Investigation of Electromechanical Differences of Linear Induction Machine Operation Regions

The advantages of linear induction machines (LIM) to be applied in the transportation applications are that easy maintenance, no need for the transformation from rotary movement to linear movement, and robust operation to name a few. Control schemes with easy implementation and maximum energy conversion ratio (i.e. force/amp) has been proposed in the literature. In order to achieve maximum deceleration in this control scheme, electromechanical differences of motoring, generating, and electromagnetic braking are explored. It is shown that LIM can work in the region of electromagnetic braking. Simulation results are represented to validate the proposed control scheme.
