Tips: The noise source of Nema 10 micro stepper motor.

The noise caused by the internal electromagnetic of Nema 10 micro stepper motor. Tooth harmonic noise is caused by improper cooperation between stator, rotor eccentricity and slot, as well as rotor imbalance.
Mechanical noise is a kind of frictional sound produced by mechanical parts of Nema 10 micro stepper motor such as bearings and bores.
The noise and whistle noise caused by the air duct. Fan rotation causes the gas to pulsate periodically. The air current hits the solid object and makes a monotonous sound. When the fan blades roll, the surrounding air emits a kind of vortex sound, and its frequency spectrum is relatively wide.
