Abstract
The necessity of frequency-controlled induction motor study thermal state is determined by frequent failure of these motors due to overheating of the stator windings, especially in non-stationary modes. The determining method of frequency-controlled induction motor rotor’s winding thermal resistance, which are part of the frequency-controlled induction motor equivalent thermal circuit dynamic parameters are detailed considered in the paper. The mathematical model obtained based on the given thermal equivalent circuit used for the frequency-controlled induction motor thermal state research. The efficiency and adequacy of the obtained frequency-controlled induction motor thermal state mathematical model are experimentally confirmed. The research results in previously published papers are detail considered [1-6].The paper material complements these papers and makes it easier for induction motor design professionals to study and use the given method.
