Abstract

This paper describes the effect of multilayering on thrust force characteristics in compact Linear Switched Reluctance Motors (LSRMs) having a simple, flat shape. The Layer Structure Linear Switched Reluctance Motors (LS-LSRMs) basically comprise simple layer structure components such as a thin mover and a flat stator core for simple fabrication and for saving space. The use of the simple layer structure components facilitates the simple fabrication of multilayer actuators to generate a large thrust force. Themover consists ofmagnetic pieces sealed with nonmagnetic materials. The stator core is a single layer magnetic plate with fine beams. The force characteristics of two LS-LSRMs with one or two stator core layers were examined numerically. Then, their prototypes were fabricated and their force characteristics were measured. The results indicated that the multilayer structure was effective in increasing the effective thrust force.
