The GB/T 22715 - 2008 standard focuses on the impact voltage level of the stator forming coil of the AC motor. It specifies the relevant technical requirements and test methods, covering the specifications of the test equipment, the specific parameters of the impact voltage applied, and the judgment criteria for the test results. Through this standard, the ability of the stator forming coil of the AC motor to withstand the impact of instantaneous high voltage can be accurately detected. This is of great significance for the motor manufacturer to control the mass of the product and ensure the stable operation of the motor in the complex power environment. It helps to reduce the risk of coil damage due to voltage Impact, prolong the service life of the motor, and improve the Reliability of power equipment.
