Stator Inter-Turn Stress with Electrical Signature Analysis in Variable Frequency Drive Applications
Incorrect settings in a Variable Frequency Drive (VFD) application have an impact on the windings of an electric motor. When a drive is not set correctly, or not tuned when not using straight volts/hertz settings, stresses occur between the turns in a winding. In some cases, this will appear as small Partial Discharges (PD), and in others it can be increased leakage between turns. When these conditions occur, they introduce small current discharges that effect the air gap magnetic field of the motor.
