In this paper, the authors systematized and interpreted the results obtained by running their own design computing programs, developed using the facilities offered by the Mathcad mathematical software package combined with facilities offered by appropriate custom chart wizard, provided by Excel. These programs were developed based on the algorithms for calculating the parameters of the equivalent scheme, the electrical balance components and the energy efficiency indicators (efficiency, power factor) for a three-phase induction motor with squirrel cage rotor with deep rectangular bars within the ancillary services of a thermoelectric power plant, using a complete mathematical model for different degrees of loading.
