Abstract

A method and apparatus for monitoring and ascertaining respective changes in an operating condition of an electrically operated engine that occur due to stress. Operating parameters are measured to acquire the influences of different types of stresses which promote the wear of the engine. The operating parameters are transferred to an electronic, non-volatile memory module. The operating parameters are converted to respective wear contributions indicative of a degree of wear of the engine. The wear contributions are evaluated to determine the actual wear of the engine at any point in time.
