New analytical accurate approximations to the evaluation temperature dependence of heat capacity and electrical resistivity of motor winding are presented. The approach is based on the Debye method and Bloch-Gruneisen theory for controlling the heat capacity and electrical resistivity of motor winding with variation of temperature. This analytical evaluation is general and it shows that the results of motor winding heat capacity and resistivity are satisfactory for the wide range temperature variations. Comparison of the calculation results with the other literature data show that our approach is accurate and efficient.
