18. Method of Design Evaluation of SRM Lifetime and Ensuring its Long-Term Operation

Annotation: Based on generalization and analysis of Yuzhnoye SDO’s extensive experience of developing the SRM of various types, the dependences of their service life on main operative factors are determined. The techniques of engineering evaluation of operability margin of newly developed SRM are considered based on the methods of taking into account the breaking stresses and accumulation of damages (breaking deformations). An algorithm of engineering evaluation of SRM service life is proposed and the recommendations were elaborated to ensure long operation of the motors.
