About 50-70 % of all energy produced in the world is consumed by the electric drive. However, its operation is often accompanied by the appearance of various kinds of defects and damage caused by poor-quality manufacturing, failure of individual elements of electric motors without loss of performance. It results in more energy consumption and premature repair of electrical equipment, and an increase in material costs and enlarged use of energy resources.
