The Analysis of Own Signals of PM Electrical Machines – Example of Eccentricity

Authors: M. Barański


This article presents a vibration diagnostic method designed for Permanent Magnets (PM) electrical machines–traction motors and generators. Those machines are commonly used in traction drives of electrical vehicles and small wind or water systems. The described method is very innovative and unique. Specific structural properties of machines excited by permanent magnets are used in this method - electromotive force (EMF) generated due to vibrations. There was analyzed number of publications, which describe vibration diagnostic methods, and tests of electrical machines and there was no method found to determine the technical condition of such machine basing on their own signals. This work presents field-circuit model, results of static tests, results of calculations and simulations.

Keywords: Data Analysis, Diagnostics, vibrations, electrical vehicle, permanent magnet, traction drive, eccentricity, electrical machine, data acquisition
