Abstract

This work presents a new vibration diagnostic method of permanent magnets (PM) traction motors. Those machines are frequently used in electrical vehicles. The described method is very unique and innovative. Characteristic properties of PM machines are used in this method - EMF generated due to vibrations. There was analysed number of publications which describe vibration diagnostic methods and tests of electrical machines with permanent magnets and there was no method found to determine the technical condition of such machine basing on their own signals. The method of determination the technical condition of PM electrical machine basing on its own signals is the subject of patent application [1].
