The glitches that motor cannot get used to

Why do motors generate shaft currents? The current in the shaft-bearing housing-base circuit of a motor is called shaft current. Causes of shaft currents:[1] 1. Asymmetry of the magnetic field; 2. Harmonics in the supply current; 3. Poor manufacturing and installation, uneven air gap due to rotor eccentricity; 4. Gaps…
