Abstract
A stator core unit of a linear synchronous motor is divided into a plurality of divided cores. The divided cores each include a pair of connected portions. The pairs of connected portions are disposed along a first direct drive shaft and a second direct drive shaft to form a pair of connected portion arrays. A yoke is constituted from a pair of yoke elements which are formed of a magnetic conductive material and magnetically connect the connected portions of the pair of connected portion arrays. A first array of permanent magnets and a second array of permanent magnets are disposed to be shifted from each other by an electrical angle of 180°. A first array of windings and a second array of windings are excited with the first and second arrays of windings being shifted by an electrical angle of 180°.
