Abstract :
In the vector control of a linear induction motor (LIM), it is difficult to calculate air gap field vector exactly because of end effects of LIM. So, this paper shows the longitudinal end effect and the transverse edge effect of LIM by experiment and determines the position of the sensor for detecting the air gap field vector. The direct vector control scheme is utilized to control the speed of LIM. As a result, simulation values by finite element analysis and experimental values of direct vector control using DSP are compared, and investigated
