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 performance of a high speed LIM is severely degraded by "End Effects".
The paper provides an overview of the modern field simulation techniques available to assist in the design and performance efficiency comparison of linear induction motor in terms Goodness factor (G) widely depends on the factor such as pole pitch , total air gap, input frequency & surfac e resistivity etc. The COMSOL multiphysics software used here is based on finite element techniques in very advanced and provides reliable and accurate results .
