Investigation of secondary slot pitches of a cage-type linear induction motor

Experimental and numerical studies are conducted on linear induction motors with cage-type rails in an effort to improve their motor characteristics in order to facilitate application of these motors to a new underground freight transport system. The framework of the study, based on the electric vector-potential formulation, is a visual representation of the secondary eddy-current path, as well as gap-flux distribution for assisting the motor designer
