Abstract: The urgency of the discussed issue. The electrical drives based on squirrel-cage induction motors are widespread now. Identification of current state of these motors is difficult because rotor parameters in these machines are unavailable for direct measurements. Moreover using of sensors may be difficult or undesirable. At the same time drive control system needs information about motor state, especially about rotor speed and electromagnetic torque. For these reasons we need to use the model of motor which computes current motor state using some a priori known parameters and the minimum of measurements. The main aim of the study: design of model for induction motor using passport parameters and measurement RMS of stator phase voltage and current. The methods used in the study: method of two-phase generalized electrical machine, method of equivalent circuits, computer simulation. The results: mathematical model of asynchronous motor are obtained and tested using the computer simulation

Key words: mathematical model induction motor equivalent circuit generalized electrical machine electromagnetic torque
