Should the motor use a metal impeller or a plastic impeller?

The difference between metal fan blades and plastic fan blades: Fans with plastic blades have less wind noise, are light in weight, have low vibration, have small starting current, and have smaller motor power, but have a slightly shorter service life and poorer durability; metal blades have less wind noise It is larger, has high durability, large starting current, and slightly larger motor power.

At present, the main materials of motor fan blades include iron blades, aluminum blades, and plastic blades.

Their advantages and disadvantages are as follows: Iron blades: do not deform after long-term use and have a large air volume. However, if the quality of the blades is poor and the blade cover is not good, there is a hidden danger of breaking and flying out, injuring people, and consuming electricity; Aluminum blades: almost do not deform after long-term use, large air volume, lighter weight, more energy-saving and durable than iron leaves; plastic leaves: lightweight, energy-saving, but will deform after long-term use, feeling like there is no wind, and will deform again soon after correction.

The motor can also use a high-inertia flywheel fan to increase the inertial momentum of the motor and make the motor rotate at a smooth speed.
