New energy vehicles refer to vehicles that use unconventional automotive materials as their power source. They are mainly driven by motors, but must limit the quality and curb weight of the battery pack.The motor is the flywheel of the engine and plays a role in regulating the engine output power. Due to the special nature of the motor, the sealing requirements for it are very strict.First of all, we need to make sure that the motor housing is sealed, otherwise there will be a risk of electric leakage when the motor is driven.

There are various types of motors, and it is difficult to detect their sealing.Different manufacturers have their own methods for testing motor sealing, but the test results are all unsatisfactory in terms of accuracy.Among them, Hirays Technology is very experienced in testing this kind of motor.There are mature sealing testing solutions for different products and motors with different powers, which are suitable for different motor sealing testing and waterproofing identification.

1. Appearance display of new energy vehicle motors

1. What was inspected this time was a common new energy vehicle motor. It is an irregular polygon, and the shell is cast from silver-gray waterproof shell material. In order to ensure that the motor can work normally, the shape of the motor has been specially processed.

2. There are two steel pipe openings on the uneven casing of the motor, and the back of the motor is a raised assembly opening for docking other components.Two output wires are connected below the motor.

2. Difficulties and breakthroughs in detection of new energy vehicle motors

1. The special structure of the motor makes it difficult to detect its sealing. During the early design and production process of the motor, its shell will be specially treated, and the butt steel pipe and connected wires serve to connect the outside. During the test, the mold cannot be used for fully enclosed testing;

2. In view of the special shape of the new energy vehicle motor, the customer's demand is to detect the sealing of the cavity. We help the customer customize the testing plan and use the direct testing method to test. We help the customer develop a tooling mold based on the customer's product. Combined with our instruments, we use the pressure decay method to test the sealing of the product, and determine whether the new energy motor is leaking through the pressure change of the gas.

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent.

2. Patented technology independently developed by Hirays."IVT pneumatic sealing valve island", greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved.

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently, single selected and combined to meet various complex testing requirements.

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn.

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.The optional electronic pressure regulating valve can realize multiple sets of pressure sequential tests.

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols.

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.

10. Ultra-high stability and ease of use have passed the rigorous test of the market.

11. A variety of accessories are available, including inflatable bypass, quick connector, and standard leak hole. At the same time, the instrument supports third-party calibration and can issue a calibration report.
