The main objective of this paper is to help in solving the most important research and engineering problem -precision of non-contact inspection of mechanical condition of mechanisms and machine elements either in steady-state or in dynamic mode. Due to safety and economical reasons the interest to diagnostic and monitoring systems is growing rapidly in industry in all complex industrial production lines and power plants. Key components of power plants are rotating machinery like mills, blowers, water pumps and turbines. Diagnostic systems help to prevent severe failures. The designed complex provides acquisition of objective information concerning mechanical conditions of important mechanisms and machine elements at technological process stage and during lifetime period in the operating mode, which cannot be done by the majority of traditional measuring systems. With the help of the designed diagnostic complex and special mathematical processing methods, the unique experimental data concerning the change of commutator profile of high-speed electric machines during the lifetime period, shape and value of bearing vibrations were collected.
