Ⅰ. AIP Redefines Reliability in Motor Insulation Testing

AIP, a globally recognized motor tester brand, has recently completed the delivery of a customized three-phase motor stator tester for a leading industry customer.

Designed specifically for high-power motors, this tester addresses long-standing challenges in surge testing, including insufficient energy output, limited accuracy, and low testing efficiency. By adopting military-grade design standards, AIP delivers a reliable and future-proof solution for critical motor testing applications.

Ⅱ. Industry Challenges in High-Power Surge Testing

In practical high-power motor production and maintenance, conventional surge testing methods face several critical limitations:

1. Outdated testing methods: Early destructive tests required operating motors at 130% rated voltage for extended periods, causing high energy consumption and product damage

2. Manual interpretation: Traditional high-voltage impulse comparison relies heavily on manual waveform evaluation, leading to inconsistent results

3. Reference degradation: “Standard motors” used as baselines degrade over time, resulting in inaccurate comparisons

4. Insufficient test energy: Conventional surge testers lack the energy required to excite micro-defects, increasing the risk of undetected failures

These limitations create significant quality risks for manufacturers of high-power motors.

Ⅲ. AIP’s Integrated Motor Tester Solution

The delivered system is a highly integrated motor tester, offering a decisive competitive advantage over conventional equipment through the following innovations:

1. Intelligent Digital Analysis

By combining high-speed A/D sampling with advanced digital waveform processing, analog attenuation waveforms are converted into high-resolution digital signals.

Dedicated algorithms automatically calculate key parameters such as area, differential product, and phase shift, enabling precise and objective detection of surge short circuits—eliminating human judgment errors.

2. Military-Grade Energy Output

The tester employs military-grade thyristors as switching devices, paired with a customized energy storage unit.

This design delivers instantaneous high-energy surge pulses with peak currents reaching hundreds of amperes, significantly improving defect excitation capability and ensuring zero missed detection.

3. Wide Application Compatibility

Supporting coil inductance above 10 μH, the system features voltage closed-loop feedback and a fully modular architecture.

It supports series, parallel, and multi-station configurations, enabling rapid adaptation to different motor models and production requirements.

4. One-Stop Integrated Motor Testing Platform

The AIP motor tester integrates multiple core testing functions, including: Surge/AC Hi-pot/Inductance/DC resistance/Insulation resistance.

Equipped with 26 independent test channels, the system enables one-time wiring and one-stop testing, completing a full test cycle in less than 7 seconds, dramatically improving production throughput and testing efficiency.
