The problem of reparable coefficient determination for electrical machine failure model is examined. This coefficient takes into account loading and exploitation mode influence by means analysis of electric, mechanical and thermal processes that flow in it.
Dependence between maximum admissible current value and temperature models parameters is discussed in this article. Used temperature model also allow for dynamic power loss of electrical motor. This dependence allows to limit maximum current value of induction motor according to variable temperature conduction of electrical machine.
