Abstract：This paper investigates double-sided linear induction motor (DSLIM) with ladder-slit type coreless secondary. The steady characteristics of induced eddy current in secondary is analyzed, the calculation formulas of resistance and leakage inductance of ladder-slit type secondary are deduced, and the equivalent circuit of ladder-slit type secondary DSLIM is proposed considering the contact resistance between secondary conductors and longitudinal end effect. Field-circuit coupled method is presented for analysis of ladder-slit type secondary DSLIM. The characteristics of locked DSLIM with plate and ladder-slit type secondary under the same primary are tested and calculated, which verify the validity of two calculation methods and show that the ladder-slit type secondary DSLIM can eliminate the second transverse end effects, standardize eddy current path, and improve the ratio of thrust to power.

Key words： Double sided linear induction motor ladder-slit type secondary end effects equivalent circuit thrust performance
