This invention provides a stator support structure and its processing method for a brushless blower motor, belonging to the field of automotive parts manufacturing technology. The invention uses aluminum sheet stamping to obtain a base plate with several support columns. Simultaneously, a plastic connector with several snap-fit ​​columns is injection molded on the base plate, located on one side extending from the support columns. The support columns achieve radial positioning and support of the stator structure, realizing high-precision coaxial positioning between the stator structure and the motor housing. The snap-fit ​​columns axially lock the stator structure, eliminating the problems of needing to tighten nuts and the tendency for loosening and accumulated errors associated with existing bolt connections. Furthermore, the lower-density plastic connector replaces the original aluminum and other metal materials, resulting in lighter weight. The use of a stamping-then-injection molding process for the base plate and plastic connector improves processing efficiency, avoids casting waste, increases material utilization, lowers manufacturing costs, and improves the motor's assembly accuracy and quiet operation.
