  • What is the difference between the routine test and the type test for high-voltage three-phase asynchronous motors?

    The core difference between the routine test (factory test) and the type test for high-voltage three-phase asynchronous motors is:
    The routine test is a "factory pass certificate" performed on every motor to verify the manufacturing quality of each unit. The type test is a "design validation report" performed on a sample from the same specification to verify the design and performance compliance of the entire series.
