چکیده مقاله:

methodfor modrfying special kind of end tlffect coefficient in equivalent circziit of Linear Induction Machine (LIM) is presented. Finite Element (FE) Model ofa LIM is analyzed to evaluate analytic studies and reszllts. The Finite Element model is constrzlcted by the windings voltages as input source. ,41so, relative velocity of primary and secondary is considered for calczrlations. Different jirnction of end effect in low-speed and high-speed LIMs is the basis for niodificution of LIIM eqzlivalen t circuit. It is shown that, the phenomenon of air-gap tht-zrst prohrction at synchronous speed in low-speed type of linear itiduction motor will be calculated by new equivalent circziif.
