Analysis of Permanent Magnet Linear Induction Motor (PMLIM) Using Finite Element Method

The majority of electrical machines are designed to produce the rotary motion, there by exploiting the blessing of circularity which man has enjoyed since the discovery of the wheel. Electromagnetic forces may also be employed to produce the linear motion resulting in linear motion electrical machines. The paper provides an overview of the modern field simulation techniques available to assist in the design and performance prediction of electromagnetic devices, linear induction motor. This paper deals with the three typical performance characteristics of the permanent linear induction motor which affects the performance of the machine. The Comsol multiphysics software used here is based on finite element or related techniques in very advanced and provides a reliable and accurate results.
