Dynamic Models of Asymmetric Induction Drive

Some types of induction motors such as linear induction motors because their constructional properties are asymmetrical as well as some kinds of revolving motors, designed for special purposes also are characterized by asymmetric magnetic and electric circuits. The article presents dynamic mathematical models of asymmetric induction drive with Y connected windings with neutral wire and without it, as well as with Delta connected windings. Calculated starting transients of linear motor speed, force, currents and consumed power are presented and analyzed. The greater asymmetry of motor currents leads to increase considered variables.
