The alteration of the energy parameters and losses components of electric machines in the process of their aging

The approaches to the determination of the energy indices of electric machines basic types via separate loss components in the function of their integral and instantaneous values are proposed. Their adequacy is confirmed and the special features of their use at the alteration of electric machine structural units and elements in the course of long-term operation and repairs are substantiated. The problem of the assessment of the change of the energy parameters of electric machines in the course of their aging is solved at the qualitative level.
