Ⅱ. What kind of test is the automotive motor PD test?

Automotive motor PD testing is automotive partial discharge testing.

Automotive motor PD test is a test to detect partial discharge phenomenon in the comprehensive motor and stator of a new energy vehicle drive motor. Partial discharge is a phenomenon that occurs when the electric field strength in the insulating material reaches a certain level, due to defects or damage within the insulating material. This phenomenon, if not detected and dealt with promptly, can lead to failure damage to the motor, which in turn affects the stability and reliability of the vehicle.

III. Principle of partial discharge of automobile motor

Auto motor PD partial discharge refers to the phenomenon of discharge in localized areas inside electrical equipment under high voltage. When the voltage rises to a certain level, the insulating material inside the automotive motor may have localized damage or defects, and these defective areas will form a concentrated area of the electric field under the action of voltage, which will lead to partial discharge.

In automotive electrical equipment, the insulation layer of electrical equipment is affected by various factors, such as heat, vibration, and chemicals, due to frequent changes in voltage and current. These factors may lead to damage or defects in the insulation layer, resulting in the PD phenomenon. The occurrence of partial discharges can cause a degradation of motor performance, as well as accelerate the aging and damage of the insulation layer, which can lead to failures.

To avoid the occurrence of partial discharge in the PD of automobile motors, damage and defects in the insulation layer can be detected and dealt with in time by carrying out factory PD inspection of automobile motors.

IV. Summary

The motor partial discharge tester is AIP's key innovation in the field of motor testing, providing critical support for the safety and reliability of automotive motors. Through high-precision monitoring and analysis, it can effectively prevent electrical insulation failures, extend motor life, reduce maintenance costs, and improve overall vehicle performance and experience. In the future, as technology advances and market demands change, AIP will continue to work on optimizing system performance and advancing motor PD testing technology to meet customer needs for safe, reliable, and high-efficiency automotive motors.
