Abstract
In this paper an analysis of the resultant flux linkage vector ψ0 of double-way feed motor (DFM) in the vibrational-rotational mode is shown. It is used for vibration-based diagnostics of various equipment with AC drives. In the case of using DFM in the vibrational-rotational mode the accuracy of motion law implementation is higher than using the standart induction motor. The results of research obtained with the help of a mathematical model of the DFM that allows to explore the special operating modes such as oscillating, polyharmonical, vibrational-rotational and creeping speed ones. The urgency of DFM operational mode and its practical significance as a method of control for vibration-based diagnostics systems are also given herein. The influence of the load parameters on the dynamic parameters of the executive vibratory drive is shown. Keywords: vibrational-rotational operation mode, vibration-based diagnostic, double-way feed motor, resultant flux linkage vector, damping torque, transient time
