What are the reasons for the shaft current generated by brushless motors?

Have you ever encountered situations where brushless motors occasionally generate axial current while using them? What is the reason for this?
1. The magnetic field of a brushless motor is asymmetric.
2. Poor manufacturing and installation result in rotor eccentricity and uneven air gap.
There is a gap between the two semicircles of the detachable stator core.
The current supplied to the brushless motor DC reduction motor fluctuates.
5. The number of stator cores stacked in a fan-shaped manner is not appropriate.
This is the reason why brushless motors cause axial airflow, and everyone knows it. Brushless motors have the advantages of high efficiency, low energy consumption, low noise, long lifespan, high reliability, servo control, stepless variable frequency speed regulation, low cost, and easy use.
