Abstract

Analysis of mechanical and electrical diagnostic parameters of electromechanical units is considered as an integrated approach. The relationship between mechanical, electric diagnostic parameters and technical conditions of the electric drive is investigated on the example of the stand consisting of the asynchronous motor, the coupling and a worm gear. The most sensitive diagnostic parameters were identified in case of various defects in electromechanical units. The change in the spectrum of vibration of the motor and the coefficients of the wavelet analysis of the electric current of the motor stator were investigated at idle and under load, in the absence and presence of the following defects: a decrease in the contact patch gear, misalignment coupling rims, as well as grazing rotor motor.
