First part of our article "Diagnostics of electric motors. The spectral analysis of vectors Park modules of a currents and voltages" published in magazine "News of Electrical Engineering", 1(49) 2008

Program of motor diagnostics and monitoring is expanded for cases of motor start; that is especially actual for motor of fire fighting systems. Besides at start motors work in most intensive regime, therefore malfunctions available in it are shown in a greater degree, than in stationary operating motor mode.

Again about Vibration Analysis vs. Motor current signature analysis Materials on this item "COMPARATIVE ANALYSIS OF ELECTRICAL AND MECHANICAL FAULT SIGNATURES IN INDUCTION MOTORS" Main conclusion: "The results from the electrical signatures provide a consistent indication of the same faults in the electric current indicators for the different fault cases."
