Abstract
Linear induction motors (LIMs) have got potential to replace the age old belt-pulley driven systems and the likes, which are in use for conversion of rotary to linear motion in most of the applications. In the present work a 3-phase, 50 Hz, 4-pole, 220 V, 320 W, 2.5 m/s LIM has been designed, fabricated and successfully tested on a test track. 2-D finite element analysis of the LIM has been done with ANSYS 7.1 to evaluate typical field and circuit variables. The results are in good agreement with the analytical as well as experimental values.
