Several Faqs of Nanyang AC Motor
First, why does the Nanyang AC motor generate shaft current?
The current in the shaft-bearing-basic circuit of a motor is called the shaft current.
Causes of shaft current:
(1) the asymmetry of the magnetic field;
(2) There are harmonics in the power supply current;
(3) The manufacturing and installation are not good, and the air gap is uneven due to the eccentricity of the rotor;
