Abstract
An electronically switched linear motor with high specific thrust characterized by large mechanical air gaps and by the absence of side thrust components. The motor can be completed by a built in linear sensor of the position. The generation of a high thrust is obtained through the effect of variable reluctance of two stator indented rails, whereas the side (sideway) thrust balancing is achieved thanks to a dual air gap symmetrical construction.
