Linear induction motors are applied in equipments with different requirements set up to the controlled motion parameters. Investigation of motoring and breaking modes remains the relevant problem nowadays. The scientific novelty is based on analysis of non-symmetrical operation modes of linear induction motor at supplying it by a voltage source, developing a generalized model of motoring and breaking dynamic modes and analyzing influence of linear motor windings connection way and control parameters on dynamic breaking characteristics. The coordinate transformations of linear induction motors dynamic models, based on rotational motor with assumptions valid for low speed motor and multi-pole motor, are considered. Mathematical and computer models to investigate symmetrical dynamic modes of linear induction drives are presented. Generalized model to investigate non-symmetrical dynamics modes is elaborated. The results of simulation are presented by dependences on the main variables in the time domain, and dependences on both constructional and control parameters that give possibility to optimize constructional parameters of motors.
