A METHOD OF OPTIMAL-DESIGN OF SINGLE-SIDED LINEAR INDUCTION-MOTOR FORTRANSIT

An optimal design method for a single-sided linear induction motor (SL IM) for transit is described. We propose the method which determines t he overall parameters of SLIM for transit using only the rated mechani cal output. When the optimization is carried out, the slot depth is us ed as the initial value so that the exact slot depth is calculated ite ratively from the circuit equation. The optimization problem of a SLIM design is approached by use of the sequential quadratic programming ( SQP). The influence of design variables is analyzed by the rated thrus t and the rated velocity respectively.
