Plastic package brushless direct current motor for fan

The invention provides a plastic package brushless direct current motor for a fan, and relates to the field of brushless motors. The supporting and reinforcing structure is installed behind the plastic package brushless direct current motor, the interior of the front end of the flow guide plate structure is of an arc-shaped structure, the position of an included angle in the front end of the interior of the flow guide plate structure is of an arc-shaped structure, and the flow guide plate structure is connected with the supporting head structure through the outer rod structure. The inner end of each supporting head structure is fixedly provided with two insertion rod reinforcing structures of a cylindrical structure. During fixing, the metal inserting rod reinforcing structure is inserted into the inserting hole of the connecting assembly and is supported in the plastic connecting assembly, the strength of the connecting assembly is improved, the bolt applies pressure to the metal connecting assembly, the con
