voltage), insulation resistance, inter-turn impact withstand voltage, DC resistance testing, rotation direction testing, and inductance testing. Features large LED display, touchscreen operation, high precision, and high efficiency. It is an essential testing device for motor manufacturers and quality inspection departments. This tester is independently developed and produced by Yidi Electronics, with advanced technology, automation, and performance in the industry.

2、Basic Knowledge of Inspection Items

Insulation resistance test: Insulation resistance reflects the performance of insulating materials. This item can assess the insulation performance of the tested object, moisture or contamination of insulation, mainly measuring the insulation resistance between the coil and the iron core or between coils.

AC/DC withstand voltage test: Also known as electrical strength test, it confirms whether to perform AC or DC withstand voltage testing based on the power environment of the tested product. By applying sustained high voltage exceeding the rated voltage between the coil and between the coil and iron core, it verifies whether the energized parts of the tested product have breakdown phenomena. During testing, the insulation parts of the tested product endure abnormal stress, quickly revealing short circuits, breakdowns, or arcing.

DC resistance test: Measures the DC resistance of winding coils to detect short circuits, broken wires, or turn count discrepancies.

Inter-turn test: Measures high-voltage oscillation waveforms of the coil to calculate parameters and differences from standard coils, assessing coil quality.

Inter-turn area: Calculates the area enclosed by the waveform of the standard part and the tested part around the zero point, comparing differences and expressing as a percentage.

Inter-turn difference product: Calculates the ratio of the enclosed area of the waveform of the standard part and the tested part to the standard waveform area to judge waveform overlap.

Reverse embedding test: Used to measure the winding direction of the motor winding.

Magnetic rotation test: Measures the phase relationship between the main and auxiliary phases of the motor stator to infer the rotation direction.
