Electromagnetic Analysis of Flux Characteristics of Double-Sided Switched Reluctance Linear Machine

A review on linear switched reluctance motor

“…When the stator houses the winding, it forms the primary and the configuration so obtained is referred to as active stator configuration (primary). This configuration has been adopted in developing actuators, drives for doors, industrial rails ( [11], [53], [57], [12], [18], [41], [32], [2], [17], [9], [43]). Similarly, when the translator houses the windings, the configuration is called an active translator or primary mover.…”

“…In the study, the LF configuration developed more levitating force with a lower secondary mass than the TF configuration. Lim and Krishnan [34] and others ( [35], [32], [18], [17], [9], [43]) has used a LF configuration as a model to study for its mechanical stability thereby optimize its performance characteristics. Liu and Kuo [37], Baoming et al [5] and Liu et al [40] has used a TF configuration to drive a wagon on wheels which obtained promising results in application.…”

“…In such configuration, the system has to deal with high attractive force which is difficult to control [14], [38]. Researchers adopted a twin symmetric primary design that eliminates the unbalanced attractive force ( [34], [35], [56], [18], [2], [9], [26], [6]). Further exploration in flexibility of configurations such as intermediate core [17], yokeless systems ( [34], [35], [17]) and permanent magnet embedded hybrid motors [7], [4] obtained better performance characteristics like mass to force ratio and reduction in force ripple.…”

“…A popular method of developing an analytical model is the reluctance network model from which magnetic flux linkages are estimated. Significant development in such network models ( [37], [29], [17], [9], [43], [6], [49], [51], [47], [1]) have resulted in better accuracy. However, finite element analysis still remains the most accurate method to obtain performance characteristics of the machine.…”

“…However, finite element analysis still remains the most accurate method to obtain performance characteristics of the machine. Estimating reluctance from flux tube method ( [12], [32], [17], [9], [6]) is popularly used to calculate reluctance or permeance deterministically, as a function of displacement of mover, to track changes of inductance with position [10]. Chen et al [9] has estimated the distribution of magnetic flux linkage in the air gap for six special mover positions.…”
