[0002] The matching between the fan blade and the motor is the main factor affecting the performance and energy efficiency of the fan. Generally, the fan blade is made of materials such as PP or PP-GF, which have low cost. However, due to the influence of the blade type injection molding process, the mold, and the environmental temperature, etc., the blade size is extremely unstable. Even within the tolerance range, the size difference of the blades is relatively large. And the motor driving the blade generally uses an oil-containing bearing motor, and the rotational speed tolerance of the motor is large.
