ABSTRACT:
A linear synchronous motor, in which one or more intermediate annular magnetic pole portions and yoke assemblies can be connected easily while positioning the intermediate annular magnetic pole portions. A fitting concave portion that is opened in an axial direction and a direction away from a direct drive shaft is formed in each connected portion of the intermediate annular magnetic pole portions. A plurality of fitting grooves are formed on an outer peripheral surface of a pair of magnetic cylindrical members at a plurality of portions facing the plurality of intermediate annular magnetic pole portions. The intermediate annular magnetic pole portions are fixedly positioned between the pair of magnetic cylindrical members by fitting a peripheral portion defining the fitting concave portion of the intermediate annular magnetic pole portion into the corresponding fitting groove of the magnetic cylindrical member.
