Simplified Calculation of Linear Induction Drives Characteristics
The paper presents new and simplified expressions for performance and mechanical characteristics of the linear induction motors (LIM). It enables to increase the speed of designing of different multifunction mechanisms of linear induction motors. On the base of the given expressions, results compared to experimentally and theoretically derived calculations with advanced origin conditions. The simplified computation methodology is based on facts, that theoretical mechanical characteristic of a low speed LIM crosses the speed axis over synchronous speed point because of influence of end effect and goes below the speed point because of asymmetry of currents. However in the first stage of design it is useful not to take into account LIM features which influences the different sign errors.
