Magnetic field monitoring
Rotor pole flux measurement is very important part of machine condition monitoring helping in detection of rotor pole shorted turns and rotor geometry problems. Problems that occur from irregularities in magnetic field can result with high vibrations occuring with field flash as a result of thermal or magnetic unbalance.
