Design Of An Elevator Prototype Propelled By A Linear Induction Motor

Abstract

This work aims at the design of a roped elevator prototype, which uses a linear induction motor (LIM) as a traction machine. It is also concerned with the development of a specific inverter to feed the linear motor that allows several ways to drive the elevator through a suitable choice of the RMS voltage levels, angular phase displacement and electrical frequency of the output voltage. The result tries to establish a new concept for elevators through a new construction technique and assembly of the system with counterweight, which increases the reliability and comfort with cost reduction.
