“…To simplify the analysis, some assumptions are used [22][23][24][25][26][27][28][29][30]: (a) The stator iron has infinite permeability. The material of stator iron is silicon-steel sheet with 0.5 or 0.2mm thickness, whose permeability is about 2 000 times that of air gap or larger, so in most cases, the permeability of stator iron can be considered infinite.…”

The derivation of the equivalent circuit for a single-sided linear induction motor (S LIM) is not straightforward, particularly if it includes longitudinal end effects from the cut-open primary magnetic path, transversal edge effects from the differing widths between the primary lamination and secondary sheet, and half filled primary slots. This paper proposes an improved series equivalent circuit for this machine. The longitudinal end effects are estimated using three different impedances representing the normal, forwards and backwards flux density waves in the air-gap, whose two boundary conditions are deduced by introducing the conception of magnetic barrier surface. The transversal edge effects are accounted by correction coefficient t K and an air-gap flux density correction coefficient b K. Using the series circuit, the performance of the S LIM was assessed in a similar manner to a rotating induction machine. A 4 kW S LIM prototype was tested which validated the simulation technique.

“…THE PHYSICAL MODEL To simplify the analysis, some assumptions are used [6][7][8][9][10][11][12]: (a) the stator iron has infinite permeability; (b) skin effect is neglected in the secondary; (c) winding space harmonics are negligible; and (d) the primary and secondary currents flow in infinitesimally thin sheets. The structure and one-dimensional representation of the SLIM are shown in Fig.…”

The derivation of the equivalent circuit for a singlesided linear induction motor (SLIM) is not straightforward. Especially if it includes longitudinal end effects from the cutopen primary magnetic path, transverse edge effects from the differing widths between the primary lamination and secondary sheet, and half filled primary slots. This paper proposes an improved series equivalent circuit for this machine. The longitudinal end effects are estimated using three different impedances representing the normal, forwards and backwards flux density waves in the air-gap. The transverse edge effects accounted for with a correction coefficient K t and an air-gap flux density correction coefficient K b . Using the series circuit, the performance of the SLIM was assessed in a similar manner to a rotating induction machine. A 4 kW SLIM prototype was tested which validated the simulation technique.

“…Como em qualquer novo equipamento que surge através de pesquisas, um bom modo de iniciar a compreensão dos princípios físicos de uma MIL é comparando-a com uma MIR. Uma M1L pode ser, basicamente, definida como uma MIR cortada ao longo de um plano e estendida, como pode-se observar na [GUERRINI, 1972;SIMONE, 1989 1975;YAMAMURA, 1972;BOLDEA& NASAR, 1985;GIERAS, 1994].…”
