Abstract:

The Linear Induction Motor (LIM) is a rather simple machine as it does not have any moving (rotating) parts. It can be thought of as a radially cut and flattened rotary motor with the rotor laid continually under the now flat primary. In this configuration the electrodynamic forces produced by the motor are directly applied to the primary without any mechanical torque converter (gearbox). Such force application makes the LIM propelled vehicle independent of adhesion and achieve desired  performance under varying environmental conditions. This presentation will discuss the advantages of the LIM motor in electric traction in comparison to a rotary counterpart, the challenges related to its application in modern transit systems and peculiar phenomena associated with its operation, impacting its construction and controls.
