Diagnosis of Composite Materials In Electrical Machines

The most loaded parts of electrical machines are the shaft, the rotor sleeve, the stator teeth, and the bearings. This means using composite materials in these parts requires diagnostic systems to determine the residual life and to prevent emergencies. This paper presents methods for non-destructive testing of products made of composite materials. It describes the known methods for controlling the conditions of electrical machine parts made of composite materials. The paper also presents the developed method for eddy-current control of rotor sleeves made of carbon fiber.
