Although Shanghai Motor (Shanghai Electric Machinery Factory Co., Ltd.) and Shangdian Motor (Shanghai Shangdian Electric Co., Ltd.) share similar names and a common origin, they have each evolved into distinct entities in terms of corporate nature, operational scale, product positioning, and market standing.

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.

The insulation class of high-voltage three-phase asynchronous motors is a core technical indicator defined based on the maximum allowable operating temperature of the insulation materials.

The five core performance parameters of a motor are key indicators for evaluating its performance, suitability for application scenarios, and selection criteria. They directly determine the operating state and effectiveness of the motor, including rated power, rated voltage, rated current, rated speed, and rated frequency.
