11 Linear Switched Reluctance Motors (L-SRM) Modeling, Design, and Control
Linear switched reluctance motors (L-SRMs) are counterparts of rotary switched reluctance motors [1, 2, 3]. The finite length of their magnetic circuit along the direction of motion introduces, for a small number of poles, some longitudinal static effects (asymmetries between phases). Also, the normal force has its peculiarities with L-RSM, but other than that, the theory developed for rotary SRMs may be adapted easily for linear SRMs.
So, as for rotary SRMs, L-SRM produces a thrust and motion by the tendency of a ferromagnetic secondary to hold a position where inductance of the active (excited) primary phase is maximum. Though it is in ...
