Damage to the motor coil will cause insulation problems during the operation of the motor, resulting in faults such as excessive working current, excessive temperature rise, and housing electrification, which will directly affect the operation of the equipment. Therefore, surge impulse withstand voltage is crucial for motor quality testing.

01. Iterate to meet demand

How to accurately test the motor's inter-turn withstand voltage has always been a topic that the AIP R&D team has worked hard to solve. Since its establishment, AIP has focused on studying various motor characteristics. The first generation of surge tester launched by AIP realizes intelligent testing, reduces the professional requirements of operators, is efficient and accurate, and has become a classic product in the industry.

In order to meet the ever-changing market demands, AIP continues to invest in technology research and development, and has launched a series of more intelligent second-generation surge tester with a higher sampling frequency and a high-voltage closed-loop feedback function.

The first generation of surge tester

Functional features: up to 100 groups of test condition memory, upper and lower limit alarm function, surge standard waveform storage in sequence, full-automatic voltage regulation mode, etc.

Product application: Suitable for surge withstand voltage test of various small-power motor stators and coil products.

The second generation of surge tester

Functional features: The sampling frequency is increased to 100MHz, and high-voltage closed-loop feedback can be achieved. A 10.4-inch touch screen is added, supporting networking, realizing automatic testing, data interaction, and resource sharing.

Product application: Suitable for surge withstand voltage test of various small-power motor stators and coil products.

02 Third-generation high-power motor tester

Since the first and second generation surge voltage withstand testers are mainly used for testing low-power motors, their accuracy cannot meet the needs of high-power motor surge testing. Based on years of experience, AIP has devoted itself to studying the characteristics of high-power motors and successfully launched the third generation of high-power motor surge tester.

The system adopts a new design concept, based on the technical foundation of the previous two generations, and has comprehensively upgraded the sampling frequency, energy storage capacitor, output energy, switching devices, etc. It has the advantages of fast test speed, ultra-high precision, ultra-large surge energy, and military-grade standards. It can be widely used in surge testing of high-power motors such as three-phase industrial motors, new energy vehicle drive motors, and permanent magnet synchronous motors.

03. Core Competitive Advantages 

1. Accurate intelligence:

This product uses a high-speed A/D test system to digitize the surge waveform through a high-voltage pulse waveform comparison method, and automatically stores, analyzes, and judges the test data based on a specific computer algorithm. It can accurately identify the inter-turn short-circuit problem of adjacent turns of the motor.

2. Military-grade standards:

This product uses military-grade electronic components. Compared with traditional surge testers, the impact current can reach several hundred amperes, which can greatly improve the detection rate of defective products and solve the problem of low energy in long-term high-power three-phase motor surge testing.

03. Application results

So far, AIP's one-stop motor surge testing solution has served thousands of customers around the world, covering multiple scenarios such as production lines, laboratories, and motor maintenance. AIP also provides strong support for global motor testing with its strong technical R&D strength and practical application capabilities.
