Investigation of Design Parameters of Single Sided Linear Induction Motor for MAGLEV

Linear metro with single sided linear induction motor is applied to the urban transit system because of non adhesion drive. But linear induction motor is required to reduce the energy consumption to maximize efficiency of LIM. In this paper, design requirements such as pole pitch, motor length, air gap, overhang length and the material of secondary sheet are investigated as major parameter of SLIM. It is effective for increasing the efficiency to adopt the copper reaction plate and decrease the mechanical air gap as small as possible.
